ACKNOWLEDGEMENTS
This document is one of five Technical Support Documents that have been developed to
accompany international training workshops on the Principles of Environmental
Enforcement. They were developed as resource documents for government officials and
others who are motivated to try to reduce the adverse environmental impacts from
activities described in the case studies used for the course. The five case study areas
include:
o Mining (Metallic ores and Minerals),
o Petroleum Refining and Petrochemicals,
o Residential and Industrial (Solid) Waste Disposal
o Tourism, and
o Deforestation.
The documents provide an overview of the environmental impacts, pollution prevention
and control opportunities, range of institutional mechanisms to control adverse impacts,
and an annotated bibliography of selected reference materials. They do not address
institutional and program development issues surrounding regulatory and enforcement
programs. These topics, as well as country specific program examples are developed in
the Proceedings of the International Conferences on environmental compliance and
enforcement, UNEP institution-building workshop materials and new capacity building
documents under development for the Fourth International Conference scheduled to be
held in April, 1996 in Thailand.
International workshops on the Principles of Environmental Enforcement provide an
opportunity for governmental and non-governmental officials to discover and apply the
definitions, frameworks and principles to develop a successful management approach,
compliance strategy and enforcement program for any environmental problem in any
cultural or legal setting and to explore negotiated resolution of enforcement problems.
The Principles of Environmental Enforcement text and training was developed by the
U.S. Environmental Protection Agency in collaboration with the government of Poland
and in cooperation with the government of the Netherlands. It was adopted as a basis for
international exchange after having been successfully presented with this purpose in mind
at the Second International Conference on Environmental Enforcement held in
Budapest, Hungary, September 1992.
This document was produced under a Cooperative Agreement between the World
Wildlife Fund and the U.S. Environmental Protection Agency in cooperation with the
Netherlands Ministry of Housing, Spatial Planning and the Environment, The United
Nations Environment Program IE, and SEDESOL the Mexican Social Development
Ministry. The topic is one of five identified by an international Executive Planning
Committee for new case studies and stand-alone technical support materials to be used
in workshops on the Principles of Environmental Enforcement launched at the Third
International Conference on Environmental Enforcement held in Oaxaca, Mexico, April
25-28, 1994. Partial funding was also provided by the United States Agency for
International Development.

RESIDENTIAL AND INDUSTRIAL (SOLID) WASTE SUPPORT PACKAGE
1. INTRODUCTION AND SUMMARY
Population growth, rising standards of living increasing urbanization, and industrialization
all have contributed to increased solid waste generation in both industrialized and developing
countries. Solid wastes pose significant threats to public health and the environment if they are
not stored, collected, and disposed of properly. The most serious effects of improper solid
waste management include air pollution, contamination of drinking water supplies, and the
spread of human disease. These problems suggest the need for government policy-makers to
explore pollution prevention options and to consider regulatory and enforcement strategies to
minimize the harmful environmental impacts of improper solid waste management practices,
especially those used in landfilling, the main method of waste disposal in the world.
1.1 Purpose and Overview of the Solid Waste Support Package
This document is a general resource for governments and others about environmental
effects of solid waste. It introduces some of the methods available to prevent, control and
mitigate these impacts. More detailed sources of information are cited in the Annotated
Bibliography of Additional Sources section in the Appendix for those seeking more in-depth
technical or regulatory information.
The focus of this report is on solid waste landfilling, the most common method of solid
waste disposal worldwide. Since it is the most prevalent management option, land disposal
presents the greatest environmental challenges internationally. Other solid waste management
practices such as source reduction, collection, recycling, composting, and incineration are
discussed, but in considerably less detail. Of the remaining options, incineration can be most
harmful to the environment and public health when it is poorly controlled. Incineration,
however, is practiced only infrequently in developing countries since the technology is expensive
and waste streams in developing countries tend to have little heat content (i.e. in low-income
countries, waste contains only 2% paper compared to 31% paper in waste streams in
industrialized nations). Less sophisticated waste burning in open dumps, which is more
characteristic of many low-income and developing nations, is addressed in this support package.
Industrial hazardous waste - solids, sludges, and liquids that contain toxic levels of
metals, solvents, or organic or inorganic chemicals - also are not considered in this support
package. In most low-income countries, hazardous waste flows contribute only small
percentages of the total industrial and household solid waste stream. As industrialization
escalates, of course, these wastes can become a much more important problem. Several
documents cited in the Annotated Bibliography of Additional Sources (see the Appendix to this
package) address alternatives to prevent, contrail, or remediate impacts from industrial
hazardous waste.
-------
For purposes of this document, solid waste is defined as:
"Material for which the user (or generator) of the material abandoning the material
requires no compensation upon abandonment. This material is considered within the
responsibility of the government to ensure the proper collection and disposal of this
material."
Solid wastes are generated by residential, commercial, and industrial establishments.
Industrial wastes fall within the responsibility of the municipal government even though they are
often collected and disposed by private companies. All industrial and household hazardous
wastes which are disposed with non-hazardous solid wastes are considered within this definition.
Because solid waste is such a broad and complex topic, this package includes an extensive
bibliography of resources providing greater detail on issues that are only briefly discussed in this
document.
1.2 Solid Waste Management and the Environment
Solid waste management techniques vary from country to country depending upon
physical geography, demographics, and level of economic development. Most industrialized
countries have regular solid waste collection and disposal services. Most waste disposal sites
are required by law to have at least some environmental prevention and control technologies.
In contrast, most developing countries provide formal waste collection and disposal services to
only a portion of the population — the urban poor as well as residents of rural areas often have
no formal collection services or designated dumping areas. Even when areas are designated as
disposal sites, often they are open dumps that pose serious threats to public health and the
surrounding environment.
1.3 Toward Sustainable Development: Pollution Prevention and Control
The environmental effects of improperly disposed solid wastes can be controlled through
public education; economic incentives; careful planning; monitoring of waste flows; and
enforcement of clear, well-defined solid waste management regulations. Approaches must cover
all phases of solid waste management including storage of wastes at the point of generation,
waste collection, and waste disposal. Examples include:
• public education that demonstrates the linkages between poorly controlled solid
waste and environmental contamination or health risks;
• provision of containers or regulations that require controlled storage of solid
waste so that every generator has an adequate number of containers to store waste
between times of collection;
-------
• education, public programs, or private contracts that assure reliable central or
curbside collection consistent with storage requirements;
• regulations to control the construction and operation of collection and transport
vehicles to minimize odors, leakage, and litter; and
• education, incentives, or regulations that eliminate littering and the indiscriminate
disposal of solid waste - especially burning and open dumping.
The choice of management approach ultimately will depend on waste volume, waste
composition, local social and economic conditions, and the technological capabilities of local
communities. Waste flows per person in low-income countries, for example, typically are 1-3
times lower than in industrialized countries (see table 2a). Waste streams in low-income
countries also tend to be dense, wet, and dominated by vegetable matter. Recycling makes little
sense since few materials in this waste stream have residual value. Composting, on the other
hand, may be well-suited to the typical waste stream and socio-economics of low-income
countries. In industrialized countries, in contrast, waste has a much higher percentage of paper,
glass, and metal; it is not nearly as dense and much drier. Source separation, recycling, and
incineration of high-heat content residuals may make more sense for these countries.
Mechanisms to effect waste management options for each of these situations are likely to be
somewhat different.

PROFILE OF THE SOLID WASTE MANAGEMENT INDUSTRY
This section describes the characteristics and scope of the solid waste industry in low-
income, middle-income, and industrialized countries. Topics discussed include: waste stream
characteristics; and collection; transfer; and disposal practices.
2.1 Waste Stream Characteristics
How a country chooses to manage solid wastes depends upon the type and amount of
waste that it produces. Table 2(a) below describes the characteristics of urban wastes in low-
income, medium-income, and industrialized countries. Countries are categorized according to
their mean annual income per capita: low income countries less than US$360, middle income
between US$360 and US$3,500, and industrialized greater than US$3,500.

2.1.1 Waste Generation
Comparisons of waste generation rates are inevitably crude because few governments
know how much waste is made and there is no consistent definition of what constitutes municipal
solid waste and hazardous wastes. For example, some countries consider construction and
demolition debris as part of the municipal waste stream, while others do not.
Despite these difficulties, there is general agreement that residents of industrialized
countries dispose of much more waste than residents of developing countries. A recent World
Bank study found that urban areas in industrialized countries generate 2 to 3 times more waste
per capita than low income nations (see Table 2(a)). In developing countries, waste is a luxury
available to only the wealthy minority. Most wastes are recycled or reused by residents who
scavenge through the waste stream for valuable materials.
Industrialized countries generate fewer wastes as their economy grows and a greater
proportion of income is spent on services, such as education and health, which generate less
waste per dollar spent. For example, between 1980 and 1990, per capita municipal waste
generation in the United States grew by only 0.5 percent a year compared with an increase in
the size of the U.S. economy per capita of 1.9 percent per year. Section 2.5.1 below discusses
the importance of efforts to reduce waste generation through source reduction and reuse of
materials.
2.1.2 Waste Density
The density of waste is inversely related to the amount of waste generated. In other
words, countries with high per capita waste generation rates (i.e. industrialized countries)
produce waste that is of a lower density than waste produced by countries with low per capita
waste generation (i.e. developing countries). Waste densities are between 2 and 5 times higher
in low income countries (see Table 2(a)). Industrialized countries produce lower density waste
because they generate a higher percentage of paper, plastic, glass, and metals which are often
used as packaging materials for consumer goods. These materials have large open spaces (i.e.
an uncompacted tin can) and a low moisture content. In contrast, developing countries produce
a higher percentage of food wastes, which has less open spaces and a high moisture content.
The moisture content of wastes in developing countries is higher because it has a higher
percentage of food (vegetable) wastes and the waste is often stored on the open ground awaiting
collection.
2.1.3 Waste Composition
Waste from low- and middle- income countries contains fewer paper products and non-
food items than waste from industrialized countries. The composition of solid waste is a key
-------
determinant in decisions concerning types of vehicles needed for collection and transfer,
requirements for final disposal, and resource recovery alternatives.
In both developing and industrialized countries, the waste stream may become
contaminated by human and hazardous wastes. In developing countries human wastes are mixed
into the waste stream when there are inadequacies with the sewage system. In more
industrialized countries, most of the human wastes comes from disposal diapers.
Hazardous wastes are generated by residents and industry. Residents dispose of
household hazardous wastes such as batteries, used motor oil, and cleaning solutions. Industry
can generate substantial amounts of hazardous wastes such as industrial solvents. While the
degree of industrialization in developed countries is much greater than in developing countries,
the ratio of industrial hazardous wastes to total industrial wastes is similar. In the United States,
approximately 10 to 15 percent of all industrial wastes are classified as hazardous.2
2.2 Provision of Solid Waste Management Services
Most countries place the responsibility for collection and disposal of solid wastes on the
local municipal government. In some cases, the local government provides collection and
disposal services directly while in others, the local government contracts these services out to
the private sector. Contracting waste management services to the private sector is becoming an
increasingly popular way of providing waste services at lower cost in many industrialized
countries. In the United States, more than 80 percent of the nation's municipal solid waste is
collected by private firms and 7 percent of the landfills and 73 percent of the resource recovery
facilities are operated by private contractors. The costs for providing solid waste management
service in Sao Paulo using private contractors is less than half that in Rio de Janeiro which uses
a publicly run system. Privatization in lower-income countries is somewhat limited as few
companies have expertise in solid waste management and foreign investment is not encouraged.
2.3 Solid Waste Collection
This section describes solid waste collection practices in low-income, middle-income, and
industrialized countries. Three main issue areas are discussed: provision of collection services;
waste storage, and collection vehicles. Where possible, comparisons are made between
collection practices in developing versus industrialized countries.
2.3.1 Provision of Collection Services
Although most urban areas in developing countries have waste collection services, this
service is usually not available to all sectors of the population. Waste is usually collected from
the high and middle income areas of the city but not in the lower-income areas. Lower-income
areas have poor roads making it difficult for waste collection vehicles to assess the area, and
-------
generate fewer recyclables making it less profitable to recover materials from the waste stream.
In Latin American countries, the average service coverage for cities in the region is about 70
percent — ranging from 50-70 percent in smaller cities to 85-90 percent in larger ones. Thus,
about 30 percent of the garbage in the region, or some 20 - 25 million tons a year, is not
collected at all.3 Frequent collection services are needed to prevent health problems, especially
in regions with high temperatures and humidity where solid wastes decompose and decay
rapidly. For example, in Colombia, uncollected refuse can cause malaria. The uncollected
refuse blocks storm drains and creates stagnant pools of water where malaria-carrying
mosquitoes breed.
In areas which have waste collection, other problems occur such as residential
cooperation and frequent collection vehicle breakdowns. Residents put their garbage out on the
wrong days or in open piles or inappropriate containers. These inappropriate collection practices
not only increase litter and threaten public health but also increase the cost of collection. Many
developing countries are trying to improve collection practices through education programs.
Another problem is the frequency in which collection vehicles breakdown. This is common in
developing countries where insufficient budgets make it impossible to provide adequate
maintenance. Downtimes of 40 to 60 percent are common for collection vehicles in developing
countries compared with 5 to 15 percent downtimes in industrialized countries.4 Development
of preventive maintenance programs and educational efforts may very helpful in certain
locations.
2.3.2 Storage of Waste at the Source of Generation
Waste can be stored at the source of generation in a variety of containers including
household storage bins and communal storage bins. Household storage bins are used to store
waste generated from a single household or business and are either provided by the collection
agency or the waste generator. Communal storage bins are usually used to provide service to
neighborhoods or apartment complexes. The type of storage container dictates how the waste is
collected and the efficiency of the collection process. Improper storage methods increase litter,
threaten public health, and increase the cost of collection.
2.3.3 Collection Vehicles
There are basically three types of waste collection vehicles: those that are human-
powered, animal-powered, and engine-powered. Each of these vehicles give different levels of
service and require different levels of skills to operate. Human-powered equipment includes
pushcarts, pedal tricycles, and wheelbarrows. This equipment is commonly used in collection
areas with limited access, such as narrow streets. Animal-powered equipment includes carts
drawn by animals or animals that are saddled with collection containers. Animal-powered
equipment is often used on hilly, unpaved, and/or narrow streets. Engine-powered collection
equipment includes tractors that pull wheeled containers (tractor trailers), flat bed trucks, and
-------
trucks with mechanized compaction equipment. In general, compaction trucks are not needed
in developing countries because of the higher density of waste. (Compaction trucks achieve a
compaction ratio of 4:1 in industrialized countries and only a 1.5:1 ratio in developing
countries.) Table 2(b) below summarizes the characteristics of these collection vehicles.

2.4 Solid Waste Transfer
Solid waste that is collected from an area may either be hauled directly to the disposal
site by the collection equipment or it may be transferred to another size or type of equipment
for hauling. In general, waste transfer is economical when the disposal site is located
sufficiently far from the collection area. Transferring waste to a larger or more efficient
hauling vehicle allows the collection vehicle to maximize its time on its collection route and for
the collection crew to maximize its time collecting wastes. Typically, waste is transferred at a
transfer station where waste is dumped onto a platform and then pushed (or dumped) into the
larger collection vehicle. In many cities, waste is transferred into rail cars or barges for
transport to the disposal site.
-------
2.5 Solid Waste Disposal and Management Techniques
Landfilling is by far the most common method of waste management in both
industrialized and developing countries because it is generally less expensive than the alternatives
of incinerating, composting or recycling. In the lower-income countries, waste is most often
disposed in open dumps with few, if any environmental controls. Some recycling is done by
scavengers and other resource recovery options such as composting and incineration are not
widely used.
In industrialized countries, landfills are usually required to install some types of pollution
prevention and environmental controls. Even with these more stringent control requirements,
landfilling is still often the least cost method of disposal. For example, when compared with
per ton incineration costs, landfilling in Germany is $70 per ton cheaper and $20 per ton cheaper
in the United States.6 Table 2(c) below presents the percentage of waste landfilled in numerous
industrialized countries.

Industrialized countries are becoming aware of the environmental problems caused by waste
generation and disposal and many use more environmentally friendly methods of waste management such
as waste composting and recycling. In support of this movement, the United Nations Environment
Programme has endorsed a common approach to waste management — the waste management hierarchy.
This hierarchy lists waste management alternatives in order of priority: source reduction (decreasing waste
generation), direct reuse of products, recycling and composting, incineration with energy recovery, and
as the last resort - landfilling. This hierarchy is primarily used as a planning tool and to date, waste
management options have not been applied in this order. For example, in 1992, the United States
generated approximately 292 million tons of solid waste, of which approximately 72 percent was
landfilled, 17 was recycled or composted, and 11 percent incinerated.8
10
-------
Table 2(d) below compares the solid waste management practices in low-income, middle-income
and industrialized countries. It should be noted that some nations have much higher recycling rates or
more materials reuse than others, partly because of governmental efforts to encourage recycling and reuse
as a means of waste management. Reusable beverage containers, for example, are very common in
certain European nations.

2.5.1 Source Reduction and Reuse
Although pollution control through technology has historically received much attention,
pollution prevention is in many cases a less expensive method of managing wastes, and can be
11
-------
particularly helpful in nations with limited financial resources. One means of pollution
prevention is source reduction. Source reduction is the most basic and sometimes the least
costly method of waste management. Source reduction involves the management of materials
before end disposal to reduce the volume or toxicity of materials. Source reduction extends the
useful life of landfills as well as reduces the toxicity of the waste stream that is landfilled or
incinerated. Many nations apply financial incentives or requirements so that companies or
households will produce less hazardous waste.
The reuse of materials is another important form of pollution prevention. Some countries
encourage the production of goods that can be easily reused, such as refillable bottles, or
products with longer useful lives. These changes reduce the amount of waste generated per
year.
Source reduction and reuse are regularly undertaken in developing countries (although
primarily for economic, rather than environmental, reasons), while these are only beginning to
be practiced widely in industrialized countries. Several obstacles have precluded waste
prevention efforts including manufacturing decision and consumer buying patterns. For
example, manufacturers have little incentive to consider the cost of waste collection and disposal
when designing a product because consumers do not take these factors into consideration when
making purchasing decisions. Likewise, consumers demand more convenient and disposal
products which contain higher amounts of packaging material.
2.5.2 Composting
Composting involves separating organic materials such as paper and food wastes from
solid wastes and allowing the material to decompose into an organic end-product. Composting
is most common in industrialized countries even though, on average, 60 percent of the solid
waste produced in low-income countries is compostable compared with less than 35 percent of
the waste produced in industrialized countries (See Table 2(a)). Composting is more widely
used in developing countries where the climate is arid and the soil needs organic supplements.
Composting is becoming more widespread in industrialized nations, especially to manage leaf
and yard wastes. The major obstacles to composting are the limited markets for compost use
and environmental concerns about industrial or toxic wastes that may enter the waste stream and
end up in the compost.
12
-------
2.5.3 Recycling
Recycling involves separating reusable materials such as metals, glass, and paper from
solid waste. The recyclable materials are then processed and returned to the economy as parts
of other products. Recycling offers many benefits including:
• reduced environmental impacts because of reduced waste disposal;
• improvement in the cost effectiveness of waste-handling and disposal by providing
income from recycled materials and products;
• extension of landfill life and improvement of landfill management;
• conservation of natural resources and energy savings in production of new materials (e.g.
using scrap aluminum saves energy over using virgin ore);
• generation of economic activity and employment opportunities;
• reduction of dependence on imported goods and raw materials.9
Recycling has become increasingly popular in industrialized countries given the high costs
and environmental concerns associated with incineration and landfilling. Some nations promote
recycling through various types of financial incentives, active development and support of
markets for used goods, government purchases of materials made from recycled substances, or
requirements that consumers recycle certain materials. Support for the development of markets
for secondary materials (e.g. scrap paper) has been particularly important in the success of
efforts to increase recycling rates.
Recyclables are usually separated at the point of generation and sent to a materials
recovery facility for processing. In industrialized countries, the largest hurdle to recycling is
developing sufficient demand for recycled products to make it cost-effective. For example,
demand for recycled plastic is limited since it can not be used to make food containers because
of the danger of contamination. In addition, many consumers have reservations as to the
consistent quality and dependable supply of products made from recycled materials.
13
-------
Recycling is also common in developing countries. Most of the recycling is performed
by scavengers who pick through the waste stream (either at the point of collection, transfer or
disposal) to recover high value materials. In some low-income countries, scavengers recycle as
much as 10 percent of the waste stream, and sometimes these activities are encouraged as a
source of income and an effective means of waste reduction. However, scavenging may pose
health and safety problems for the people (often children) sorting through wastes at landfills.
Segregation of materials before they are disposed of by households, using separate bins at the
curb for different materials, or separation at a special facility, can be safer than scavenging at
landfills.
2.5.4 Incineration
Another method of solid waste disposal is incineration. In the incineration process,
wastes are burned at very high temperatures and by-products are released into the atmosphere
and concentrated into incineration ash. The by-products which are released into the atmosphere
contain dust, acidic gases, vaporized metals, toxic chemicals such as dioxin, all of which have
been linked to public health and environmental degradation. These by-products can be reduced
with a variety of air pollution technologies such as scrubbers which remove particulates before
they are released into the atmosphere. The incinerator ash is highly toxic as it contains a high
concentration of heavy metals, which stay in the incinerator while other wastes are burned, from
batteries and other waste products. Products such as batteries may be banned from or removed
from the waste stream and recycled before incineration. Because ash is highly toxic, many
industrial countries limit ash disposal to landfills which have extensive leachate control systems.
Recently, new technologies have made it possible to incinerate wastes while at the same time
recovering steam, electricity, or industrial heat. Energy recovery is widely used in the United
States and Canada.
Even with energy recovery, incineration is more expensive than landfilling in most
developing countries, and as such, incineration is rarely undertaken in developing countries
without assistance from regional or international aid organizations. Waste from low-income
countries is less suitable for incineration than waste from higher income countries because it has
a higher percentage of moisture and non-burnable inert materials such as ash and sand. It
requires more energy and is therefore more expensive to burn waste with a high moisture
content.
2.5.5 Landfill
Landfilling is the main method of disposal of municipal solid wastes in most countries.
Unlike composting and incineration, landfilling is not capital intensive and does not require
skilled laborers. Landfills dispose of municipal solid wastes directly, as well as the residues that
14
-------
remain after recycling, composting, and incineration. Regardless of the level of technology
used, landfilling is a very simple process — waste is dumped into a disposal area where,
depending upon the type of landfill, the material may be compacted, and covered with a layer
of soil. Over time, organic wastes such as paper and food wastes decompose to produce
methane, carbon dioxide, water, organic acids, and other chemicals. The rate of decomposition
depends upon many factors including moisture content, pH, temperature, degree of compaction,
and waste age and composition. When degradation occurs, the volume of the original waste is
reduced, providing additional landfill capacity. Strong odors are emitted as the organic wastes
decompose. Inorganic wastes such as metals and glass do not decompose, and remain
essentially unchanged over time.
There are three types of landfills, each defined by the extent to which they use
environmental and public health and safety controls: low, medium, and high technology landfills.
In general, most landfills in industrialized countries have environmental control technologies and
are classified as medium and high technology sites. Developing countries have landfills that
have few if any environmental controls and are classified as open dumps or low technology
landfills. There are major exceptions, however, as high-technology landfills have been built in
developing countries, including a large landfill in Monterey, Mexico. Most high-technology
landfills that are properly operated can safely handle both municipal solid and industrial
hazardous waste.
3. PRINCIPAL CONTROL AND PREVENTION OPTIONS TO MINIMIZE
ENVIRONMENTAL IMPACTS OF LANDFILLING
Whether a landfill causes environmental problems depends upon a number of factors
including: the composition of the waste, the rate of decomposition, the hydrogeology of the site,
rainfall, distance to aquifers, types of liners and covers, runoff controls, and the ability to collect
leachate and gas. This section describes the most common environmental problems associated
with solid waste landfilling and possible environmental controls. Each environmental control
is discussed separately below, but in practice they should be considered as integrated elements
in a single system.
3.1 Summary of Landfill-Related Pollution Prevention and Control Options
Landfilling can pose significant public health hazards and environmental degradation.
The most effective way to prevent this degradation is to limit where landfills can be located and
15
-------
to control the disposal of toxic and hazardous wastes at the site. If prevention techniques are
not effective, control technologies must be utilized to address three environmental problems:
groundwater contamination, surface water contamination, and air pollution. These problems as
well as possible environmental controls are described below.
3.2 Pollution Prevention Options Specific to Landfills
3.2.1 Avoiding Toxic and Hazardous Waste Contamination
Perhaps the largest single factor in determining whether or not a landfill poses significant
threats to public health and the environmental is the amount of toxic materials disposed at the
site. While pollution prevention is discussed in section 2.5, one sort of "prevention" that applies
specifically to landfills is to prevent hazardous wastes from entering solid waste landfills.
Although this is not true pollution prevention, it does keep hazardous wastes from being disposed
of in landfills not designed for such waste. Many industrialized countries have imposed
regulations which ban industrial hazardous wastes from municipal solid waste landfills, where
environmental controls are typically less effective than at true hazardous waste landfills.
3.2.2 Siting Landfills Away from Sensitive Areas
An important factor in determining whether or not a landfill poses significant threats to
public health and the environment is location. Groundwater contamination is less likely at a
site that has clay soils and a groundwater table far below the disposal area while surface water
contamination is less likely at sites distant from lakes and rivers. Air pollution is less of a threat
to public health if the landfill is located far from human settlements. Furthermore, siting in
wetlands or other sensitive areas can cause significant damage to local plant and animal species.
Of course, siting in any natural habitat causes loss or disruption of habitat and associated plants
and animals. Siting in floodplains can cause a loss of floodwater retention capacity, resulting
in higher flood levels and causing flood damage in the area.
Many countries control where landfills are located by requiring that all facilities obtain
a siting permit. Compared to costly high-technology solutions, proper siting can be an
inexpensive means of preventing environmental health problems, particularly well suited to
nations with limited financial resources. Of course, it cannot be seen as a complete solution,
since other types of pollution prevention or control technologies will be necessary.
16
-------
In some developed nations, the legal costs of obtaining a permit to develop a landfill can
be quite high, especially when the proposed site is near a community which opposes the facility.
In the United States, the cost of getting a permit to develop a landfill site can cost $500,000 or
more even before the expense of buying land. Most of the money goes toward convincing the
public that it is acceptable to site a facility in their community. Because of these high costs,
much of the new landfill capacity comes from expansion of existing landfills rather than siting
new ones.
3.3 Environmental Controls: Water Pollution
3.3.1 Groundwater Contamination
Groundwater contamination is the most common means of environmental degradation
associated with solid waste landfilling. Groundwater contamination occurs when liquids from
rainfall, moisture in the waste itself, or decomposition, percolate through the landfill and carry
chemicals through the landfill and soil to the groundwater. This liquid, or leachate, is generally
toxic and may become more toxic if it becomes mixed with hazardous wastes such as household
cleaners or industrial solvents. The extent of groundwater contamination depends upon the
amount of contaminants in the leachate, the ability of the soils under the landfill to absorb or
filter water contaminants, and the depth of the groundwater table. Groundwater contamination
is, for the most part, not a problem in very dry climates where rainfall is limited and where the
groundwater table is located far below the disposal area.
The most effective way of eliminating the threat of groundwater contamination is to
exclude the disposal of hazardous wastes at the site and ensure that the landfill is sited properly
(i.e. not located where groundwater contamination can easily occur). A more expensive method
of control, used in high-technology landfills, is to install either a plastic liner or a layer of clay
soil along the bottom of the landfill to reduce the migration of leachate to groundwater beneath
the site. No liner is guaranteed to be a permanent solution, but can very significantly delay or
mitigate environmental contamination.
Some modern landfills use cellular construction, a system where a section of the landfill
perhaps 4 to 40 hectares in size -- one cell - is separated from other parts of the landfill with
a liner. Keeping cells insulated from each other allows better control of leakage, allowing
detection of leakage from a single cell and remediation of that one cell.
Leachate may be collected, either through simple ditches or a more complex system
including pipes. Various methods are used to manage collected leachate, including transport to
17
-------
a sewage treatment plant, on-site chemical or biological treatment, or recirculation through the
landfill. In order to detect any possible leakage, additional pipes are sometimes placed
underneath liners, where groundwater may be monitored for signs of leakage.
Finally, cells or entire landfills may be covered, or "capped", once full, as described in
section 3.6 below.
3.3.2 Surface Water Contamination
Surface waters such as streams and lakes may also become polluted from landfill
operations. Rain water flows across the landfill, and into surrounding surface waters (i.e. lakes,
rivers). This rain water picks up and carries with it, depending upon the level of rainfall, a
portion of the landfill cover material, solid waste, and percolating leachate.
As with groundwater contamination, the most effective way to control surface water
contamination is proper siting and then to ensure that hazardous wastes are not disposed of in
landfills designed to manage only normal, solid wastes. If a special hazardous waste landfill is
not available, a solid waste landfill may be modified to provide at least some temporary control
of hazardous wastes.
The most common way to reduce surface water contamination is to build drainage canals
around the perimeter of the site to prevent surface waters from entering the site. In more
inexpensive, low-technology landfills these drainage canals are unlined. In more costly, high-
technology landfills, which provide much more effective control of leachate, these canals are
lined with either plastic or cement. In either case, contaminated surface waters may be captured
in canals and diverted into a holding pond. The run-off accumulates in the holding pond and
is either treated on-site or off-site or left to percolate into the soil and underlying groundwater
table. As described in section 3.6, landfills may be covered once full, providing further control
of water pollution.
3.4 Environmental Controls: Air Pollution
Municipal solid waste landfills generate several gases that pose risks to the environment
and public health. The primary gases are methane and carbon dioxide. A number of factors
influence the composition and amount of gas produced including: the amount and composition
of the degradable waste and leachate, the type and thickness of soil covering, and waste
placement techniques and site tipping history.
18
-------
There are two causes of air pollution at solid waste landfills: waste burning and waste
decomposition. Waste fires are common at open landfills in developing countries. Many fires
are set intentionally to reduce the volume of waste at the site. Other fires occur when organic
wastes that are exposed to the sunlight spontaneously combust. Waste burning is controlled by
enacting regulations which prohibit open burning and require that a layer of cover material be
placed over the fill area each day.
The second cause of air pollution, waste decomposition, causes pollution when methane
and other gases are released into the atmosphere as organic wastes anaerobically (i.e. without
oxygen) decompose in the landfill. It is estimated that 7 per cent of the total methane emissions
in the world come from landfill sites.10 These gases may explode under certain conditions if
not managed correctly. Methane and other gas releases are controlled by diverting the gas into
a pipe where the gas can be monitored and in some instances, burned. This gas is sometimes
collected at the site and sold as methane fuel or used to generate power on-site. Landfill gas
exploitation is common in the United States and is becoming more popular in some parts of
Western Europe such as Britain, France and Germany.
3.5 Environmental Controls: Public Health and Safety
A landfill has many potential public health and safety problems if it is not properly
engineered and operated:
• Waste disposal, especially in open areas, attracts rodents, insects, and birds which can
spread disease;
• Pathogens can be directly inhaled as wind transports fine-grained waste contaminants; and
• Children playing at the dump as well as human scavengers are exposed to disease or
toxic chemicals and injure themselves on sharp objects in and around the landfill.
The most effective way to address these concerns is to: compact the waste, apply daily
cover material, and limit access to the disposal site. Waste should be compacted once it is
placed in the fill area to decrease the amount of standing water where insects can proliferate.
In developing countries, waste is commonly compacted with hand tools, while in industrialized
countries bulldozers or other types of heavy machinery is used. Installing fencing around the
site decreases the number of children and scavengers at the dump site.
19
-------
3.6 Environmental Controls: Landfill Closure and Reclamation
When a landfill closes, measures are often taken to minimize the future environmental
impact of the abandoned landfill site, as well as to ensure the safety of surrounding residents.
Often efforts are made to make the site into a area that can be used by the entire community
such as a playground or park. Reclamation activity is often aimed at establishing a permanently-
stable landscape that is environmentally compatible with the surrounding ecosystem.
Landfill closure typically involves covering or "capping" the landfill area, and reclaiming
and revegetating the land disturbed during site operations. Often these closure activities are less
expensive and more effective if they are planned for early in the life of a site. Many
governments therefore require that plans for landfill closure be included in official plans (i.e.,
environmental impact assessments required in the U.S.) developed before operations begin.
Without appropriate action, surface water and groundwater contamination may continue
for many years after operations cease. Cover systems for landfill areas are used to minimize
these lingering effects. Cover systems generally include some area cap overlaid with a material
capable of supporting vegetation. Capping entails the placement of a layer of material composed
of natural soils and rock, clays, and/or synthetic liners over the landfill. Multilayered caps
consisting of a layer of plant growth, a layer of loose soil that allows drainage, and a hard layer
that prevent exposure of fill materials are the most common. In addition, surface water and
groundwater runoff from sites can still be monitored, and contaminated water treated using the
techniques described above.
After the fill area is capped, the landfill site can be reclaimed through restoration of the
area and revegetation of the land. Revegetation minimizes erosion at landfill sites, reduces
wind-blown litter, absorbs contaminants harmful to humans, and helps reestablish natural
ecosystems in the surrounding area. The ability of post-landfill area to support plant life is
determined by the properties of the soil in the area where plants lay down their roots.
Successful revegetation may not be possible in some cases, and it may be very difficult to restore
completely the original, natural environment. Generally, plant materials must be limited to
shallow-rooted grasses and forbs that will not penetrate the landfill cap.

4. PLANNING, MONITORING, ENFORCEMENT AND COMPLIANCE
APPROACHES
4.1 Level of Implementation
Compliance promotion activities can be undertaken at the federal, state, regional, and
local levels. Some countries, such as the United States and Germany, are moving in the
direction of developing more regulations at the national level for the design and operation of
sanitary landfills. The Sample Landfill Regulations section in the Appendix contains a brief
description of the national landfill policies recently passed in the United States.
4.2 Monitoring
Company-managed environmental monitoring and reporting systems can supplement
government enforcement effort. Of course, the government will have to enforce any
requirements to ensure that companies conduct monitoring and reporting correctly. It may be
useful to monitor some or all of the following at a landfill:
• surface water quality at or near the site;
• groundwater quality;
• air quality;
• samples of waste entering the landfill;
• extent of soil erosion; and
• extent of trespassing on site.
Important water quality parameters to monitor include: pH; biological oxygen demand;
chemical oxygen demand; nitrates; sulfates; fecal coliform levels; and various levels of toxic
chemicals. Such monitoring programs can improve cooperation between government and
industry, reduce costs, and still provide adequate environmental protection in some instances.
4.3 Regulatory Approaches
In most countries, solid waste management, like other government and private sector
activities, is subject to laws, regulations, and standards in many areas of operation.
Environmental requirements such as control of water contamination are sometimes incorporated
into these laws. Although solid waste landfill laws are rarely specific and extensive enough to
22
-------
be considered a complete environmental control program, they often draw upon laws in related
areas (e.g. general environmental legislation, and/or legislation on health, safety, and chemicals)
to provide a legal framework for environmental protection. Some environmental issues that solid
waste landfill laws can incorporate into specific regulations include:
• Ground water monitoring;
• Establishment of wastewater retention and treatment techniques, and safe
management of contaminated runoff;
• Monitoring and control of on-site toxic and hazardous waste disposal;
• Soil erosion control and revegetation procedures during operation and after
closure;
In addition, related legislation may cover aspects of environmental regulation of direct
concern to the solid waste industry, including:
• Laws governing land use and the impact of development on endangered species,
tropical forests, and flora and fauna;
• Laws governing the impact of development on indigenous cultures;
• Water quality laws that limit discharges into streams or rivers;
• "Clean Air" laws that govern emissions of toxins in gases or dust; and
• Controls for soil contamination by wastes and chemicals.
These environmental regulations can be packaged in a number of ways, depending in part
on the existence of an environmental legal framework apart from laws governing landfilling.
New laws can be crafted to build on, and be consistent with the existing legal structure. The
appendix at the end of this document shows excerpts from environmental landfill laws and
regulations in Italy, Poland, the United States, Denmark, Columbia, and Mexico.
4.4 Compliance Promotion
Government should be aware that requiring environmental control technologies increases
the cost of waste disposal, which in turn, creates incentives for non-compliance and illegal
dumping.
23
-------
In general, problems with solid waste enforcement are common in developing countries.
In Santiago, Chile, substantial portions of many municipalities are exempted from property tax,
thus placing the burden of cost recovery on a minority of lower- and middle-income residents.
In most cities, enforcement is weak, and non-paying customers, who are denied service, dump
their waste illegally. To avoid non-payment of waste collection fees, some institutions have
entrusted their billing and collection to a water or power utility11
Many developing countries have laws which prohibit littering and open dumping,
although these laws are seldom seriously enforced.12
There are six approaches to compliance promotion:
• Providing education and technical assistance to the regulated community;
• Building public support;
• Publicizing success stories;
• Creative financial arrangements;
• Providing economic incentives; and
• Building environmental management capability within the regulated
community.
Actual examples of two of these methods of compliance promotion are described below.
4.4.1 Providing Education and Technical Assistance to the Regulated Community
By law, commercial establishments in the Netherlands are required to dispose of their
hazardous wastes through permitted processors. However, getting the waste to the processor
has been a problem for small businesses. The processors are often unwilling to pick up small
amounts of wastes, and transporting small quantities of waste long distances to a processor
places an economic burden on small businesses. Small companies were therefore often out of
compliance with the hazardous waste rules. The Dutch government helped to solve this problem
by establishing a collection depot in nearly every town. Both private citizens and small
companies may discard their waste at these depots at regular times. This government-facilitated
cooperative arrangement was instrumental in helping solve this compliance problem.13
24
-------
4.4.2 Building Public Support
New York State recently passed legislation requiring all municipalities to reduce waste
streams. In order to comply with this regulation, the New York City Department of
Sanitation undertook an extensive public education campaign to teach people to how to
generate less waste and how to recycle. The Department of Sanitation, in conjunction with
various non-profit organizations, successfully built public support by developing and
distributing information about environmental problems, the importance of compliance,
program activities and successes, and ways the public can support the program.
4.5 Compliance and Enforcement Programs
This Technical Support Document is intended to accompany the Principles of
Environmental Enforcement Text, U.S. EPA, which describes the basic elements and
approaches for establishing effective compliance strategies and enforcement programs. As
a supplement to international efforts to advance effective environmental compliance and
enforcement programs, the readers are referred as well to the UNEP IE training manual on
Institution Building for Industrial Compliance and Proceedings of the series of International
Conferences on Environmental Compliance and Enforcement for further discussion of these
programs.

5. APPENDICES
5.1 APPENDIX 1: Sample Landfill Regulations
The references in the bibliography can direct the reader to many examples of regulations,
but some excerpts are provided here as illustrations.
5.1.1 Defining Waste: Milan, Italy
The Italian law defines wastes as "any substance or object derived from human activities
or natural causes that is abandoned or destined to be abandoned." The disposal of wastes,
including its storage, treatment to facilitate partial or complete reuse, landfill, etc. is undertaken
observing the following principles:
• avoidance of the risk of damage or deterioration in the well-being or health of one
or more individuals:
• guarantee that every precaution is taken to avoid pollution of the air, water, soil
or subsoil and that unacceptable noise and odor pollution are not caused;
• protect flora and fauna and prevent deterioration of the countryside;
• respect economic and land planning; and
• use disposal methods which maximize the reuse or recovery of resources
contained in the waste.14
5.1.2 Siting: Poland
In 1973, Poland's Ministry of Land Management and Environmental Protection, adopted
the Code of Practice, issued by the World Health Organization, as a guideline for landfill
design. According to these guidelines, the following criteria must be met in siting a new
landfill:
• suitable geological and hydrological conditions including low
permeability/filtration coefficient of the soil;
• natural or artificial re-entrants, e.g. clay headings, located a suitable distance
from the building site, guaranteeing a proper sanitary protection zone;
• soil of low productivity class at the area covered by the new landfill; and
• good connection to the existing road networks.
26
-------
5.1.3 Siting, Operation and Closure: United States
In 1994, new landfill regulations that are part of the federal Resource Conservation and
Recovery Act (RCRA) went into effect. These rules set minimum criteria for where landfills
can be located, how they're designed, and how they must be operated and eventually shut down.
State government must implement programs for assessing whether or not landfills comply with
the new regulations before granting waste disposal permits. These new landfill regulations are
summarized below.
1) Location. Landfills cannot be sited on wetland, floodplains, earthquake-prone areas,
unstable geological formations, or property close to airports. Existing areas near
airports, floodplains or other unstable areas must be closed by a certain deadline unless
engineering measures can be used to ensure that they operate safely.
2) Linings. The bottom and side of a landfill must be lined with a plastic liner beneath
which there must be at least two feet of clay.
3) Leachate. To keep contaminants from leaking, landfills must capture leachate fluids
in drainage layers, remove them through a system of pipes and pumps, and treat the
leachate before releasing it into streams or the land surface.
4) Gas Control. To prevent explosions, landfill operators must monitor the gases that
landfills give off as waste decays. If concentrations of gas are too high, landfills will
have to install pipes to collect the gas. Air pollution regulations may require the methane
and other landfill gases be collected in order to control odors, protect public health and
combat global warming.
5) Groundwater. All landfills must install perimeter wells to monitor and detect
contamination in nearby groundwater. If contaminants are found, environmental threats
must be assessed and corrected.
6) Toxics. Operators must check for and remove regulated hazardous wastes and PCBs
from garbage loads before they are deposited in solid waste landfills. Bulk liquid wastes
that are not held in containers cannot be dumped. Operators are to screen waste
deliveries at random to search for unacceptable materials.
7) Cover Soil. At the end of each day, the garbage must be covered with 6 inches (15.2
centimeters) of earthen material. When a landfill reaches capacity, operators must apply
19 inches (48.3 centimeters) of earthen material to keep moisture out of the disposal
area, below 6 inches of additional cover material to support natural vegetation and
prevent erosion of the cover material. States with their own EPA-approved regulations
27
-------
can allow operators to use plastic covers, foam sprays and other materials that take up
less air space than soil.
8) Closure. Before a landfill opens, operators must have plans in place for closing it.
Owners must submit plans for monitoring gas, collecting leachate and preventing the
cover from being disturbed for 30 years after the last waste is dumped. Even before a
landfill is opened, owners have to prove they have the financial capacity to keep the site
safe after it is closed. The regulations require operators to set up a trust fund or arrange
some other mechanism as financial assurance of payment of the post-closure costs.
The cost of complying with these new landfill standards is estimated to be between $20 and $40
per ton, and will more than double the cost of landfilling in the United States.15
5.1.4 Technical Guidelines: Denmark
The "Guideline for Landfilling" issued by the National Agency for Environmental
Protection is the prime basis for landfilling in Denmark. This guideline outlines all of the major
issues of landfilling in terms of items to consider. Very few specific rules are presented in the
document and the intention is to allow for (and encourage) technical developments in meeting
specified criteria. Topics included in this guideline are as follows:
1) Laws, related laws and authorities involved.
2) Definition of waste types, typical densities, definition of landfill types, and waste types
accepted on three types of landfills.
3) Siting criteria for landfills.
4) Preliminary site investigations: geology, groundwater, surface run-off, noise, traffic,
future use of the completed landfill.
5) Liners (clay, plastic) including criteria, installment and quality control.
6) Leachate collection including expected amounts of leachate, drainage systems, pipelines
and leachate storage. No guidance is given on leachate treatment
7) Gas controls including typical amounts of gas, gas composition and gas venting. No
guidance is given on gas extraction and utilization.
8) Final use including topography, top layer size and quality, planting and maintenance.
9) Landfill operation covering working instructions, public service and safety instructions.
10) Environmental monitoring and controls including control of arriving waste, leachate
monitoring, groundwater quality monitoring, surface water monitoring, noise monitoring,
reports to the environmental authorities, inspections and monitoring after completion of
the site.16

Carl Bartone, "Institutional and Management Approaches to Solid Waste Disposal in Large
Metropolitan Areas," in the journal entitled Waste Management and Research (1991), number
9, pages 525-236.
This paper examines a model of decentralized solid waste collection and centralized
transfer and disposal that is in place in Norfolk, Virginia U.S.A. and which is being
applied in the Federal District of Mexico City. Lessons are drawn for the application of
such a model to metropolitan areas in other developing countries.
Carl Bartone, "Keys to Success: Private Delivery of Municipal Solid Waste Services," in
Infrastructure Notes, a publication of the Infrastructure and Urban Development Department in
the World Bank, August 1991, Urban No. UE-3.
Evidence in Latin American cities demonstrates that private delivery of municipal solid
waste services can be successful in terms of efficiency and quality of service. Keys to
success include creating contestable markets, establishing appropriate regulations and
standards for contractors, and strengthening local government capacity to negotiate
contracts and monitor performance.

Carl Bartone, Luiz Leite, Thelma Triches and Roland Schertenleib, "Private Sector Participation
in Municipal Solid Waste Service: Experiences in Latin America," in Waste Management
and Research (1991) 9, 495-509.
This article summarizes four cases studies on the private provision of municipal solid
waste services in four large Latin American cities (Buenos Aires, Caracas, Santiago, and
Sao Paula). This research supports the authors thesis that private service provision can
be successful in terms of cost containment and quality of service as long as the service
contracts are awarded through a competitive bidding process. These and other studies
in the region suggest that local authorities should establish operational and environmental
regulations and standards to guide private contractors, and have the capacity to oversee
these activities. Supervision and payment should be based on specific performance
measures.

1-15, U.K., World Bank Joint Library, February 1993.
This paper examines both formal and informal sector waste management operations in
Calcutta. It is hypothesized that there may not be measurable economies of scale in
waste collection, transfer, and disposal and therefore, it may be worthwhile to improve
and expand the informal system of waste management.

Cuillerso Yepes and Tim Campbell, Assessment of Municipal Solid Waste Services in Latin
America, The World Bank, Technical Department, Infrastructure and Energy Division, Urban
and Water Unit, Latin America and the Caribbean Region, June 25, 1990.
This survey of selected cities in Latin America documents solid waste practices and
policy, highlighting the managerial, and financial shortcomings of local governments on
the one hand, on the other, the positive experiences recorded so far among private
providers of service. The trend toward decentralization of responsibilities to local
governments heighten these concerns. It underscores the risks of environmental damage
and calls for extensive institution-building and improved regulations.
