The Performance Partnership Grants will be made up of funds which would otherwise be awarded as categorical grants; states will have the option of combining two or more grants into one application and one workplan, that may be used to implement pollution prevention strategies, and to address multi-media whole facility, sector, and community objectives. The new grants program places greater reliance on environ- mental and programmatic self-assessments by each state, giving states more flexibility to meet a limited number of agreed-upon environmental goals and performance measures. Pending passage of authorizing legislation, all states and tribes will be eligible to apply for the grants in 1996.

IN MEMORIAM EPA lost a champion of pollution prevention with the sudden death of Jim Craig, a Branch Chief in EPA’s Pollution Prevention Divi- sion. Jim died of liver cancer on May 26th. Jim began his career with EPA in 1984 as a statistician for the Office of Solid Waste. Jim Craig was known for his calm demeanor, superior judgment, superb management skills, and sense of humor. His friends at EPA and in the pollution prevention field will miss him very much. ------- 3 Fbllution Preventicsi News May-June 1995 AGRICULTURE IN SEARCH OF... PARTNERS FOR SAFER PESTICIDES E PA has launched its first pesticide voluntary partnership for pollution prevention. The Pesticide Environ- mental Stewardship Program (PESP), is dedicated to protecting human health and preserving the environment by reducing both the use of pesticides and the risks associated with pesticide use. The partner- ship is a key element in the PESP, which is sponsored by EPA, USDA, and FDA. Current partners (listed in box on this page) include agricultural growers as well as non-agricultural interests, such as utility companies who use pesticides on their right-of-ways. Partners in PESP agree to develop and implement an environmental stewardship plan tailored to their own pesticide usage. They also agree to use the safest, most effective pest management practices available. In turn, EPA provides a liaison to assist the partner in developing comprehensive, achievable goals. Liaisons also act as “customer service representatives” for EPA, providing the partner with access to information and personnel. EPA also promises to integrate the partners’ stew- ardship plans into its agricultural policies and programs. EPA has also provided some grant dollars to some of the charter partners. So far, grower groups have committed to a number of projects, including conduct- ing more research into 1PM techniques, developing computer prediction models for more precise pesticide applications, educating their members and the public regarding pesticide use, and working with equipment manufacturers to fine-tune application techniques. Examples include: ‘ The American Corn Growers will be promoting and expanding its “bottom- line” corn growing contest, which seeks o’ to maximize a grower’s profit from corn production while reducing production inputs such as pesticides. ‘ The California Pear Growers and California Pear Advisory Board are funding — through grower and proces- sor check-offs — the Pear Pest Manage- ment Research Fund and research into safer pest management techniques. The California Citrus Board has committed $750,000 to research into safer pest control. A consortium of East Coast and Midwest utilities is training their pesticide users in techniques to lower risks from pesticide application. PESP was announced in December 1994 and grows out of the commitment made by EPA, USDA and FDA in joint testimony before Congress in September 1993 to develop commodity-specific initiatives to reduce the use and risks of pesticides. EPA is currently pursuing partnerships with a number of interested organi- zations as well as beginning the “supporter” phase of PESP. A supporter is an organization that does not use pesticides, but has a significant influence over pest management practices. Food processors, for example, may influence the use of pesticides on produce they buy, even though they do not apply pesticides to the produce themselves.

YARD CARE SEMINARS DRAW HOMEOWNERS A ppealing to homeowners pride in their lawns has brought success to a water quality program in Virginia. The Cooperative Extension Service of Prince William County wanted to teach homeowners ways to conserve water, fertilizer, and pesticides in caring for their yards, but found that few citizens would attend a pollution prevention seminar. Nearly everybody wants to prevent pollution, but “it’s hard to get people to make time in their busy schedules,” says extension agent Marc Aveni. But now that the extension service delivers the same messages in informal seminars on pruning, land- scaping, and the like at local parks and community centers, the turnout is much better. Aveni says the seminars show homeowners that preventing pollution does not, mean sacrificing an attractive yard. “We need to have realistic expecta- tions,” he says. Citizens who are willing to keep records of their yard care to add to statistics on pollution prevention can “volunteer” their yards for individualized advice from the extension service’s trained volunteers. Media coverage of this part of the program has attracted many more participants, Aveni says. More than 500 people have participated in some aspect of the program. Similar programs are underway in Wisconsin, Florida, Washington state, and other places. and many others are in development. For more information on Virginia’s program, call (703) 792-6285. VIDEOS TEACH TRICKS TO SAVING WATER, FERTILIZER Vegetable growers can learn how to save on fertilizer costs and protect ground- water with the help of two videos from the California Department of Food and Agriculture. The how-to video, “Drip Irrigation and Fertigat ion Management of Vegetable Crops,” shows how with careful monitor- ing, growers can give crops just the right amount of fertilizer and water through drip irrigation. Half of the U.S. vegetable supply is grown in California’s coastal valleys, often using intensive farming techniques to produce two or three crops a year. While crops like lettuce, broccoli, and cauliflower thrive with fertilizer adding nitrogen to the soil, overuse of fertilizer and over-i rrigation threaten the area’s groundwater supply. The other video, “Best Management Practices for Nitrogen and Water Use, ’ is a more general overview intended to build awareness of the problem of excess nitrogen in groundwater. Both videos include reference booklets and can be purchased for $20 each from the Fertilizer Research and Education Program, California Department of Food and Agriculture, 1220 N Street. Sacra- mento, CA 95814. For more information. call (916) 653-5340. MAKING THE MOST OF MANURE Livestock farms are saving money while becoming less . . . shall we say, aromatic, thanks to a program called AgSTAR. The voluntary program, a component of President Clinton’s Climate Action Plan, s based on a computer model that shows the economic value of capturing the methane naturally produced by manure. By covering over the lagoons of water where manure is stored on livestock farms and using other techniques to maximize anaerobic digestion of manure, methane can be captured in storage tanks and used for farm energy needs, such as refrigeration or heat. In addition, odors and greenhouse gases in the atmosphere are reduced and surface and groundwater are protected. AgSTAR, a joint program of EPA, USDA, and the Department of Energy, helps farmers determine which methane recovery and use technologies would work best for them, and develops financing sources to help with start-up costs.

Some 70 percent of the bay’s suspended solids and phosphorus and much of its nitrogen come from non-point sources. These sources include fertilizers, pesti- cides, and erosion from feed crop fields on the 400 dairy farms of the East River watershed north of Milwaukee. The East River ultimately feeds into Green Bay. In 1991. the U.S. Department of Agriculture and the University of Wiscon- sin Extension began funding a three-year integrated crop management 1CM) demonstration project for the 2 19-square- mile area. Farms that volunteered for the project were required to follow an erosion management plan and had their soil testt cl using newly developed techniques to determine exactly how much fertilizer they needed. Participating farmers were encouraged t plant legumes, which enrich the soil with nitrogen they take from the air, thus reducing the need for chemical fertilizer. They were also advised on how to spread manure more efficiently, and with better timing, on the fields that would benefit most from it, again to reduce the use of chemical fertilizer. Crop consultants visited the demonstra- tion farms every week to monitor pest populations. Pesticides were used only if they judged the cost of crop losses to be greater than the cost of using the pesticide. As a result of these efforts, the program has prevented the application of 10.5 tons of rootworm insecticide and 3,000 tons of fertilizer over three years. Farmers saved four to five dollars for each dollar invested, with the average participating farm saving $15,000 over three years. Not surprisingly, 80 percent of the demonstration farms are continuing to practice 1CM even after the end of their three-year commitment, and each year more farms ask for training in 1CM techniques. “1 sit down with farmers one- on-one at their kitchen table and show them how to do this,” says Kevin Erb, a nutrient management specialist with the Brown County Extension office. “Farmers are learning they can t afford to farm without 1CM.’ For more information, contact Erb at 414i 391-4610.

Also, some paper products could be made from plants that are harvested annually rather than from trees that take decades to regrow.

In Minnesota. for example, the 1994 Governor’s Awards for Excellence in Pollution Prevention were given to seven companies that are succeeding in prevent- ing pollution. One winner was Roger’s Auto Body Shop. Roger’s began distilling solvents for reuse in 1984. Despite in- creased business since then, Roger’s has reduced the amount of solvents used from 400 barrels to three barrels per year. Improved painting equipment has helped reduced the amount of paint used by almost 50 percent, and has reduced the amount of volatile organic compounds released into the air by about 50 percent. “Not only have the expenditures caused very significant waste reduction, they have repaid themselves in savings and continue to save us dollars,” said Roger Lindemann of Roger’s Body Shop. In Ohio, the Eighth Annual Governor’s Awards for Outstanding Achievement in Pollution Prevention recognized five organizations for efforts ranging from reducing yard waste to comprehensive pollution prevention in truck manufactur- ing. The Hamilton County, Ohio Depart- ment of Environmental Services—Solid Waste Management District (SWMD was recognized for its efforts toward total recycling of yard waste. SWMD’s “Just Mow It” program uses education to encour- age mulching and composting. The County also has a voluntary agreement with waste haulers and with landfill operators not to accept yard waste. Yard waste is collected separately through private haulers or is taken to collection sites. The material then “We hope that because of the publicity we have received other programs will view composting yard waste as a resource as much as a pollution prevention activity,” said Christine Hitchcock, SWMD’s Public Affairs Coordinator. The 1995 effort already has begun, utilizing television, newspaper, radio and billboards to disseminate infor- mation about the program. Another Ohio winner, truck manufac- turer Navistar International Transporta- tion Corp., instituted several successful pollution prevention efforts including changing the types of paints used, thereby reducing volatile emissions from paints and solvents by 50 percent and saving approximately $3.5 million per year. The Texas Governor’s Awards for Environmental Excellence are awarded in eleven categories, including agriculture, government, media, and large and small businesses. Connecticut encourages businesses not only to be good environmental citizens, but also to operate with a positive environ- mental impact. The 1994 Governor’s Awards for Environmental and Economic Progress were awarded in the categories of Pollution Prevention, Recycled and Earth- Friendly Products, Environmental Service, Manufacturing and Environmental Leadership. In Iowa, the state awarded the Governor’s Waste Reduction Awards in the categories of large manufacturer, small manufacturer, and non-manufacturer. The three winners eliminated 6,000 tons of solid waste and 13 tons of volatile air emissions and saved more than $300,000. lo ir’s Aut.

The reason so many boxes are avail- able is that most boxes are used only once and then disposed. Over 90 percent of all U.S. consumer, wholesale and industrial products are transported in corrugated boxes. Corrugated boxes accounted for 24 million tons of garbage in 1990. UPDATE FROM EPA’S 1994 MSW REPORT: MORE WASTE, BUT MORE RECOVERY EPA’s has issued the 1994 update of The Characteristics of Municipal Solid Waste in the United States. Highlights include: The United States generated 207 million tons of MSW—4.4 pounds per person, per day. After recovery, recycling and composting, discards were 3.4 pounds per day. The 1993 recovery rate of materials for recycling and composting was 22 percent, up from 17 percent in 1990. Of the remaining waste, 16 percent went to combustion facilities and 62 percent went to landfills or was otherwise disposed. Between 1990 and 1993, recovery and composting increased from 38 million to 45 million tons. Recovery of paper and paperboard ac- counted for over half of the increase, followed by yard trimmings. ‘ EPA anticipates that, for the first time, per capita generation of MSW will decrease to 4.3 pounds per person per day by the year 2000. EPA bases this projection in part on source reduction efforts, especially removing yard trimmings from the waste stream by composting or leaving cuttings on lawns. Even with the source reduction efforts, total MSW is expected to increase to 218 million tons in 2000. If a 30 percent recovery for recycling and composting is reached, discards to landfills and combustion will decline from 162 million tons in 1993 to 152 million tons in 2000. The percentage of MSW landfilled has declined from 83 percent in 1985 to 62 percent in 1993. Even with continued reductions in waste, landfihling will be the dominant method of disposal in 2000. The 162-page report (EPA 530-R-94-0421 is available for $27 from the National Technical Information Service at 703-487-4650. The Executive Summary (EPA 530-S-94-042) is available free from the RCRA Hotline at 1-800-424-9346. oI That’s a lot of boxes and a lot of waste— and a lot of potential for waste reduction. A recent report published by INFORM, Inc.. addresses the need to reduce this waste source. DeliLvring the Goods: Benefits of Reusable Shipping Containers, written by David Saphire, examines the real costs of disposable shipping materials and provides examples of companies that have lowered their costs and reduced their waste stream using reusable containers. Whether made out of plastic and used 250 times or made of reusable cardboard and used five times, large and small companies in a variety of industries can dramatically reduce waste by eliminating single-use containers. Over the course of its lifetime, a two cubic foot plastic, reusable shipping container making 250 trips will replace 250 single-use cardboard boxes, reducing waste by 98.5 percent and costs by up to 92 percent. Other benefits of reusable containers include reduced shipping damage due to sturdier contain- ers and reduced labor costs associated with assembling and breaking down single use boxes. Obstacles to reusables include higher initial cost, the need to return containers, and storage of containers. Reusable containers are being used successfully in a variety of industries, including produce, soft drinks, high tech, and auto manufacturing.

Logically, if a product has less packaging, the cost of production is less and the waste generated when the product is used is less, benefiting both the consumer and the environment. Yet, according to a recent article in Warmer Bulletin, pub- lished by the World Resource Foundation, the issue of waste and packaging is not as simple as it may appear. Take toothpaste, for example. Tradi- tional toothpaste packaging—an alumi- num tube inside a cardboard box—is often considered wasteful. The aluminum tube is used because it protects the contents and is flexible enough for the tube to be squeezed. However, the flat ends and sharp corners of metal tubes can damage or even puncture other tubes in shipping and handling. In addition, tubes are hard to stack on store shelves. The cardboard box solves both these problems. This double packaging is rendered unnecessary by the use of plastics. Plastics are flexible and strong and can be used in place of metal here. Because the plastic tubes do not punc- ture each other, and the tube has a wide cap that allows the _______________ toothpaste to sit _____________________ on the shelf by — itself, the card- board box is unnecessary. The use of aluminum and cardboard is completely eliminated. Reducing the use of aluminum has environmental benefits, since mining and smelting aluminum are environmentally damaging and energy intensive. However, the manufacture of plastic from finite oil reserves also has environmental impacts. Further, neither the plastic tubes nor the aluminum tubes are recyclable. Al- though aluminum itself is recyclable, a discarded toothpaste tube has residual toothpaste inside, a coating of paint or lacquer on the outside, and may have plastic screw threads, making it inappropriate to be mixed with aluminum cans or foil. Similarly, the plastic tubes also contain residual tooth- paste and are made of a composite of plastics, making even a clean tube difficult to recycle. Another consideration is the size of the tube. Larger containers generally provide more product in proportion to packaging, assuming that all the product in each package is used up. Studies of tooth- paste packaging done by the Cornell Waste Management Institute at Cornell Univer- sity in 1994 and reported in Warmer Bulletin, found that with larger containers, more product re- mained in the package and was QUANTITIES OF MUNICIPAL SOLID WASTE 1980 AND 1990 (kg/inhabitant) 1980 2226 313 524 260 Country Austria Belguim Canada France Germany Greece Italy Japan Luxembourg The Netherlands Norway Portugal Spain Sweden Switzerland United Kingdom USA 1990 320 343 601 328 3 18 296 348 408 448 497 472 287 3223 374 441 398 803 (3 1988 1978 348’ 259 249 355 351 489 416 214 270 302 351 319 723 1 Situation before 3/10/1990 (2) 1989 4)1987 5 1982 6 1979 SOURCE: Warmer Bulletin, Feb. 1995. wasted. Because proportion- ately more product was used from the smaller containers, the advantage of larger contain- ers is lessened. This contradicts most assumptions about package size. Which way to go? When all is said and done, Warmer Bulletin predicts that the trend toward shorter, fatter stand-up tubes without boxes will help improve the proportion of toothpaste used and reduce the amount of wasted product and packaging. ------- 10 I 1Iution Prevention News May-June 1995 TECHNOLOGY TECHNOLOGIES FOR TOMORROW T he latest in new technologies for industrial applications were unveiled at the Department of Energy’s Innovative Concepts Fair held in Denver in April. This was the seventh Innovative Concepts fair, which showcases, and in some cases awards seed funding to, innovators that have developed, but not yet fully commercialized their technolo- gies. Below are several examples, selected at random, from among the 50 or so technologies displayed. THE COPPERLOK TM BONDING PROCESS Boats and ships have an ever-present accompaniment: marine growth that can accumulate on the bottom of vessels in layers more than 6 inches, causing a drag on their speed and increasing the amount of fuel they must use. Also, marine-based oil platforms, power plants, and other industries must spend considerable effort protecting inlet surfaces from contamina- tion and clogging caused by marine growth. For centuries, people used copper as an “anti-fouling” protector for wooden hulls. But with the introduction of steel and fiberglass hulls, the use of copper became impractical and other methods were used, including toxic paints. These paints, however, contain VOCs and toxins that are hazardous to humans and sea life, and are being sharply restricted by EPA. Copperlok TM Systems located in Culver City, CA has come up with an updated use of copper for anti-fouling purposes. The innovation is a copper alloy coating process that allows the bonding of thick metal coatings to many different metallic and non-metallic materials. A base coat is applied which uses resin that contains tiny hollow spheres. After being abraded, the base coating exhibits a rough outer surface with millions of nooks and crannies. Then a final metal coat is applied using a metalliz- ing spray gun. Copper, copper alloy, or copper-nickel wire is released and becomes embedded in the nooks and crannies, thus developing strong mechanical links be- tween the base coat and final coat. The application should last for up to 10 years, and eliminates the usual need for hauling, paint removal, and repainting every 2 to 3 years.

RECYCLING RINSE WATER AND CLEANING SOLUTIONS Rinse water from industrial cleaning processes is one of the largest waste streams that companies have to deal with. Some companies have tried reverse osmosis membrane water separation and purification systems, but the membrane surfaces typically get fouled with oil, organic films that slows down the membrane’s flow rate. Even water-based cleaning processes — an improvement over solvent-based processes — increase the waste water volume and end up producing sludges that must be landfilled. Custom Process Systems in Pasadena, TX has developed a process that allows rinse water and cleaning solutions to be recycled indefinitely. The first stage uses a combination of ozone and electrolysis to oxidize oils and greases that have been left in cleaning solutions. The oxidation process converts them into polar water- soluble surfactants that can be reused in the same cleaning process.

The membranes do not foul because they are reconcentrat- ing a regenerated cleaning solution that is essentially free of oil and grease. As the cleaner is reconcentrated in the reverse osmosis membrane, it actually cleans the membrane. All of the rinse water and cleaner can be continuously reused. The only waste produced by the process is a very small amount of precipitated inor- ganic solids, which can be rendered nonhazardous or even recycled if they contain heavy metals such as lead. Custom Process Systems believes the new process will reduce the amount of water and chemicals needed to maintain the cleaning process. significantly reduce energy consumption, and eliminate waste disposal costs. The concept could have wide potential in commercial and defense sectors. (Contact: Michael P. McGinness, tel: 713-941-0907; fax: 713-868-2332.) COORS USES UV TO CURE CANS Traditional methods of decorating the 100 billion aluminum cans that are produced annually used solvent-based coatings that released significant amounts ot of VOCs and hazardous air pollutants into the environment. A widely-used current method is the water-based “high solids coating” which contains less solvent but still results in VOC emissions. The Coors Brewing Company has developed a can printing technology in partnership with several other compa- nies, which boasts significant environ- mental, energy, and cost benefits over currently avail- able technologies. The technology uses ultraviolet Mandrel (UV) light to cure Wheel the decorative image on the Can exterior of Transfer aluminum Unit beverage cans, rather than curing the cans in a gas-fired oven. Separate UV “fountains” supply the ink to rollers, which coat individual plates. The plates, one for each color used, are raised positive images of the graphic design to be printed on the cans. Clean cans are fed into the printer and placed on a rotating steel mandrel; in rotating the can body against the rotating blanket, the graphic image is transferred to the can. The cans are transported to the UV oven for curing with UV light. The entire process is very fast: printing speeds are about 1600 to 1800 cans per minute, and the oven cure time is about 0.7 seconds. Overall energy costs are significantly lower for the IJV curing than for conventional thermal technology if air emission controls are factored in, and fewer VO(’s are emitted.
