       ENERGY AND POLLUTION PREVENTION

-------
                 INDUSTRY DIRECTORY FOR ON-FARM
                 BIOGAS RECOVERY SYSTEMS
The AgSTAR Program  produces this Industry
Directory to  assist livestock producers  and
others  involved in the  developing anaerobic
digestion  systems  to  identify   consultants,
designers, developers, equipment vendors, and
other providers of biogas energy services.

If you  are  in the  planning stages of project
development,  we recommend that you use the
Industry  Directory  in   combination  with  the
AgSTAR Handbook (which is  available on the
AgSTAR website  at  www.epa.gov/agstar)  as
project development tools  to  begin the  initial
project  planning   process  to  increase  the
potential for success.

Commodity  Organizations  represent  the
interests  of  a  specific  crop   or   livestock
commodity. Commodity  organizations generally
are involved in marketing or lobbying activities.

Consultants  provide  a  variety  of  services
related to biogas  recovery systems, including
feasibility analyses (e.g.,  technical, economic,
and financial), nutrient  management planning,
system design, and environmental impact and
regulatory assessments.

Developers design and install biogas  recovery
systems  for  livestock and  other industries. In
many   cases,  these   are  "turn-key"  system
developers who provide consultant services as
part of the development package.

Financing specialists provide  loans for biogas
projects,  funding on-farm  biogas systems  for
profit,  and brokering the  sale of carbon offsets
and renewable energy certificates.

Energy Service Providers are  independently
owned,  municipal  or co-operative electricity or
natural gas companies that have an interest in
providing biogas energy to customers.
Manufacturers/distributors include entities that
manufacture,  distribute,  and  in  some cases,
install  equipment  used  in  biogas   recovery
systems,  including covers,  engines, tanks,  and
system components.

Publishers distribute journals and  reports of
interest to farm owners and others interested in
biogas recovery systems.

Universities   are   educational   institutions,
including  land grant colleges and universities,
involved in  developing  and demonstrating on-
farm biogas recovery systems and technologies.

The Directory is not all inclusive. We will update
the Directory  regularly as we learn of  new
businesses in the livestock waste market. These
updates will be posted on the AgSTAR website,
along with other AgSTAR products.

If you wish to be included in the Directory, go to
http://www.epa.gov/agstar/tech/form.html.  If you
currently are on the list and want to update any
information, go  to  http://www.epa.gov/agstar/

Approximately 50 of these systems treat agri-waste from food-related processing, while the remaining systems treat brewery,
beverage, and chemical wastes. Each of these systems involves biogas collection and flaring or utilization (in most cases via
burning in a boiler to produce hot water and steam). In several instances,  utilization has involved cogeneration.

AgriClean, LLC designs and installs biogas systems in the U.S. and abroad. Although there are a number of waste treatment
technologies in its portfolio, AgriClean is a licensee of a patented fixed-film AD system from the University of Florida.
Examples of biogas systems include: 1) A fixed-film digester on a swine finishing farm that produces 30,000 animals per year
(around 1600 animal units (AU) at steady-state) near Greenville, NC in partnership with the Animal and Poultry Waste
Management Center of NC State University; 2) A fixed-film digester and biogas use system on a 400 head (around 560 AU)
dairy in Hillsboro, MS in partnership with the Mississippi Alternative Energy Enterprise; 3) A fixed-film digester and biogas use
system on a swine farrow-to-finish operation that produces 64,000 animals per year (around 3580 AU at steady-state) in
Canada, and; 4) An in-ground ambient temperature earthen digester and biogas use facility on a 4000 head swine nursery farm
in Montpelier, MS. AgriClean also acts as a project developer on numerous animal waste and food waste projects, including a
biogas plant and piping system  at a 1,000 head per day beef processing facility in Mississippi. AgriClean has also designed a
unique "power-flush" system (AgriJet Patent Pending) that will reduce the total amount of water used to flush the barns by close
to 70%. This means that manure collected from barns is close to 6% solids as opposed to the 0.7% that exists today, making
any treatment system significantly more cost-effective.

We are in Kwazulu-Natal, South Africa. We do Projects in South Africa as well as other parts of the continent. Being innovitave
leaders in the field we design and construct the cheapest and most cost effective biogas plants in the world. So much so that it
would be cheaper for an interested party from the USA to import our digesters and CHP plants and our expertise than it would
be for an American Firm to design and construct one. We  have done Farm digesters, and are consulting on a city project at the
moment. We also fully utilise the methane produced in the farm project and bottle it and run tractors and utility vehicles on
excess methane. We have constructed the cheapest commercial biogas plant on the planet using boiler litter.

Biothane specializes in biological treatment of industrial wastewater, and designs and builds anaerobic digesters for livestock
manure. Biothane worked with E3 BioFuels, LLC to develop an integrated cattle manure management/ethanol project in Mead,
Nebraska that is expected to revolutionize ethanol production by virtually eliminating the need for fossil fuels.  Biothane
designed a nutrient recovery that separates the effluent waste stream into two separate streams, one high in solids and
phosphorous, which is well-suited for composting, and the other low in solids and high in nitrogen, which will be sent to an
ammonia stripping column, with aqueous ammonia as a final  product.

The proposed Resource Development Associates biorefinery includes a locally managed system comprised of a 20-million
gallon/year ethanol plant that uses local crops and an adjoining 28,000-head confined cattle feedlot connected to an anaerobic
digester. Independent contractors will run "backgrounding" operations with additional 13,000- to 15,000-head of cattle. The
complex will produce fuel-grade ethanol, finished cattle, biogas, and biofertilizers. The biorefinery is economically attractive,
with an estimated internal rate of return of approximately 30 percent, achievable through significant economies of scope. A
commercial demonstration of this referenced biorefinery is undergoing final detailed engineering and project development at a
site located outside of Pierre, South Dakota. Construction is scheduled to commence late spring of 2002 and start-up is
scheduled for the summer of 2003.

Capstone manufactures microturbines that can burn biogas with as little as 35 percent methane content. The currently available
biogas model is a 30-kW microturbine that was initially offered for natural gas, propane, oil field waste gas, and diesel. During
early 2000, a demonstration test program was conducted with Los Angeles County Sanitation Districts at Puente Hills landfill
and at Palmdale wastewater treatment plant. Successful testing during 2000 led to commercial operations at 20 biogas
facilities, as of March, 2002, using a total of 117 Capstone microturbines. The Capstone microturbine achieves a combustion
efficiency of 99.999 percent. The patented premix combustion system is uniquely designed to reduce emissions of NOx, CO,
and hydrocarbons to extremely low levels.

US Energy Services (USES) provides design/build services for the construction of and/or ownership of clean energy power
generation systems. The industries served include, but are not limited to landfill gas, waste water treatment facilities,
agriculture and live stock entities, and food waste. Our design/build projects typically combined the design and construction
process into a single contract, which results in better Client control, expedited construction, reduced costs and faster return on
investment. For our build-own-operate projects this allows USES to reduce its internal construction cost which in turn enhances
the "no out-of pocket" program by supplying energy at a reduced cost to our Client.

LO-CAT is an H2S removal technology, where we use liquid iron redox to reduce hydrogen sulfide from gas streams (some as
high as 99%), to pipeline specification (less than 1 ppm in some instances). This process is safe, uses non-toxic chemistries,
proven (we have over 170 units worldwide), and very cost-effective (LO-CAT removal of H2S generally costs between $0.10 to
$0.15 per pound of sulfur recovered), and is probably most effective in the 500 pound per day to 20 long tons per day (of sulfur
recovered). We have several operating LO-CAT units in biogas environments, as well as in odor control (in similar
environments). We do have solid media technologies in our possession (similar to iron sponge), but the economics of LO-CAT
generally far outweigh these types of processes (in most cases). In addition to LO-CAT, we are in the final process of coming
out with a technology called mini-CAT (which will target applications with less than 500 pounds per day of sulfur), which is
based upon LO-CAT technology, but on a much simpler, smaller scale. This technology will operate with the same success of
LO-CAT, at a sulfur recovery cost of approximately $0.35 to $0.45 per pound of sulfur recovered (the higher cost is due to
different solid sulfur filtering technologies, which makes for a "wetter" cake in mini-CAT, and therefore, a relatively higher
chemical demand rate). This cost level is still very much less than aerobic iron sponge, which generally operates at levels of
$1.15 to $1.25 per pound of sulfur recovered. By the way, when we talk about sulfur recovery...the sulfur that is formed in the
LO-CAT or mini-CAT process is solid, elemental sulfur, that is very suitable as an agricultural adjunct.  We are truly a "green"
technology, as we remove a toxin from the air, promoting the removal of a harmful greenhouse gas (methane),  in a completely
safe environment, producing a product that is very desired by the agricultural industry. In addition to sulfur removal, we have
several  other unique gas processing technologies.

The Workplace Health and Safety Program provides technically-based training and technical assistance services to assist
management, labor, and medical and legal professionals in putting scientific and technical information to practical use in
resolving work environment problems. We provide public and on-site courses and workshops for management, labor  unions,
and the public, serving approximately 2500 students per year with instruction. An even greater number of people are potentially
reached through technical assistance. Examples of technical assistance services available are: on-site hazard evaluation
including job hazard analysis, process failure analysis, overall workplace vulnerability assessments, and indoor air
investigations; guidance for medical surveillance and periodic screenings; assistance in selection of engineering controls,
administrative controls, protective clothing or equipment; and assistance in product or process substitution to reduce workplace
hazards. The Program publishes health hazard manuals, fact sheets, and technical articles. Both training and technical
assistance services are available on the safety and hazard assessment of farm digesters, including the manure handling
system, anaerobic digester, and biogas handling system. Two hazard assessment documents  developed for digester systems
are available at the Cornell University Manure Management Program website:
