Vendor Directory:

Develop Agricultural Biogas Recovery Systems

A^star

The AgSTAR Program produces this Vendor Directory to
assist livestock producers and others involved in
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 a biogas recovery
system, we recommend you use the Vendor Directory in
combination with the AgSTAR Handbook (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 other 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 Vendor Directory is not all inclusive. We will update
the Vendor 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 Vendor Directory, or
want to update any information, please visit:
www.epa.gov/agstar/contact.html.

The information in this Directory was provided by the
listed organizations, and EPA does not guarantee the
accuracy of the information. Inclusion in this Directory
does not imply endorsement of any listed organization.

greenhouse gas (GHG) emissions reduction projects; issuing carbon offset credits generated from such projects; and tracking the
transaction of credits overtime in a transparent, publicly- accessible system. The Reserve's Livestock Project Protocol and
Organic Waste Digestion Protocol allow for the generation of credits by projects that install new biogas control systems to digest
livestock manure, MSW food waste, and certain other agro-industrial wastewater streams. There is also a version of the Livestock
protocol for use in Mexico, and one under development for Canada.

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 livestock entities, and food waste. Their 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
their 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 the client.

Sage Metering, Inc. manufactures high performance NIST Traceable Thermal Mass Flow Meters for digester gas, biogas, and
landfill gas. The popular Sage Prime Flow Meter is easy to install and provides a display of instantaneous flow rate, totalized flow
(consumption), and temperature; as well as 4-20 ma outputs of flow rate, pulsed outputs of totalized flow, and modbus®
communication. Sage has many unique features and diagnostics, such as an in situ "field zero calibration check" that takes only
one minute to check the sensor's performance, to verify that the sensor is clean, and to assure that there is no shift or drift in the
flow meter. In addition, the Sage technology has tremendous sensitivity with negligible pressure drop, and hence can detect
extremely low flow rates, typical of landfill gas and biogas applications. Sage Flow Meters feature a turn down of at least 100 to 1
with resolution of 1000 to 1.
