New Anaerobic Digester Systems

Jordan Dairy Farm (Massachusetts)
In April 2011, the Jordan Dairy Farm in Rutland began using its new digester system to convert manure into energy. Governor Deval Patrick toured the anaerobic digester at the farm following a ribbon-cutting ceremony on May 31, 2011. AGreen Energy, LLC, a majority farmer-owned digester development entity, developed this project. Manure from the farm's 300 cows is combined with food wastes from nearby food processing plants—Cains Foods, Kayem Foods, HP Hood & Sons, and Cabot Creamery—to generate biogas. New England Organics, a division of Casella Waste Systems, is operating the facility, which has a 300 kilowatt (kW) combined heat and power (CHP) unit. The electricity produced is transferred to the grid and the heat is used to dry the residual material, which is then used as animal bedding and fertilizer. In 2007, the farm was awarded more than $80,000 from the Massachusetts Clean Energy Center (formerly the Massachusetts Technology Collaborative Renewable Energy Trust) to help construct the system that cost an estimated $3 million.

Van Erk Dairy (Ohio)
Earlier this year, the digester system at the Van Erk Dairy in Haviland became operational. The vertically mixed plug flow system (designed by GHD, Inc.) uses manure produced by the farm's 2,100 cows to produce biogas, which is being used to generate electricity with a 600 kW engine-generator set. The project was partially funded by the U.S. Department of Agriculture's (USDA's) Rural Energy for America Program (REAP), having received more than $932,000 in both grants and loan guarantees.

Kish-View Farms (Pennsylvania)
In March 2011, the new digester system at Kish-View Farms in Belleville became operational. The complete mix system, built by RCM International, LLC, uses manure from 350 milking cows to generate electricity. The manure is pumped into the digester three times a day and the resulting biogas is piped to a 100 kW CHP unit to produce heat and electricity. The new system not only offsets all of the farm's electric demand, but is also heating the farmhouse and barn. A grant from the Chesapeake Bay Foundation helped finance this project.

Landyshade Farm (Pennsylvania)
In October 2010, Landyshade Farm in Lancaster began using manure from its 700 cows to feed its new digester system, designed by RCM International, LLC. The resulting biogas fuels a 180 kW CHP unit to produce heat and electricity. Hot water and heat are used at the milk parlor, an employee trailer, and at Landyshade Farm House, an onsite bed and breakfast. Landyshade Farm has a net metering agreement with PPL Electric Utilities Corporation, which allows the farm to receive payment for the electricity generated beyond onsite needs. They are also selling the recovered digester solids as garden mulch as part of their associated mulch and topsoil business, along with using the solids as animal bedding. Team Ag, an agricultural consulting firm, provided the erosion and sedimentation control plan, the design for the manure storage facilities, and the construction inspections for this project. Funding for this project was provided the Chesapeake Bay Watershed Foundation.

Keewaydin Dairy Farm (Vermont)
In April 2011, the digester system at the Keewaydin Dairy Farm in Stowe became operational. Avatar Energy, LLC, a renewable energy company, designed and installed its AnD 1B22 system at the farm. As one of Avatar Energy's first commercial projects in the United States, the system is designed to handle manure from small farms, which in the case of Keewaydin Dairy, is approximately 75 milking cows. The system is producing more than 4 cubic feet of biogas per gallon of waste introduced into the system. This biogas is then used to fuel a CHP unit, recovering heat and more than 10 kW of electricity. The heat is used to produce hot water, which is used by the farm. Excess electricity is sold to the local power grid. The farm received funding for the project through Vermont's Clean Energy Development Fund.

Dairy Energy, Inc. (Van der Hyde Dairy) (Virginia)
Earlier this year, Dairy Energy, Inc. (Van der Hyde Dairy) in Chatham completed installation of the state's first commercially sized dairy digester system. The vertically mixed plug flow system, designed by GHD, Inc., uses manure from nearly 1,200 cows to produce biogas. The biogas is fed into a 450 kW engine-generator set to produce electricity, which is sold to Dominion Power. The digester system also reduces odor from the manure, yields clean bedding for the farm's dairy cows, and produces a more marketable form of manure for use as a fertilizer, which the dairy plans to sell. The project received a $1 million grant through Virginia's Biomass Energy Grant Program, which received funding through the American Recovery and Reinvestment Act of 2009 (ARRA).

USDA Agencies Partner to Support On-Farm Anaerobic Digester Systems

To advance digester system development, USDA Rural Development and the Natural Resources Conservation Service (NRCS) have joined efforts to deliver services and funding to farmers interested in making anaerobic digester systems part of their operations. Eligible farms, with no other contracts with NRCS, can receive up to $450,000 in financial assistance to at least partially fund 50 percent of the project costs. For one recent project, costs of the digester system components were divided nearly equally between the agencies. NRCS provided financial assistance for the digester, manure pumps, and separator, and USDA Rural Development provided a grant and low-interest loans for the electrical generation equipment, including engines, generators, and the electrical hook-up.

Outreach Events

On March 24, 2011, AgSTAR's National Program Manager, Chris Voell, presented at the Regional Technology Summit for the Farm Pilot Project Coordination in Annapolis, Maryland. His presentation, "Nutrient Capture Potential Following Anaerobic Digestion," explained the market opportunity to advance anaerobic digester systems. Benefits include diversified revenue, rural economic development, conservation of natural resources, and production of renewable energy and "green" co-products. The next generation of digestion (as well as co-digestion) systems could create a multi-billion dollar industry for agriculture-based energy, nutrients, and value-added products. Case studies were provided as examples of successful business models. Dane County, Wisconsin's, Cow-Power centralized digester systems are some of the first to explicitly address nutrient transport, water quality, and phosphorus reduction. The first Cow-Power system, installed in the town of Vienna, serves three primary farms and was developed by Clear Horizons, LLC. It has a generation capacity of 2 MW and innovative phosphorus removal technology that removes 60 to 70 percent of the phosphorus in the manure. The project was so successful that Dane County is planning to build a second digester system in the town of Springfield. For more information, read Chris Voell's presentation (PDF) (35 pp, 3.2MB).

On March 31, 2011, AgSTAR attended the On-Farm Biogas Workshop in Harrisonburg, Virginia, a one-day workshop sponsored by the Virginia Cooperative Extension. Participants discussed integrated nutrient management; high-solids digester systems; commingled waste streams; the Cove Area Regional Digester in Martinsburg, Pennsylvania; and the Van der Hyde Diary biogas system in Chatham, Virginia. Presentations are available on the workshop website.

Policy Updates

In April 2011, a new California law took effect that requires public utilities to obtain one-third of their electricity from renewable sources. Governor Edmund G. Brown, Jr., signed the legislation (PDF) (64 pp, 365K), which increases California's current 20 percent renewable portfolio standard (RPS) target in 2010 to 33 percent by December 31, 2020. Biogas from anaerobic digester systems is an eligible renewable resource under the state's RPS and could contribute significantly to meeting the new RPS target. AgSTAR estimates that anaerobic digester systems are feasible at 889 dairy farms in California, based on the analysis in its Market Opportunities report. These farms could produce 2,375,000 MWh of electricity and reduce 342,000 tons of methane per year. This new legislation makes California's renewables standard the highest in the United States.

California's Central Valley Regional Water Quality Control Board has proposed for consideration at the June 2011 Regional Board Meeting a General Order regulating the permitting process for centralized dairy manure anaerobic digestion or centralized dairy manure co-digestion facilities. The proposed requirement addresses the permitting process for centralized facilities using two types of feedstock—dairy manure and mixed manure and other organic wastes—as well as the land area where the resulting wastes are applied. Under the proposed General Order, all digester effluent must be applied to cropland for nutrient recycling in accordance with a comprehensive nutrient management plan prepared by a certified nutrient management planner. This nutrient plan must address both dairy and centralized digester system nutrients.

On May 11, 2011, Indiana's Governor, Mitch Daniels, signed a bill that provides incentives for utilities to participate in a voluntary Clean Energy Portfolio Standard (CPS). A participating electricity supplier must meet three criteria to qualify for an incentive; suppliers may own or purchase clean energy credits to fulfill these criteria. The bill, SB 251, sets a goal for 10 percent of the state's electric generation to come from clean energy sources by 2025; it also includes an amendment that calls for at least 50 percent of the energy produced by Indiana utilities participating in the CPS to come from within the state.

Progressive Dairyman Highlights Biogas Market Opportunities
In March, Progressive Dairyman published an article highlighting the findings of AgSTAR's report Market Opportunities for Biogas Recovery Systems at U.S. Livestock Facilities (PDF) (41 pp, 11 MB). AgSTAR estimates that 8,200 U.S. dairy and swine operations could support biogas recovery systems, and that these facilities have the potential to collectively generate more than 13 million MWh per year and displace about 1,670 MW of fossil fuel–fired electricity generation.

Report Highlights Opportunities for Biogas on California Dairy Farms
A new report published by the California Center for Cooperative Development titled Challenges and Opportunities for California's Dairy Economy (PDF) (149 pp, 6.4MB) identifies anaerobic digester systems as one way for dairies to become more profitable, but also acknowledges that significant barriers must be overcome before the economic promise of biogas systems can be realized. One chapter of the report is dedicated exclusively to dairy biogas facilities and discusses various cooperative models that can be used to drive growth in the sector, including utility cooperatives, cooperatively owned digester system facilities, and the supportive efforts of California's largest dairy co-ops. The report also addresses the energy policies needed to support the sector, various types of existing and novel biogas technologies, and the economic benefits of turning a waste stream into a source of revenue. Finally, an appendix lists key national stakeholders in the dairy biogas sector (including AgSTAR) and provides short case studies of existing projects in California.

2011 U.S. Greenhouse Gas Inventory Report

Chapter 6 of the report focuses on the agricultural sector and includes a discussion of emissions from manure management, as well as the emissions reductions attributed to the capture and destruction of methane at facilities using anaerobic digester systems.

Wisconsin Bioenergy Initiative Report on Biogas Opportunities
In March 2011, the Wisconsin Bioenergy Initiative (WBI) released a strategic plan, The Biogas Opportunity in Wisconsin (PDF) (64 pp, 5.4MB). A collaboration of researchers, business leaders, policymakers, and industry experts created this plan to encourage investment in biogas energy opportunities in Wisconsin. The report focuses on the benefits of overcoming the challenges of increasing biogas production in Wisconsin and the United States. The tool is designed to facilitate discussions with policymakers on transiting from fossil fuels to biogas and biomass as primary sources of power. For the WBI, next steps include a statewide education and outreach effort and working with policymakers on actions to assist in business development.

Energy Center of Wisconsin Publishes Food Industry Biogas Casebook
In March 2011, the Energy Center of Wisconsin published the Great Lakes Region Food Industry Biogas Casebook (PDF) (55 pp, 3.46MB), which discusses how food and beverage producers have been using anaerobic treatment of their production wastewaters to produce biogas for decades. The Energy Center examined 12 facilities in Illinois, Indiana, Minnesota, New York, and Wisconsin to provide snapshots of performance. Profiles include facilities operated by Anheuser Busch, General Mills, Kraft Foods, and others. The report illustrates that as energy costs increase, the biogas produced through anaerobic digesters provides a cost advantage for the facilities profiled in this new report.

New Paper Examines Air Issues from Animal Agriculture
A new issue paper from the Council for Agricultural Science and Technology, "Air Issues Associated with Animal Agriculture: A North American Perspective," is now available. The paper delves deeper into the air quality issues associated with animal agriculture. Experts from six universities examined a large amount of data and focused their information and conclusions around swine, poultry, dairy, and beef operations. Their critical analyses look at a wide scope of air issues, from odor and gas emissions, including greenhouse gases, to particulate matter associated with manure and animal management. The paper also highlights the economic implications of air emissions, mitigation technologies being employed to decrease aerial pollutants, and EPA's efforts to monitor emissions.
