About the Mapping Tool Data
A hybrid collection of data layers shows AD projects, composters, waste management facilities, growth potential for AD in the agriculture sector, investments made into renewable energy projects, and various types of state incentives and programs that affect the AD industry. A brief description of the data is provided below.
- Anaerobic Digestion Projects on Livestock Farms in the United States: As of January 2014, AgSTAR estimates that there are approximately 239 anaerobic digester systems operating at commercial livestock farms in the United States. Projects that are under construction or have been previously shut down are also shown. Details about projects can be reviewed by clicking on a map symbol and in-depth profiles are available for select projects.
- Landfill Gas Energy Projects in the United States: Creative uses of LFG landfill gas (LFG) include heating greenhouses, producing electricity and heat in cogeneration applications, firing brick kilns, supplying high–Btu pipeline quality gas, fueling garbage trucks, and providing fuel to chemical and automobile manufacturing. Projects range from small–scale community driven initiatives to multimillion dollar private investments. Data for operational LFG projects were compiled from a database managed by the EPA’s Landfill Methane Outreach Program.
- Wastewater Treatment Plants in the United States: There are thousands of wastewater treatment facilities in the United States. Many of those facilities operate anaerobic digestion systems to generate energy from biogas and to control emissions of greenhouse gases. Biogas flow from these digesters can be used as fuel to generate reliable electricity and heat for the facility.
- Waste Facilities: Locations and other details for nearly 9,000 waste facilities are available from this map. Data were provided by the Waste Business Journal, which tracks and maintains business information about a variety of waste processing and disposal operations. Details for each facility, categorized into 10 types of facilities, include the types of wastes or materials that are accepted, volume of primary waste, cost per ton, tipping fees, and remaining capacity.
- Composting Facilities: Composting facilities divert organic wastes away from traditional landfills. This map provides details for operating and pilot composting facilities across the United States, including the annual tonnage and number of households served by each. Facilities are organized by the types of waste being received.
- Anaerobic Digestion Project Opportunities: Biogas recovery systems at livestock operations can be a cost-effective source of clean, renewable energy that reduces greenhouse gas emissions. Because of its high energy content, biogas can be collected from manure and used to supply on-farm energy needs. The results of AgSTAR’s Market Opportunities Report (June 2010) are used to represent the number of candidate farms and biogas energy generation potential by state for swine and dairy operations.
- Inventory of Livestock Survey (USDA, 2007): There is great potential to use anaerobic digestion systems to generate renewable energy from livestock operations in the United States. Recent and evolving improvements in anaerobic digestion technologies and project approaches increase the feasibility of building anaerobic digestion systems to serve farm- and community-scale needs. This map presents state and county level data for the number of livestock operations and the number of animals for cattle, chickens, and hogs.
- Methane Emissions by State and Animal Group: EPA develops the Inventory of U.S. Greenhouse Gas Emissions and Sinks to track annual U.S. emissions and removals by source, economic sector, and greenhouse gas going back to 1990. EPA uses national energy data, data on national agricultural activities, and other national statistics to provide a comprehensive accounting of total greenhouse gas emissions for all man-made sources in the United States. This map presents state-level summaries from the Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2011 for livestock operations, including beef, dairy, poultry, swine, sheep, goats, horses, mules and asses, and bison.
- Renewable Portfolio Standards (RPS): A Renewable Portfolio Standard (RPS) provides states with a mechanism to increase renewable energy generation using a cost-effective, market-based approach that is administratively efficient. An RPS requires electric utilities and other retail electric providers to supply a specified minimum amount of customer load with electricity from eligible renewable energy sources. States may specify the types of energy that qualify for the RPS, such as biomass, wind, CSP, distributed photovoltaic, centralized photovoltaic, hydro, geothermal, landfill gas, and ocean.
- State Incentives for Renewable Energy: This map provides summaries of incentives and policies established by the federal government, state governments and U.S. territories, local governments, and larger electric and gas utilities in the United States. Incentives and policies that support renewables include financial incentives (tax incentives, grants, loans, rebates, industry recruitment/support, performance-based incentives, green building incentives, etc.) and rules, regulations and policies (public benefits funds, renewable portfolio standards, net metering, interconnection standards, solar/wind access policies, contractor licensing, equipment certification, solar/wind permitting standards, building energy codes, energy standards for public buildings, etc.).
- State-level Investments in Renewable Energy Projects: The map contains information regarding USDA programs that provide assistance to renewable energy and energy efficiency projects. The energy investment data is summarized by state.
- USDA Investments in Renewable Energy: The map contains information regarding USDA programs that provide assistance to renewable energy and energy efficiency projects. Energy investments are categorized by energy type, including anaerobic digester, energy efficiency, geothermal, hydroelectric, hydrogen, renewable biomass, solar, and wind. Investments are also shown by funding program.
- Related Organizations: Through its Partner program, AgSTAR collaborates with state agencies, agricultural extension offices, universities, and other state-wide non-governmental organizations to promote the planning, deployment, and long-term success of anaerobic digester projects. Additionally, colleges and universities that conduct research related to anaerobic digestion systems are also included on this map.
