Biogas Sector

The GMI Biogas Subcommittee focuses on building capacity within Partner Countries to leverage common interests across the areas of agriculture, municipal solid waste, and municipal wastewater. These interests include biogas energy use, the types of wastes managed, waste treatment technologies, and the potential for synergistic projects involving input streams from multiple sources. Efforts include developing and promoting tools, policy guidance, and project development resources at the national, state, and city level within Partner Countries.

GMI Technical Groups

Within the Biogas Sector, GMI maintains active technical groups in the areas of agriculture, municipal solid waste (MSW), and municipal wastewater. These groups provide international leadership to mitigate global methane emissions through the abatement, recovery, and use of methane. They promote collaboration between delegates from Partner Countries and Project Network members to build capacity, develop strategies, and expand opportunities for using methane as a renewable energy resource.

Agriculture

Methane emissions come from livestock enteric fermentation, livestock waste management, rice cultivation, and agricultural waste burning.

Municipal Solid Waste

Municipal solid waste management and treatment activities such as landfilling and anaerobic digestion are sources of methane emissions worldwide.

Municipal Wastewater

Methane is produced when the organic material in municipal wastewater decomposes anaerobically.

Biogas Done Right - Introduction (2019)

Jorge Hilbert explains and introduces the importance of biogas in the agricultural sector, while additionally explaining biogas’s potential for increasing future energy efficiency and technological sustainability.

Using Animal Manure as a Resource (2019)

Anaerobic digestion, or AD, is the biological process that breaks down biological materials like compost or manure into biogas. Livestock manure accounts for 3 percent of man-made methane emissions globally. Methane, when captured and stored, can be used to generate electricity and heat, or it can be processed into natural gas fuel. By capturing the biogas, we are also preventing the release of methane, one of the most potent greenhouse gases, to the atmosphere.

Methane Mitigation Matters: Climate Change (2015)

Methane is a prevalent manmade greenhouse gas that traps 28 times more heat than carbon dioxide (CO2). Reducing methane emissions by recovering and using methane as a clean energy source offers many benefits for the environment and local communities. This video highlights the many ways that reducing methane can benefit the environment and local communities.
