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.


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.

Establishing Biogas-Powered Cold Storage in Rural India for Methane Mitigation and Sustainable Food Systems (2023)

Mitigating post-harvest food loss can result in economic benefits for farmers, increase food security, and reduce methane emissions from organic waste. An estimated 30 percent of food produced in India is lost or wasted, despite the country ranking 94th out of 100 on the 2020 Global Hunger Index (Bagai, 2020). Almost half of post-harvest food losses in India are attributed to the lack of a reliable cold chain, the integrated network of refrigerated storage facilities, transportation, and merchandising technologies that maintain food quality moving from harvest to the consumer (Peters et al., 2019). Cold-chain technologies are energy intensive and typically powered by fossil fuels. In recent years, there has been a focus on clean energy powered cold-chain solutions, including renewable energy powered cold storage facilities that store commodities immediately after harvest.

Naucalpan, Mexico Waste Characterization Study (2019)

In March 2017, the U.S. Environmental Protection Agency – as a lead partner in the Waste Initiative – conducted a waste characterization study at the municipality’s transfer station. The study indicated that approximately 69% of the waste handled at the transfer station could be recycled or otherwise diverted from the landfill, and that more than half of the waste could be used as feedstock in composting or anaerobic digestion projects. The municipality is using the results of the study to inform decision making about the project design and procurement options.

Solid Waste Emissions Estimation Tool (SWEET) (2022)

SWEET is a free Excel tool created by the Waste Initiative. SWEET helps users scope emissions sources such as waste collection and transportation, open burning, landfill gas collection systems, organic waste management projects, waste handling equipment (e.g., bulldozers), and waste incineration facilities. It estimates waste sector emissions including methane, black carbon, and several other pollutants. It also evaluates emissions reduction benefits of multiple alternative waste management scenarios.

Landfill Gas Screening Tool (LFG-ST) (2021)

The Landfill Gas Screening Tool’s goal is to assist cities in assessing the potential feasibility of a landfill gas energy (LFGE) project. It provides a preliminary estimate of how much landfill gas (LFG) a site could collect, and whether that fuel supply is likely sufficient to support a modest-sized LFGE project. LFGE project types include combusting LFG directly to produce heat (e.g., for industrial applications), using LFG to generate electricity, and - in some cases - converting LFG into a compressed natural gas (CNG) to fuel vehicles.

Introducing WasteMAP: A New Tool to Track and Reduce Waste Methane Emissions

29 February 2024, Virtual

Until recently, methane emissions from landfills and waste have flown under the radar, and their contribution to the climate threat has largely eluded public awareness. As methane emissions have become more visible with advanced satellite and airborne remote sensing technologies, the waste sector’s ability to address methane emissions has been hindered by a lack of accessible data, actionable best practices, and evidence-based reduction measures. The Rocky Mountain Institute (RMI) and Clean Air Task Force’s Waste Methane Assessment Platform (WasteMAP) addresses these shortfalls by providing an open-source platform that brings together measured, modeled, and observed emissions data with decision support tools and recommendations for policymakers, landfill operators and other stakeholders to develop effective strategies for managing emissions from the solid waste sector.

The webinar will take place on 29 February at 10 a.m. EST (UTC -5) to learn more about the new platform, see a live demo of the tool, and find out how RMI and CATF are supporting decision makers on the ground through country engagement.

The webinar features opening remarks by Carolina Urmeneta, Waste and Circular Economy Program Director for the Global Methane Hub, who will discuss the importance of reducing methane emissions from the waste sector.
