It describes the current waste methane ecosystem, outlinesthe diverse benefits of waste methane investments, and explores key methanemitigation technologies including AD, LFGTE, and black soldier fly (BSF). Across thesetechnologies, we prioritize AD and LFGTE investments because they are better suited toprivate finance deployment at scale. The waste sector is a major and under-addressed source of methane emissions,accounting for approximately 20% of human-caused methane globally. Mature andproven technologies like anaerobic digestion (AD) and landfill gas to energy (LFGTE) arereadily available and widely deployed in developed markets although adoption inemerging economies has been slow. Many project developers in these markets cite difficulties accessing capital. Despitedemand for capital,lack of credible bankable projectslimits its supply. Only $6.1billion was invested in waste methane mitigation in 2021/22, well below the $20 millioninvestment need. Most projects fail to meet the investment criteria for capital providerslike revenue certainty, risk allocation, and scale, often resulting from poor feedstockquality, weak policy and regulatory frameworks, and operational challenges. Our analysis indicates a sizeable investment opportunity for private FIs in Latin Americaand Southeast Asia to support and capitalize waste methane mitigation. Across Brazil,Chile, Colombia, and Mexico, which represent 75% of regional solid waste methaneemissions, an annual investment of $2.3 billion and $7.3 billion is needed by 2030 and2050respectively. Across Indonesia, the Philippines, Vietnam, Thailand, and Malaysia,which collectively accounts for 95% of the region’s solid waste methane emissions, $1billion and $3 billion in annual investment is needed by 2030 and 2050, respectively.
