Methane (CH4) is released into Earth’s atmosphere when organic material breaks down in anaerobic conditions. This anaerobic decomposition is common in covered landfills and manure piles. Our global emissions from waste have almost doubled since 1970, and waste emissions now produce 3% of anthropogenic (human origin) emissions (IPCC 2014). About half of these emissions come from this anaerobic decomposition of solid waste on land. A 2016-2018 study by NASA’s Jet Propulsion Laboratory (in cooperation with the California Energy Commission) utilized airborne remote-sensing devices and satellites above California. The study revealed over 550 individual point sources emitting plumes of highly concentrated methane. 10% of these sources, considered super-emitters, contributed the majority of the emissions detected. The team estimates that statewide super-emitters are responsible for about a third of California’s total methane emissions.
Detrimental Environment Effects:
Methane is 80x more dangerous than carbon dioxide (CO2) for the first 20 years after it reaches Earth’s atmosphere. Over time, methane remains 25x more dangerous than CO2, because it traps far more heat and releases more energy. Therefore, curbing methane emissions is a high priority for corporations and farms.
Increased Governmental Regulation:
In October 2009, the United States Environmental Protection Agency (EPA) issued a rule (40 CFR Part 98) that requires large suppliers in the United States to report their greenhouse gas emissions. The rule’s intent is to collect accurate and timely emissions data for government policy decisions in the future. It is only a matter of time before greenhouse gas emissions become more tightly regulated by federal and state governmental agencies. California, for example, has made regulations for human-caused emissions a top priority.
Increasing Activist Pressure Directed Towards Municipal, State, and Private Industry Segments:
Many public and private sectors face enormous pressure from environmental activists, the public at large, as well as investors and shareholders to reduce greenhouse emissions. As a result, more and more businesses that generate greenhouse gases are becoming worried about their negative public image and future long-term viability.
THE SOLUTION: GENERATING BIOMETHANE AS AN ALTERNATIVE CLEAN ENERGY SOURCE
For On-Site Biogas Recovery And Upgrading
Generating biomethane from landfills, dairies, and wastewater facilities through anaerobic decomposition not only eliminates methane emissions into the atmosphere, but can also be a source of additional revenue for the operator by:
- Selling the gas to a utility through pipeline injection
- Offsetting costs associated with purchasing fuel for vehicles by producing their own fuel (Renewable Natural Gas, or RNG)
- Producing their own electricity through cogeneration
BAUER is known globally for its expertise in manufacturing gas compression systems. To provide our customers with a complete turnkey solution for generating biomethane, BAUER has partnered with highly experienced companies which are specialized in various aspects of biogas upgrading and beyond.
