Background
• Landfill gas (50% CO2 and 50% CH4) is created as Municipal solid waste (MSW) decomposes in a landfill
• MSW landfills are responsible for 17% of human-related CH4 emissions in the U.S.
• At the same time, CH4 emissions from landfills represent a lost opportunity to capture and use as a significant energy resource

Concerns
• It takes decades (even centuries) for waste to decompose in traditional landfills (“dry tombs”)
• Extensive monitoring / maintenance is required• Long-term liability and financial burden• A concern to today’s operators and a problem to
future generations• Bioreactor landfills – A modern-day solution

• Optimizing moisture and other environmental conditions to stimulate waste decomposition
• Organic wastes in landfills can be rapidly degraded/ made less hazardous
• Landfill gas can be generated rapidly – more feasible as a renewable energy source
• Waste volume can also be reduced more rapidly – offering landfill extended service life

• Using septage as an augmentation agent • Why septage?
– Readily available in many communities– Typically unwelcomed by WWTP– Land application leads to surface water contamination– Promotes organic decomposition through
• Moisture addition• Microbial seed addition• Nutrient addition• pH regulation

• Municipalities have access to low interest rate (2.5%) State Revolving Fund (SRF) loans to complete drinking/ wastewater improvement projects.
• The CWSRF typically don’t fund a landfill project. However, since the septage bioreactor landfill project will eliminate run-off due to land application of septage and reduce the need to treat septage at local wastewater treatment facilities, funding can be granted.
Teaming / Funding Outlook
![Page 37: Accelerated Landfill Energy Recover Technology](https://reader035.fdocuments.in/reader035/viewer/2022062813/5681660e550346895dd94f60/html5/thumbnails/37.jpg)
• Partnering municipalities can implement similar projects to provide solutions for ongoing groundwater contamination issues, help increase site life, or generate additional renewable energy production.
• Since payback on the loan is over 20 years, municipalities are offered a way to generate additional cash flow through renewable energy sales, and fund the capital expense over time – a win-win situation.
