Republic Services, Aria Energy expand US landfill gas project

Republic Services and Aria Energy have expanded the landfill gas-to-energy (LFGTE) project at County Line Landfill in Indiana.

The facility, which began operating in 2014, has expanded to 7.6 MW from 6 MW, increasing its biogas use by 25%.

Aria developed, owns, and operates the LFGTE project at Republic Services’ County Line Landfill. Electricity generated from the project is sold to Wabash Valley Power Alliance under a long-term power purchase agreement.

The expanded County Line LFGTE facility is capable of generating enough renewable energy to power more than 4,800 area homes annually.

“Last year, Republic Services set a long-term sustainability goal to send more than 50% more landfill gas to beneficial reuse by 2030,” said Pete Keller, vice-president of recycling and sustainability at Republic Services. “The expansion of the LFGTE project at County Lane Landfill is a key milestone in helping us meet that goal.”

Based on US Environmental Protection Agency (US EPA) calculations, the expanded County Line LFGTE project prevents carbon emissions equivalent to the consumption of more than 43 million gallons of petrol annually.

The US EPA estimates that 7.6 MW of energy produced from landfill gas reduce emissions by more than 44,000 tons of CO2 per year.

Richard DiGia, president and CEO of Aria Energy, said: “Utilising low-carbon biomethane sources such as landfill gas reduces greenhouse gas emissions and helps improve local air.

“This project expansion furthers our commitment to producing clean, renewable electricity and natural gas to homes and businesses across the US.”
