Republic Services, Aria Energy, BP launch RNG ops at Memphis area landfill

US waste collection and recycling company Republic Services Inc (NYSE:RSG) said that a renewable natural gas (RNG) facility set up at its South Shelby Landfill in Memphis, Tennessee, has started operation.

The landfill gas-to-RNG project stems from a partnership between Republic, renewables company Aria Energy Corp and oil-and-gas major BP plc (LON:BP).

Aria, which operates the project, processes the landfill gas, or biogas, and purifies it into RNG. BP is tasked with transporting the RNG into the interstate natural gas pipeline grid and marketing it to renewable energy customers.

The South Shelby facility is Aria and BP’s fourth RNG project at a Republic Services landfill. It has the production capacity of 4,000 MMBtu per day and can produce the equivalent of nearly 33,250 gallons of gasoline daily.

Low-carbon RNG is an upgraded, methane-rich product that can be used to fuel natural gas vehicles, which in turn results in around 50% lower greenhouse gas emissions compared to equivalent gasoline or diesel-fuelled vehicles, Republic said.

The recycling company is committed to sending 50% more biogas to beneficial reuse by 2030. Currently, it is involved with 69 landfill gas projects across the US.
