Republic Services, a non-hazardous solid waste operator, has announced that it has entered into an agreement with Clean Energy Renewable Fuels, a supplier of natural gas fuel for transportation in North America, for recovering renewable biomethane from its landfill in Tennessee. Landfill gas is a natural byproduct of decomposition.
The North Shelby Landfill is located in Millington, Tennessee. The recovered landfill gas is to be used by Republic Services for its increasing number of natural gas-powered vehicles. The present agreement is the second of its type between the two companies. The first relates to Republic's Sauk Trails Landfill in Canton, Michigan. The recovery at this site is expected to commence in September 2012.
As part of the agreement, Clean Energy Renewable Fuels will be responsible for building the high-BTU plant required for processing the landfill gas and then supplying it to the US natural gas network. Landfill gas has numerous uses, including industrial applications, renewable power and as fuel for vehicles.
The North Shelby Landfill plant is expected to produce renewable natural gas fuel equivalent to around 4 million gallons of diesel fuel, every year. The estimated 4 million diesel gallon equivalents in the first year are expected to grow to 5.7 million diesel gallon equivalents annually within the first 10 years. The production from the first year is expected to cater to around 260 trucks for a year. The production of the landfill gas is likely to commence in the latter part of 2013.
When compared to gasoline or diesel fuel, renewable natural gas that has been derived from landfill biogas is more environmentally friendly and generates nearly 88% fewer greenhouse gas emissions.
