Republic Services and Clean Energy Sign Renewable Biomethane Recovery Agreement

Leading solid waste operator Republic Services, Inc.

has signed a renewable biomethane recovery agreement with Clean Energy Fuels Corp.

to process and sell renewable natural gas recovered from Republic's Sauk Trail Hills Landfill site in Canton, Michigan. Clean Energy will build a high-BTU landfill gas processing plant at Republic's Sauk Trail Hills Landfill, which will produce renewable natural gas for injection into the natural gas pipeline system. The renewable natural gas will be distributed for vehicle fuel use to Republic natural gas fleets, Clean Energy customers and direct use by renewable power customers. The agreement provides Republic a beneficial use for landfill gas, and will also provide Republic with conventional natural gas vehicle fuel for use in Republic's growing natural gas fleet. When the landfill-gas-to-energy processing facility is fully operational, output of clean, green bio-methane is expected to equate to 6 million diesel gasoline gallon equivalents annually. Production is expected to begin in early 2012. Republic also, under other agreements, contracted Clean Energy to build, operate and maintain 14 compressed natural gas (CNG) refuse vehicle fueling stations and to provide Republic liquefied natural gas (

) refuse fleets in California with approximately 3 million gallons of LNG vehicle fuel per year.
