What MONTAUK RENEWABLES INC does
Montauk Renewables is one of the largest U.S. producers of renewable natural gas (RNG), developing, owning, and operating facilities that convert biogas from landfill gas and anaerobic digested gas into RNG for transportation and renewable electricity. The company secures long-term biogas feedstock through agreements with landfill and agricultural sites, then processes the biogas into sellable products while capturing valuable environmental attributes like Renewable Identification Numbers (RINs) under federal and state renewable initiatives. Operating a portfolio of 11 RNG and two renewable electricity projects across seven states, Montauk views agricultural waste from livestock farms as a significant growth opportunity.
