In 2014 the Environmental Protection Agency (EPA) classified landfill gas as a cellulosic biofuel, a step that some industry analysts believe could blossom into a biogas gold rush. With this biofuel classification, landfill operators began leveraging assets to tap into a new market: Renewable Identification Numbers (RINs) credits.
RINs are serial numbers assigned to batches of biofuel for the purpose of tracking its production, use and trading. The credits are often purchased by oil companies, that buy them to meet certain investment thresholds on the percentage of gas produced from renewable sources.
