RENEWABLE NATURAL GAS When organic waste is sent to landfill, it decomposes and releases methane, a potent greenhouse gas. Anaerobic digestion is a process that converts organic waste under controlled conditions into bio-methane, which can be purified to become renewable natural gas. Greenfield works closely with partners, suppliers, and municipalities to find ways to convert municipal and industrial waste into renewable natural gas — addressing two vexing societal problems at the same time. LEARN MORE ABOUT OUR PROJECTS: SEMECS In collaboration with municipal partners, we have developed a large-scale anaerobic digester adjacent to our Varennes ethanol plant to convert organic waste into biogas (methane and CO2). The enterprise is known as Société d’économie mixte de l’est de la couronne sud (SEMECS). This project will remove 40 000 metric tons of organic waste each year from local landfills. The biogas is piped into Greenfield’s ethanol plant, thereby significantly lowering the carbon intensity of the ethanol produced. ADVANCED ANAEROBIC DIGESTION TECHNOLOGY In Chatham, Ontario, we are developing a new advanced anaerobic digestion (AD) technology that accelerates the process of turning waste into renewable natural gas and hydrogen. Greenfield’s patented technology accelerates the AD process, and can handle a much higher organic loading rate than conventional anaerobic digestion systems, thereby producing bio-methane with less energy, and with a smaller footprint than traditional AD systems.
