Renewable Natural Gas Anaerobic Digestion Creates Renewable Natural Gas. Renewable natural gas is created from organic feedstocks derived from food, agricultural, and even green waste. Most of the biological sources used in our process are wet or “slurried” with dry matter in the 12 – 15% range. Biological waste emits methane gas naturally through the rotting process in the absence of oxygen. This is especially evident when organic waste is buried deep in a landfill, where it creates and releases methane into the atmosphere. In this form, it is a very damaging greenhouse gas. The difference: Instead of releasing harmful gases, we collect them as a renewable and sustainable energy source. The AD process creates “biogas”, which is a mixture consisting mostly of methane, carbon dioxide, and water vapor. Biogas can be used to fuel boilers or combined heat and power (“CHP”) systems to generate thermal or electrical energy in a “behind-the-meter” system, thus making it an excellent critical power supply. Using our proprietary technology, biogas can then be refined into “biomethane”, which is more commonly known as “renewable natural gas” (“RNG”). RNG is a valuable and natural energy product that can be injected into a pipeline or compressed into “compressed natural gas” (“CNG”) for fleet vehicles. We’re environmentally friendly. The creation and use of biogas and RNG does not release new greenhouse gases into the atmosphere and does not contribute to global climate change. In fact, bioenergy is critical in the fight against climate change because it reduces the need to extract and burn damaging fossil fuels. We keep it local. The renewable natural gas created by our facilities comes only from local organic waste sources. When choosing a location for our facilities, we look at logistically smart permitting with access to major highways, railroad connections, and even barge access. Our facilities are highly efficient and we meet or exceed all regulatory requirements on the local, state and national level. Every step of the anaerobic digestion process is constantly monitored to ensure maximum quality, efficiency, and an overall positive impact on the environment.
