“An anaerobic digester is an air tight, oxygen‐free container that is fed an organic material, such as animal manure or food scraps. A biological process occurs to this mixture to produce methane gas, commonly known as biogas, along with an odor‐reduced effluent. Microbes break down manure into biogas and a nutrient‐rich effluent.”
How Organic Waste is Recycled
Anaerobic digestion is a collection of processes where microorganisms break down biodegradable (think food waste) material in the absence of oxygen. At Energy Recyclers location, the anaerobic digestion process is used for to further sustainable agriculture, recycle biodegradable waste and produce electricity.
Anaerobic digestion occurs naturally in some soils and other natural environments. The Anaerobic digestion system at our location in Pennsylvania benefits the environment by capturing the gases released in decomposition of biodegradable products and using those gases for electrical generation. Anaerobic digestion often reduces the emission of landfill gas into the atmosphere.
Anaerobic digestion is widely used as a source of renewable energy. The process produces a biogas, called methane. This biogas can be used directly as fuel, in combined heat and power gas engines. The nutrient-rich digestate also produced can be used as fertilizer.
