Glossary
Anaerobic digester: A solid waste management facility that uses microbes to break down manure from a dairy or feedlot into biogas and sludge. In the E3 BioFuels-Mead system, anaerobic digestion takes place in two four-million-gallon concrete vessels.
Biogas: A product of the anaerobic digester that is a combination of methane, carbon dioxide and trace levels of other gases produced by the decomposition of organic matter.
Whole stillage: The unprocessed by-product of ethanol production, consisting of protein, oils and cellulosic fiber.
Thin stillage: The waste portion of whole stillage; mixed with manure in the E3 BioFuels-Mead anaerobic digester to increase the efficiency of biogas production and make use of the corn cellulose it contains.
Wet distillers grain: Also known as WDG or "wet cake," the portion of whole stillage that is fed without drying to cattle on site. If not dried, the high-moisture wet distillers grain can spoil quickly, and is very costly to transport.
