Anheuser-Busch has installed anaerobic wastewater pretreatment systems or {open_quotes}Bio-Energy Recovery Systems{close_quotes} (BERS) at six breweries in the U.S. The primary purpose of BERS is the removal of soluble organic matter (grain liquor, waste beer, cleaning solutions) from wastewater in order to reduce the impact on downstream treatment works, either privately or publicly held. A byproduct of the anaerobic process is biogas (75% methane) which is used in the plants` boilers to create steam. A history of Anheuser-Busch`s wastewater management philosophy is discussed including the adoption and refinement of various treatment methods. A case study is presented, demonstrating by way of an energy balance the savings realized by BERS installation. Finally, the environmental benefits of these projects are displayed in a life cycle analysis.
