AD adds up

摘要

High energy prices in the region of ￡250,000 (?300,500) a year meant that, for Cannington Enterprises-a family owned company located at Swang Farm in Somerset, UK-addressing electricity bills became a priority. In 2008 the company received planning permission to build an anaerobic digestion (AD) plant and, in 2009, broke ground on the facility. An initial two digesters were installed, followed by a third six months later. The plant was using corn silage from the farm as feedstock, in addition to a small quantity of liquid waste.
