Apsley Farm is an innovative farm located in southern England, in an area without livestock and where soil is poor in organic matter. The company has therefore decided to use the digestate produced by the biogas plant to enrich and feed its cultivated fields. In fact, crop rotation is practiced on this farm, where the production of energy-rich crops to feed the biogas plant are alternated with food crops. This system not only makes it possible to produce clean energy, but also to keep the soil rich and prevent the production of bacteria harmful to crops. Apsley Farm is a true example of a circular economy, which aims to be 100% green (today it is 97% green).
