Biogas as a source of renewable energy obtained from the recovery of food industry waste

Abstract

Biogas produced by the anaerobic digestion (AD) process is cheap and offers the possibility of treatment and recycling of a variety of residues and agricultural by-products, various biowaste, organic wastewater from industry, sewage, and sewage sludge, in a sustainable and "friendly" way with the environment. At the same time, biogas brings a large number of socio-economic benefits, both for farmers directly involved in its production and for society as a whole. For all these reasons, biogas resulting from AD processes is one of the main priorities of the European strategy on biofuels and renewable energy.
