More profitable biogas production by optimization of anaerobic waste digestion

VTT Technological Research Centre of Finland (VTT) coordinates a new European project, which focuses on studying anaerobic digestion (AD) of organic waste and developing its control. AD process can be optimized to produce either biogas or volatile fatty acids that are even more valuable products than biogas. The produced volatile fatty acids can be converted further to raw materials with which it’s possible to produce oil-replacing biobased products, such as bioplastics. During the anaerobic digestion process, which contains four main steps, the organic matter is degraded by bacteria to
