Optimising the biogas process
Energy Recovery and Waste Minimization by Coupling Hydrothermal Carbonization with Anaerobic Digestion Process
Short Introductive summary
The thermal process of hydrothermal carbonization (HTC) is a promising technology for the management of wet biomass waste. This process results in two fractions: hydrocarbons, which have a high potential in the usage as fertilizer or filter material, and the fraction of process water. The process water (PW) fraction contains varying amounts of nutrients and pollutants, such as toxic phenols and furfurals. Anaerobic digestion poses a potential technology to gain energy from PW and reduce the waste stream. In a second step after AD the PW will be cleaned and thereby recovered for industry. The aim of VARESI is to estimate a circular economy system for industry coupled with HTC and AD resulting in a zero-waste economy by using all occurring product and waste fractions. Overall this data will be the basis for a mathematical model to perform different case studies, resulting in waste minimization, resource recovery and the overall reduction of treatment costs.
