Production of biogas from renewable energy sources connects to both national and regional climate and energy objectives. The regional objectives for 2020 are e.g. 80 % renewable energy sources and 15 % renewables in the transport sector.
Pre-treated food waste is one of the substrates for the biogas plant and that links to a national milestone for year 2018, indicating that at least 40 percent of food waste from households, shops and restaurants should be treated biologically, so that nutrients and energy are utilized.
The main objective with this project was to demonstrate a cost effective system for optimized energy utilization of all available biological waste material suited for anaerobic co-digestion at a sewage water purification plant with existing digester.
