The whole Project: To promote the nutrient cycle of the local food systems and the nutrient neutrality of the municipalities. Luke's part: Nutrient recycling and energy production will be managed by biogas process. The operation of the biogas plant in Palopuro agroecologigal symbiosis will be documented.
The result will be exact knowledge how different feed materials affect to the energy production and the quality and storing of the process residue. Results are based on experience and measurements. The whole chain from the raw material in the field to the biogas plant and back to the field will be under examination. It is expected that the yields will get better by using the residue as a fertilizer. A part of the methane will be used for heating and the most of it will be sold as traffic gas.
