Solid manure is a poorly used resource in Sweden but by anaerobic digestion this can be change. It has the potential to contribute with 1 TWh biogas/year. Furthermore, nitrogen is largely in organically bound form but by digestion it´s directly plant available nitrogen form, ammonia, will be multiplied.
In today's use of solid manure in agriculture, its potential is only partly used. Digestion of solid manure means that it can generate considerably more goods. The overall aim and goal of the projects within this area is to, in large scale biogas plants, identify and test technology and system solutions for substrate mixtures with mostly solid manure, also including its digestate handling and use. It is also included to demonstrate that these digestion processes can be operated efficiently.
The work within this area has been divided into two projects:
Co-digestion of solid and liquid manure
Region Kalmar County, Region Uppsala, Region Östergötland
Project 1: Mönsterås Biogas, Promill Teknik AB, Linnéuniversitetet , Project 2: Gasum, More Biogas, SLU Egendomsförvaltningen, Länsstyrelsen i Kalmar Län samt SLU, institutionen för energi och teknik
