Where there's muck there's gas

German company Schwarting-Uhde teamed up with the Stuttgart-based Fraunhofer Institute for Boundary Layer Research and Biotechnology (IGB) to develop a novel process for energy and fertiliser recovery from organic waste and sewage sludge.
IGB project leader Walter Trosch was presenting the achievements of the 'Schwarting-Uhde Process' in Pollutec's German pavilion.
Schwarting-Uhde last year commissioned a new energy and fertiliser recovery plant near Dresden. The plant consumes 95kt/a of a 50:50 mixture of manure and organic waste.
Out comes dried matter with fixed ammonia as a fertiliser (which goes directly back to the farmers who supply the manure) and biogas which generates electricity at a rate of 13kJ/m3.
