Input materials
Manure, solid/liquid separated and dried to 60% DM.
Output products
Stabilised and sanitised biochar, rich in phosphorus and can be used as organic fertiliser and/or soil improver
Process description
Manure is pyrolyzed at 400-500°C under oxygen-limiting conditions in the reactor.
The reactor is kept at a slight negative pressure to prevent leakage of pyrolysis gas.
Energy efficient pyrolysis can be operated without requiring energy input if input is drier than 60%DM / 40% water
Operating status
Pilot scale plants operating in Japan on manure (capacity 720 kg/day, operating since 2012)
Demonstration plant (5 t/day) contracted for 2022, Shenyang, Chin. Full scale plant (18 t/day) under study.
