Biochar-Boosted Biomethane
Coupling woody-biomass pyrolysis with anaerobic digestion
PROVEN · 3 PLANTS RESTORED (2025)Partners: PowerUP (biomethane) · CHARWOOD
Input
- Woody biomass → pyrolysis
- Manure (sheep, cattle, poultry) · agro-food
Process
- Pyrolysis + anaerobic digestion, 14% biochar dosing
Output
- Biomethane (grid / bio-CNG)
- Process heat for digester & drying
- Digestate + biochar fertiliser
Key benefits
- +40% methane production with 14% biochar in feedstock
- Each biomass to its best route: woody → pyrolysis, wet → digestion
- Pyrolysis heat keeps digesters warm; biochar earns carbon credits
+40%methane yield
14%biochar in feedstock
