The Magic Factory
• Biogas plant with capacity:
60 000 t food waste
50 000 t animal manure
• Started operation 2015
• Owned by Greve Biogass
(Municipality of Tønsberg)
• Operated by Lindum
• Upgraded biomethane
serves 80% of the buses in
the region
• Low treatment cost
• Manure inclusion improves process and reduces GHG emmissions
from the area greatly
• Integrated teaching centre for communicating the green shift…
• Second stage for WWTP sludge initiated

Lindum R&D strategy in 2011:
• Natural ecosystems as model for newdevelopment
• Away from the fossil
• Save energy
• Reduce climate impact
• New products only based on waste
• Biology rather than chemistry
• Solve several challenges at once by demonstrating concrete integrated solutions for waste, energy and food production
Why is food production not sustainable?
Conventional food-web
CO2 CH4 N2O
Nutrient run-off, and 24 000 000 000
tons of soil
Water loss through
evaporation
