Lab’InSight « Biomass to Energy » - CTA, December 11th 2012»

Fields of Expertise • Innovative anaerobic filter digester to produce biogas in a very

short retention time, smaller digester volume, lower energy losses and less storage time.

• Recovering of the thermal energy to heat greenhouses used for hydroponic cultures growing on the digestates.

• Irrigation of plantations comprising willows, poplars and miscanthus by residual waters

Industrial application fields • Feasibility Studies (from 10 to 1200 kWel) and demonstration • Conception and design of anaerobic filters • Conception and design of regular-type digesters
