Transcript of Centre des technologies agronomiques -HE Charlemagne - Lab'InSight Biomass to Energy

  • 1. 1 Centre des Technologies Agronomiques Haute Ecole Charlemagne, Stre Prof. Christian Marche Managing Director CTA LabInSight Biomass to Energy - CTA, December 11th 2012

2. 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 2 FIELDS OF EXPERTISE AND INDUSTRIAL TARGETS Stre December 11th 2012 3. 3 METHANISATION = Energetic and Environmental Valorization of agricultural and industrial effluents Stre December 11th 2012 4. 4 METHANISATION Strictly anaerobic pH : 6,5-8 Opt .T: 4OC or 55C C/N= 16-19 !!
