The document discusses the Centre des Technologies Agronomiques (CTA) and its expertise in innovative anaerobic digestion technologies to produce biogas from agricultural and industrial waste in a more efficient manner. CTA provides feasibility studies, design, and engineering services for anaerobic digestion systems using their novel anaerobic filter technology that reduces digester size and energy losses. Contact information is provided for CTA's managing director and laboratory.

2. FIELDS OF EXPERTISE AND
INDUSTRIAL TARGETS
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
