 Problem / opportunity 

• Treatment of effluents resulting from the production of apple jams
• Regulatory obligation to purify effluents:
•  156,000 m3 / year
•  540 Tons COD / year

Solution:

• Methanisation of effluents using VALBIO METHACORE® technology – 1 digester of 750 m3
• Eventually, the objective is to use the biogas produced on a boiler to produce hot water
• In service since September 2012

 Results of methanisation:

• 280,000 m3 of biogas produced per year
• 1,500,000 kWh / year
• Purification efficiency:
• COD: 90%
• BOD: 90%.
