Problem / opportunity:

• 15 million bottles / year
• Regulatory obligation to purify effluents:
• 12,000 m3 / year
• 80 Tons COD / year

Solution:

• Methanisation of effluents using VALBIO METHACORE® technology – 1 digester of 50 m3
• Biogas valorized in a boiler to produce hot water
• Aerobic finishing treatment
• In operation since 2010

Results of methanisation:

• 135,000 m3 of biogas produced per year
• 800,000 kWh / year
• Purification efficiency:
• DCO: 90% DBO: 90%
