WELTEC BIOPOWER, a company which manufactures biogas, will present its anaerobic digestion plants for industrial and municipal use at the IFAT trade fair for environmental technologies, held in Munich, Germany, from 4 to 8 May 2020.

The reference projects for the digestion of waste and the production of biomethane, which is equivalent to natural gas, include the WELTEC plant of the French potato chips manufacturer Altho, whose chips brand ‘Bret‘s’ accounts for one third of the French market. Every year, the plant in St. Ge´rand, Brittany, produces about 1.75 million standard m3 of biomethane from 22 000 t of production waste in the form of potatoes and starch as well as sludge from the internal wastewater treatment plant.

Altho benefits greatly from the biomethane production, which enables it to use its leftovers in a sustainable manner and cut greenhouse emissions. The annual savings amount to approximately 3 900 t of CO2 equivalent.

WELTEC has implemented process technology for the energy plant. The mix of solid and liquid substances is first pre-processed and homogenised in order to ensure efficient digestion in the stainless-steel digester. The entire process is fully automated and controlled by a PLC unit. With the help of the membrane processing, the biogas is then transformed into biomethane.
