An adaptable and tailor-made offer for the supply, analysis, expertise, assistance and operation of your digestion facilities.
SEDE operates a territorial digestion site at Graincourt les Havrincourt, built by Veolia : Artois Méthanisation.
SEDE has been involved from the design stage and is responsible for the operation of the entire channel. The supply of organic waste from :
- Agriculture (agricultural biomass)
- Industries (biological sludge - flotation greases, manufacturing deviations, meat waste, catering greases)
- Communities (lawn mowing, waste from collective canteens, waste from sewage treatment plants)
- Mass distribution (including non-marketable packaged products to be unpacked)
- Operational control of the site and the 1 MW cogeneration engine
- Regulatory management
- Recovery of digestates (centrifugation, evapo-concentration, composting, spreading)
Our offer for the operation of digestion plants
SEDE, a subsidiary of Veolia, has an adaptable and tailor-made offer around digestion.
A commercial and logistical service

Innovations to serve your digestion facility :
SEDE develops fast and reliable measuring tools. This allows us to offer complementary assistance in monitoring biological performance particularly adapted to digesters.
Based on measurement tools based on near infrared spectroscopy technology, SEDE will be able to provide an instantaneous response on the parameters of interest in digestion, associated with the biological performance of a process (dry matter and organic matter content, volatile fatty acid, ammonium and alkalinity concentrations).
