The digester of SAS Meetha in Soudan (France), takes a new step in its development by moving to biogas injection.
SEDE has undertaken a vast programme of work on the SAS Méétha site, an agricultural digester in Soudan, bought from a farmer in early 2018.
This work has followed 3 objectives :
Securing digestion and composting activities by completely sealing the site and enlarging the water and digestate collection basins.
Abandoning electricity production (cogeneration) to switch to injecting biogas into the network thanks to a partnership with the companies Air Liquide for the purifier and GRDF, the network manager, to develop the activity within the framework of administrative authorisations, with an average production of 170 Nm3/h, by favouring more methanogenic inputs.
Reinforce cooperation with the agricultural world and the AFIs (valorisation of by-products from agro-food activities).
On 27 September 2019, Paul Antoine SEBBE, President of SEDE, came to present these achievements by thanking all those who actively participated.
The event also coincides with the 40th anniversary of the creation of SEDE, an opportunity to present the progress made in the field of organic product promotion through the companies that today make up Veolia's agronomy centre.

At nominal capacity, the site will be able to treat :
20,000 t/year of input materials (60% agricultural inputs and 40% by-products from local AFIs)
3,000 t of dry digestate and 16,000 m3 of liquid digestate,
valorised on a 2,000 ha spreading plan
14,600 megawatt PCS of biogas,
equivalent to the gas supply for 4,500 people
