Méthanisation des sous-produits et déchets alimentaires

By-product digestion

Opt for a range of professional services and support in the monitoring and treatment of your waste and organic by-products.

 

Regulations require industrialists, large producers of organic waste, to sort and recover this latter. The digestion channel is a relevant response to the dual problem of treating fermentable waste and producing green energy.

SEDE has developed a liquid digestion process for waste from agriculture, the food industry, supermarkets and communities.

Finally, digestion treatment through multi-site management is secured through partnerships.

 

 

Valorise your by-products by digestion

With the personalised help of SEDE, you will be able to optimise your logistics, from the collection to the treatment of the by-products by digestion, with many advantages :

  • A global solution, which includes water treatment solutions,
  • A unique market position offering access to highly competitive financial solutions,
  • A guarantee of waste removal under contract.

 

Optimisation of by-product processing

Opt for a complete range of services: diagnosis, identification of by-products, provision of containers for storage, customer extranet, traceability monitoring, commitment to removal and processing...

SEDE can also take care of the transport of any type of waste.

 

Determine the methanogenic potential of a waste product

Several "liquid" digestion pilot plants are being used to validate the technical and economic feasibility of the digestion process. The purpose of this equipment is to :

  • Determine the methanogenic potential of a waste product,
  • Characterise the quality of the biogas obtained (CH4 and H2S),
  • Study the digestate product to determine its agronomic value,
  • Define the physicochemical characterisation of the by-products.

 

A controlled digestion process

Digestion is a biological process of decomposition of organic matter by bacteria in the absence of oxygen (anaerobic fermentation process).

By optimising temperature and humidity, organic materials can be broken down into biogas (methane), water and CO2.
 

Valorise any type of waste or organic residue

Digestion is a technology that can be used to valorise many types of materials, residues and rejects:

  • Sludge from the food industry,
  • Sludge from sewage treatment plants and water treatment systems,
  • Solid fatty waste,
  • Residues from food production,
  • Waste from the agricultural industry.

 

An example of circular economy :

The organic waste is recycled into green electricity and fertiliser. Thanks to digestion, organic waste allows :

  • The production of renewable energy through biogas production: electricity and heat,
  • The production of a stable residue that can be used as fertiliser,
  • A very good carbon footprint.
