SEDE deploys professional services to accompany you in the follow-up and treatment of your waste.
Faced with new regulations and environmental issues, waste management has become a major challenge for many communities.
SEDE has developed a liquid digestion process for waste from agriculture, the food industry, supermarkets and communities.
Discover our industrial site for the digestion of organic waste at Graincourt-les-Havrincourt (62).
SEDE also has an agricultural digestion site in Soudan (44) :
Waste recovery by digestion
SEDE provides a guarantee of a tailor-made and adapted logistics, from organic waste removal to treatment by digestion, specific to your community, with many advantages :
- Optimisation of the entire process and logistics for your community.
- A complete solution, also including water treatment solutions.
- A unique market position offering access to highly competitive financial solutions.
- A guarantee of waste removal under contract.
Optimise the treatment of organic waste
Have a complete set of services at your disposal: diagnosis, identification of your waste, provision of containers for storage, customer extranet, traceability monitoring, commitment to removal and treatment, etc.
Moreover, SEDE offers logistic solutions for all types of waste and organises pumping collections. Storage tanks are used to optimise collection operations.
Analyse and characterise your organic waste
Several "liquid" digestion pilots are being used to validate the technical and economic feasibility of a process. The purpose of this equipment is to :
- Test the methanogenic potential of a waste.
- Charactise the quality of the biogas produced (CH4 and H2S).
- Study the quality of the digestate (agronomic value).
- Define the physicochemical characterisation of the waste
Deconditioning your packaged waste
Some packaged waste, previously sent to landfill or incineration, can now be digested.
A deconditioning stage is thus necessary to separate the packaging from the organic fraction which will be recovered as energy by digestion. The packaging is then recovered via other suitable channels.
Digestion of organic waste
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 are broken down into biogas (methane), water and CO2.
Recover any type of waste or organic residues
Digestion is a treatment method for many types of waste and residues :
- 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.
When lost material becomes raw material
This technology for the digestion of organic waste has many advantages :
- Production of renewable energy through biogas production (mainly methane).
- Production of a stable residue that can be used as fertiliser.
- Significantly reduced olfactory inconveniences.
- Reduced soil load.
- Very good carbon footprint (CO2 production).
- Your organic waste benefits from dual energy and agronomic recovery: production of electricity, heat and production of a stable residue that can be recovered in the form of fertiliser.
