Given the present-day challenges of global warming and the scarcity of resources, Séché Environnement is committed to promoting energy production from wasteAccording to French Act No. 75-633 of July 15, 1975, any residue from the production, transformation process or use of any substance, material, product or more ... resources at all its treatmentPhysical, thermal, chemical or biological processes, including sorting, which modify the characteristics of waste so as to reduce its volume and dangerous ... facilities.
The recoveryProcess that restores the physical-chemical characteristics to waste enabling it to be used as an alternative to virgin raw material. of biogasGas produced by anaerobic breakdown of the organic matter contained in certain waste. from the natural degradation of biomass contained in wasteAccording to French Act No. 75-633 of July 15, 1975, any residue from the production, transformation process or use of any substance, material, product or more ... at storage facilities : all sites have been provided with recoveryProcess that restores the physical-chemical characteristics to waste enabling it to be used as an alternative to virgin raw material. tools (turbines or generators) to produce electricity that is fed back into the grid.
Furthermore, the Changé site has developed a unique type of cogeneration and supplies a portion of its thermal energy to an agricultural cooperative located in the immediate vicinity of the site as part of an industrial ecology strategy.
Production of thermal energy (steam) at thermal treatmentTreatment of waste through the use of heat. This includes incineration, pyrolysis and thermolysis. facilities (see also) for industrial users in the immediate vicinity. A portion of such energy can also be recovered in the form of electricity or, depending on prevailing local conditions, to meet in-house needs.
Production of SRFs (Solid Recovered Fuels) from the mixed, non-recoverable, ordinary fraction (bits of plastic, wood or paper) to supply compliant boilers with fuel in order to guarantee the traceability of the wasteAccording to French Act No. 75-633 of July 15, 1975, any residue from the production, transformation process or use of any substance, material, product or more ... and its handing under the best sanitary and environmental conditions.
Development of methane production tools in order to deliver a specific solution using separately collected fermentable wasteAccording to French Act No. 75-633 of July 15, 1975, any residue from the production, transformation process or use of any substance, material, product or more ... for generating electricity.
Because of the total energy output of all the Group's sites, Séché Environnement is able to generate more than 250,000 MWh perPurified emission residue: Residue resulting from dust removal and the neutralization of incinerator emissions. May sometimes be confused with fly ash. year, of which nearly 70% is labeled "green electricity" (fraction derived from biomass).
Séché Environnement is 120% self-sufficient in meeting all its energy needs.
At the SVO site, biogasGas produced by anaerobic breakdown of the organic matter contained in certain waste. is recovered by generators to produce electricity. Combustion from the engine releases heat, which is used on-site to feed pools of microalgae grown for the manufacture of diesters.
This offers a triple advantage :
A unique form of cogeneration (combined heat and power): ultimately the algal cultures should absorb all the heat that is produced and the project will transition from the pilot study phase to the industrialization phase.
The use of heat in cultivating microalgae promotes their growth and development.
RecyclingProcess that aims to introduce materials from waste into a production cycle in order to fully or partially replace virgin raw material. CO2 and combating global warming: injected into the pools where algae are being cultivated, the CO2 generated during electricity production operations promotes the growth of the microalgae, which will absorb nearly all of it during development.
Manufacturing biofuel. Microalgae have very high lipid content (40%) and produce a yield 30 times greater than that derived from other plants, such as colza. Moreover, their use in manufacturing diesters does not compete with other plants crops that are likely to be used as food for animals or humans. This is a decisively sustainable development-oriented approach.
