Ramping up the expansion of the circular economy

From waste to low-carbon resources

As natural resources become increasingly scarce, we have a responsibility to rapidly expand the circular economy.

Our business model, which has long been ahead of the curve, became even more meaningful with the adoption of the “Anti-waste and circular economy” law in France in 2020.

Moving from a conventional linear model – extraction, production, consumption, disposal – to a circular model helps relieve pressure on resources and ecosystems, and respond to the climate emergency.

Leveraging our R&D capabilities to achieve industrial ecology

We focus our R&D efforts on developing a wide range of solutions to preserve resources and reduce the volume of non-recoverable waste. As such, we developed 32 new products/processes in 2023.

Our leitmotif: transform as much waste as possible into all kinds of new, locally produced resources, creating either reusable material or energy and thereby encouraging relocalization and decarbonization.
Our strategy: focus all our efforts into innovative procedures and invest in cutting-edge technology. Our innovation strategy, which spans all areas of the circular and energy recovery from waste, was recognized with the Greentech & Energies award in 2021.

Multi-faceted performance

Alongside our client partners, we protect the planet’s resources. By harnessing the circular economy, together, we generate multi-faceted performance, which combines financial success with performance that benefits the environment, public health and the community in all the areas in which we operate.

Recovering recyclable materials

Regenerating chemicals

We regenerate exhausted solvents
We apply innovative purification and distillation processes to produce recycled solvents that display the same characteristics as virgin solvents from fossil fuels. This enables us to preserve geostrategic resources, avoid destroying industrial waste and supply a locally produced product to the many industries that require these chemicals.

We regenerate bromine
Bromine is used in a variety of sectors, including the pharmaceutical, cosmetics, and chemical industries. Our innovative technology enables us to extract nearly 99% of the bromine present in certain hazardous waste that first needs to be eliminated. Our regenerated bromine substitutes the need to extract bromine from the Dead Sea, which can be complex, costly and dangerous for the environment. Our alternative helps to relocalize the industry and cut our dependency on a distant geostrategic resource.

Rehabilitation: treating and reusing polluted land

Séché Environnement has developed specialist expertise in rehabilitating sites and treating polluted land. We can treat and rehabilitate land polluted by years of damaging activities, such as former industrial plants or landfill sites. After being treated in situ or at our specialist platforms, the affected soil can be reused as backfill by the construction industry. The circular economy can also enable towns and regions to reclaim their land assets and combat urban sprawl.

Reusing and recycling gas canisters

At our Trédi facility in Saint-Vulbas (eastern France), whose expertise in managing highly complex hazardous waste is renowned around the world, we developed a unique workshop to treat special gas and greenhouse gas. In this workshop, gas canisters are emptied, washed and then sent out to be reused if they are in good condition, or recycled if they are defective.

Household waste: we sort your recycling

In our sorting centers, waste from various recycling collections (paper, card, metal, plastic and wood) are separated by type, packed and then directed to the industrial channels able to reuse them.

Bottom ash: recovering the waste from waste

Bottom ash is the solid residue produced by incinerating waste. When everything that can be burned has been burned, bottom ash is what remains. We remove the metals that can be recycled, and after several treatment processes, the remaining bottom ash is reused in the base course layer of new roads.

Waste-to-Energy

Waste still contains energy. For many years now, Séché Environnement has been developing facilities and processes to recover and provide low-carbon alternatives to fossil fuels. This is essential to preserve natural resources and thereby reduce the carbon footprint of manufacturing, farming, services and housing.

Solid Recovered Fuels (SRF)

SRFs are hailed as a new energy solution. We produce SRFs from non-recoverable waste that up until recently was considered as unusable in any way and could only be stored. As pioneers in this area, we built France’s first thermal power station in 2017 at our Changé facility (northwest France).

Waste heat

This is the energy we recover from waste incineration. A truly local energy source, waste heat can be harnessed and directed into urban heating network or industrial heating networks, like in Salaise-sur Sanne, near Lyon.

Biogas

It is produced naturally as organic waste decomposes. It can be injected directly into gas networks or used to generate electricity, heat or biomethane.

The industrial heating network in Salaise-sur Sanne

At our Trédi de Salaise-sur-Sanne industrial facility (southwest France), we use elevated temperatures to treat the hazardous waste produced by nearby plants and in return supply them with the heat produced.
