Comprehensive hazard management

Séché Environnement is one of France's foremost providers of hazardous waste recovery and treatment services.

We process, recover and treat the most complex waste, while guaranteeing the highest standards in terms of protecting human health and the environment. Our laboratories identify the type of waste and track environmental indicators (such as gas and liquid discharge and soil and water table monitoring)

Our tailored solutions, designed to recover the energy and material contained in waste, enable you to reduce your environmental footprint.

Collecting, sorting and bundling hazardous waste

Depending on the nature and volume of your waste, we provide appropriate solutions to condition and transport the material.

If your hazardous waste is contained in small tubes, pots, bottles or containers, such as paint pots, glue, solvents, oils, pesticides, batteries, extinctors, asbestos, gas cylinders, varnish, or chemicals, our sorting and bundling platforms are able to recondition them and send them on to the appropriate treatment channels.

We develop circular economy solutions to send all recyclable materials to the appropriate recycling channels, including plastics, flexible hoses and service stations, metals, gas cylinders, transformers, and bromine waste.

Recovering energy from hazardous waste

The thermal treatment channel incinerates waste in furnaces to produce low-carbon energy that offers a suitable alternative to replace fossil fuels.

Non-recyclable waste must be sent to long-term storage and confined using a double liner system. 3D geolocation data is recorded to ensure traceability for years to come.

Our solutions to handle special waste

Asbestos

We process asbestos waste produced by dismantling industrial facilities, or removing the substance from urban or natural sites before sending it on to its final desination.

Industrial gas

In our unique workshop designed to closely manage risks, we process gas cylinders containing special inflammable, corrosive or toxic gases and potent greenhouse gases. Following a circular economy approach, we recover certain gases and residues, as well as the cylinders, which if damaged are conditioned and loaded in specially designed cages so they may be transported safely.

Polluted soil

Contaminated with heavy metals, such as mercury, lead and zinc, hydrocarbons or asbestos, we sort and treat polluted soils so they may be reused.

Solvents

As experts in distilling chemicals, we process exhausted solvents to regenerate them and give them a second lease of life.

PCBs and transformers

Our Tredi Saint Vulbas facility is the only site in the world able to both decontaminate electric transformers and eliminate fluids polluted with PCBs (polychlorinated biphenyls). Our processes make it possible to reuse or recycle the metal components (steel, copper, etc.).

Bromine

We are the world's foremost producer of recycled bromine. Our process makes it possible to recover nearly 99% of the bromine present in industrial process waters. Regenerating bromine waste generates 20 times less CO2 emissions than producing virgin bromine.

Pyrotechnic waste

A number of industries are concerned by the need to treat pyrotechnic waste, such as ammunitions, detonators and shells, air bag cylinders, rockets, and fireworks. Our specialist teams bundle, condition, transport and process this highly hazardous waste. They also take part in earthworks operations to detect and disarm ammunition on former battlefields or military land.

Mineral waste

Our physico-chemical treatment units are equipped to process your hazardous liquid mineral waste (acids and alkalines) that has been contaminated by heavy metals, cyanide or sulphur. 

How we process hazardous waste

Preliminary identification and acceptance of waste through a simplified, digitized procedure

You provide us with a sample of the waste to be processed, which we analyze to determine the appropriate treatment channel. Our chemists can also carry out their work directly on your premises, in order to support you in the analysis and conditioning of your waste.

Our account manager draws up a proposal and supports you throughout the project.

All the documents, including the preliminary identification form, the pre-acceptance certificate, and the waste tracking form are completed digitally and available in your Séché Connect account to simplify the administrative process.

Optimized logistics for collecting and transporting waste

We can collect and transport your non-hazardous waste from where it is produced to our treatment units, taking an eco-logistics approach that optimizes transport time and resources to cut the carbon footprint of transit.

We guarantee the traceability of your hazardous waste through the online Trackdéchets platform developed by the French Ministry of Ecological Transition.

Waste treatment and recovery to extract recyclable materials and produce energy

After having checked the compliance of the load when it arrives at our treatment facility, your waste is sent to the previously identified channel to control hazards as well as optimize recovery of recyclable materials and energy.
