Do you have used gas cylinders containing dangerous gases?
Safe Disposal and Circular Recycling of Industrial Gas Cylinders – Certified Expertise Since 1996
Whether acetylene, oxygen, high-GWP gases, or flammable, corrosive, and toxic specialty gases – we ensure the safe, compliant, and environmentally sound disposal of your end-of-life gas cylinders. Our certified specialists operate under the strictest safety standards, regardless of the contents.
Technical Solutions for Industrial Clients
In addition to our comprehensive treatment services, we offer customized equipment for the safe transport and on-site handling of gas cylinders. Industrial clients can purchase certified solutions that meet the highest safety and efficiency standards – empowering you to manage gas cylinders responsibly and autonomously.
Trusted Partner for the Industry
Since 1996, we have specialized in the disposal of industrial gas cylinders and pressurized hazardous substances. Combining long-standing expertise with cutting-edge technology, we provide reliable, efficient, and fully compliant services trusted by the gas industry, waste management companies, and government authorities.
Closing the Loop – Circular Gas Cylinder Recycling
Every gas cylinder follows a standardized, safety-first process: hazardous contents are removed, cylinders are dismantled and treated, and the reclaimed steel is directed into specialized high-grade recycling streams. This ensures maximum environmental protection and contributes to a sustainable circular economy.
Focus: processing acetylene cylinders
Acetylene gas cylinders contain a porous mass that can hold solvents and, in many cases, asbestos – making them particularly challenging to handle. Our unique, patented disposal process ensures safe and environmentally responsible treatment in full compliance with regulatory standards.
Using a vacuum thermal oven, we heat the cylinders to recover the solvents by distillation. The remaining porous mass is then safely extracted, and the cylinder body is precisely and securely cut. This method guarantees maximum safety and environmental protection, even for the most hazardous cylinders.
Eliminate residual gases to protect the environment
Residues of specialty gases or substances with a high Global Warming Potential (GWP) are never released into the atmosphere. Instead, gas cylinders containing such residues — as well as those with defective valves — are safely processed at our special gases workshop at Trédi Saint-Vulbas, another key Groupe Séché Environnement site.
Using our advanced UTM technology, we ensure the secure, compliant and environmentally responsible treatment of pressurized gas cylinders. This guarantees full adherence to strict environmental regulations while protecting both people and the planet.
