Presentation

Recycled steel reinforcement at Michelin

Michelin is reducing its ambition to use renewable and recycled materials, reduce CO2 emissions and recycle its product to all the raw materials used in tires. For its steel cord and bead wire, Michelin is converting its raw material supply to steel made on an electric arc furnace with a high percentage of scrap feedstock. To overcome the technical and supply challenges related to this feedstock and increase the recycling of end-of-life tires, Michelin is developing a closed-loop approach for the steel for tire reinforcement. Michelin will present some promising results and perspectives about this approach.
