For over 10 years, we have been at the heart of the plastics industry’s eco-responsible transition, giving a second life to post-consumer and post-industrial waste. Located in the heart of the Auvergne-Rhône-Alpes region, in Yssingeaux, we collect, recycle, qualify, and reintegrate plastics in ever-greater proportions into the circular economy. We process more than 12,000 tons of plastic a year, with a target of 20,000 tons in the coming years.
