In 2009, Emin Leydier was one of the first French producers of recycled paper for corrugated to obtain The FSC® ‘Chain-of-Custody’ (Forest Stewardship Council) accreditation, for both of its paper mills, located at Laveyron and Nogent-sur-Seine. Now, since 1st January 2017, all rolls of corrugated base papers sold by Emin Leydier paper mills are now ‘FSC Recycle 100%’ certified as well.
