France: Placo and Serfim Recyclage have revealed that they started operating a new 140t/day plaster recycling plant at Quincy-Voisins near Paris in October 2021. The companies say that the Pari Plâtre site is the first in the Paris region to be solely used for recycling plaster waste from construction sites.
Daily deliveries via the Placo Recycling network bring plaster waste from within a 250km radius to the site. The waste is then sorted by hand along an 80m production line to remove wood, ceramic, cardboard and polystyrene fractions. These materials are recycled separately. The plaster is crushed and screened with a 98% recovery rate. The plant stores reclaimed gypsum in two 80m3 silos. The gypsum is then transported to Placo’s gypsum wallboard plant at Vaujours for use as a secondary raw material.
Placo says it is the leading recycler of gypsum in France. Following the opening of Pari Plâtre the company has increased its plaster recycling target in 2030 target to 200,000t/yr. This will allow the subsidiary of Saint-Gobain to use up to 30% of recycled materials in the production of its wallboard products.
