After 10 years of Research and Development, the first “Chartherm” industrial unit is now operating since nearly half a year, thanks to Thermya SA, engineering company, current owner of all the “Chartherm” process Patents and Rights. In accord with the recycling contracts signed with several French major companies, the “Chartherm” plant, located near Bordeaux, recycles every day several hundred CCA treated wooden poles, mixed with some creosote, CCB and CFK treated ones, since the “Chartherm” process do not requires any pre-sorting, being able to process all kinds of treated wood, whichever be the type of contamination of the wood. The "Chartherm" process consists in a “distillation” of wood, at low temperature, in a neutral atmosphere. Each metric ton of wood waste getting into the system produces an average of 300 kg of clean Carbon powder, which has many applications in different industries. All these makes the “Chartherm” process be a very attractive treated wood recycling solution from an environmental, technical and economical point of view.
