Feasibility study for a dedicated pressure treated wood waste management system
C Cornillier, I Buda, E Heisel, G Labat
For the creosote treated wood coming out of service, it has been estimated an amount of 200 000 t per year for the next twenty years, and 100 000 t per year afterwards. With a limited number of actors, mainly SNCF (as producer and as user), no importations, and available energy recovery options, it appears possible for setting a dedicated wood waste management system, if the SNCF agrees to.
For the CCA treated wood, the amount of it coming out of service will increase and will be much more important, reaching about 400 000 t per year. For setting a voluntary dedicated waste management system might be much more difficult, because the importation is very important (about 50%), the margin of product low and the actors and users are numerous.
Over the answer of the question on the feasibility for setting a dedicated pressure treated wood waste management system, this study must allow also define the priority actions to improve the pressure treated wood waste management.
