The wood industry is a circular economy model based on a biosourced and fully biodegradable material.
However, the various constraints imposed by its use in furnishings and construction can complicate its
recycling and pose problems for recovering the material at the end of its life. In the context of the ecological
transition and the objectives of decarbonizing buildings, the use of wood and derived materials is increasing
sharply. Climate upheavals are changing the supply of resources. Increased demand from the wood energy
sector is also putting pressure on resources. In France, the deployment of the AGEC law, the extension of
Extended Producer Responsibility to the building sector and the ambition to decarbonize industry and
buildings by 2030 make recycling an industrial priority. Currently, a large proportion (60%) of end-of-life wood
from the construction and furniture industries is not recycled, due to its content of substances of concern
under REACH regulations, environmental concerns and industry standards (EPF thresholds). Recycling of this
type of material concerns almost exclusively particleboard, with numerous disparities and unresolved issues
such as the loss of quality of the wood material and the recycling of fiberboard (MDF, HDF)[1]. On the other
hand, the qualification and reprocessing of demolition wood prior to re-use is a new technological and
economic challenge. At the laboratory, we are developing an integrated approach aimed at overcoming the
scientific hurdles posed by the industrial problem of wood recycling [2]. The material recovery of end-of-life
wood will be presented here through two examples that can be deployed on a territorial scale in the industrial
fabric without disrupting the existing value chain. The examples presented here show a versatile way to
recycle MDF fiber including UF resin removal [3] and integration in new materials.
