In the Grand Est region, the value of the forest-based sector is dominant, with a turnover of EUR 11 billion achieved by nearly 10,000 companies with 55,500 jobs. It is also a contrasting industrial sector where there is a strong synergy between tradition and innovation. The energy transition is inevitably accompanied by new uses of wood. In order not to create tension on existing markets, these new uses of the material require innovation. This applies to the whole sector, from forest management to optimisation of the use of wood. While timber construction recently accounted for less than 10 % of new constructions in France, this figure now stands at 25 % in BBC houses, reaching 43 % of passive buildings in Europe. These figures therefore show that the construction sector will still provide economic development. But other areas such as the chemical valorisation of wood are also booming. In order to be able to train the doctors and engineers of tomorrow able to integrate these new dimensions, to be able to develop new innovations through the research carried out in our laboratories, investments related to construction, the thermal of the habitat, robotics, factory 4.0 and the chemical valorisation of wood must be made.
