The research project "CoolWood" aims to develop an innovative conservation of wood material for optimum support of its quality during storage and thus enabling new modes of organization in the forest / wood industry. The quality of raw and processed wood is constantly challenged by attacks of biological origin. In the absence of conservation measures, the woods become unsuitable for most technological uses after a period depending on the species and weather conditions, they can lose up to their full market value. Maintaining the quality of wood during storage is therefore a key issue, as part of "normal" functioning of the forest / wood industries but also in situations of emergency following storms or forest epidemics. Although the last major storms in France in 1999 and 2010 respectively have landed 140 million and 40 million m3 of windthrow (trees blown over). The general principle of protection of the woods is the realization of conditions minimizing the development of wood-destroying organisms by chemical treatment or by acting on the wood moisture content, oxygen content of the atmosphere or ambient temperature. The effect of temperature on the preservation of wood, although it is recognized, has never been seriously explored systematically on a scientific viewpoint. Its technological implementation has never been studied. In response to this gap and in order to achieve the definition of an operational prototype, the objective of the research project "CoolWood" is, through a program lasting 43 months, to validate the feasibility Scientific method of preservation of logs by controlling the temperature and humidity and then design an industrial process optimized technically, economically and environmentally, to evaluate its performance and its preparation for future implementation through to an industrial prototype. This work is underpinned by a patent that one of the project partners filed on an innovative wood preservative during storage by temperature control. Our process meets the needs of structuring the forest / wood industry, industrial needs by improving product quality and also to societal needs in crisis situations. It can replace existing processes that remain generally unreliable for certain pollutants or heavy users of water resources. The sustainable development aspect is thus a strong component in the project. Finally the economic aspect is also very present in the benefits of this process, particularly through industrial competitiveness gains expected and the contribution that the process can make to the objective of increasing logging initiated by French government (increased wood mobilization Forest + 60% of the volume between 2009 and 2020).
