Wood

Wood is used in many areas (almost all) from construction to paper creation. We list first the techniques to harvest and prepare the wood, then techniques to use the wood. Wood is used in many fields, from the creation of paper (cellulose) to construction. Some “exotic” woods are used in certain areas according to traditions. These woods have very exotic names (like Massaranduba, Padouk)! The protection of forests and their equitable management is a focus for all. Forestry (cultivation of the forest (Silva, in Latin, forest)) has made enormous progress and discovered enormously in recent years. First of all, it is important to take into account these studies: diversity of species in a defined space, connection between trees, need for trees, forest management, etc. We will involve researchers working in this field. Everyone can do something (in their garden, their estate, their municipality, etc.). Like any agricultural and industrial sector, the forest-based sector is responsible for air emissions at every stage of the life cycle of forest products.

The solar energy used for the photosynthesis of woody biomass can be recovered by combustion at different stages. Emissions from wood combustion are those from the combustion of any hydrocarbon product, i.e. mainly CO2 and depending on the combustion quality, more or less CO, NOx and VOCs, as well as trace amounts of VOCs, PCDDs/PCDFs and PAHs. Wood and wood-based products contain very little sulphur, resulting in very low SOx emissions and trace amounts of metallic elements, which can be found in air emissions. Wood also generates dust emissions, the quantity of which depends on the combustion quality and the performance of the filtration systems.
