The society needs to reduce the human environmental footprint by making materials last longer and choose materials with minimum release of CO2. At present, the building industry is responsible for about 40% of the global CO2 release. As the industry is facing the shift in society requring more sustainable and «green» solutions, alternative building materials are explored.
An excellent alternative to concrete and steel is wood, which has become increasingly popular as construction material for urban architecture. Wood is a renewable resource with positive environmental impact as it can bind CO2. However, wood faces some technical weaknesses as compared to other building materials. Poor color stability and susceptibility of growth of microorganisms like fungi and mould spoil the nice natural look and durability of wood, making it less attractive.
