Wood & Wooden Products

Wood & Wooden Products

Global warming and climate change have been a hot issue in the recent past .Carbon accounting in wood products and investigation of the role of forest products in climate change mitigation is now gaining momentum all over the world. EU has already recognized the value of replacing fossil fuel and energy initiative materials with substantially produced wood, including the storage or recycling of carbon in wood products and incentives to promote such uses. Increased use of solid timber, engineered wood and wood based panel displaces energy intensive material such as cement, steel, bricks and plastics in the way that it reduces emissions during production processes. The use of bye- products (wood fuels) for energy generation in production processes has an additional positive impact on the overall carbon balance. Therefore, the substitution of high energy products offers a strong potential to decrease the use of fossil fuels and increased carbon storage, thus enhancing the carbon sink effect. Material / Product certification is an important aspect of any manufacturing process, particularly those having highly heterogeneous materials like wood , for maintenance of quality of wood ,SRI plays an important role in helping industry in this with a scientific approach .
