post−industrial waste wood
post−consumer waste wood - Opis:
- Timber harvesting and wood processing are inseparably accompanied by various waste production. Waste wood, in the form of remains of tree care and correctly conducted logging operations, may be a product of forestry activities. It includes branches, boughs or rootwood. Post−industrial waste wood varies in form and the degree of shredding, and in terms of its contamination with both chemical compounds and mechanical or mineral pollutants. Daily living activities are a source of post−consumer waste wood, including demolition wood and furniture, the management of which is the most challenging task. Agricultural crop waste is a category that is often overlooked. It includes pruning waste, waste being an effect of plant regeneration in orchards and soft fruit plantations, or field or roadside shrub removal. The difficulty with assessing potential quantity of waste wood is to large extent caused by the lack of rational and comprehensive legal solutions. It should be noted that waste holders generating up to 10 t of sawdust, wood particles, wood, waste particleboards or veneer, or up to 10 t of waste bark or cork annually, are not obliged to keep a record of such waste. Another important factor hindering the determination of the supply of waste wood in Poland is the lack of a clear system of its classification. Consequently, there is no data concerning waste wood quantity. Considering the supply of wood materials and products, their characteristics and intended use, we can assumed that the greatest quantity contaminated waste is generated by furniture and wood−based panels industry. The paper also points out the inconsistencies in the literature regarding the determination of the potential waste wood base. In general, approximately 8.0 million m3 of post−industrial waste wood are generated in Poland every year. The supply of post−consumer waste wood is at a level of approximately 5.3 million m3. The supply of wastes from forestry and agricultural crop waste equals 3.8 million m3 and 0.4 million m3, respectively. So approximately 18.0 million m3 of waste wood, varying in terms of origin, form and properties, may be generated in Poland annually. Considering the wood shortage that can be observed in Poland, as well as the substantial quantities and availability of waste wood, these two latter factors may constitute an alternative source of wood raw materials for a number of sectors of the economy.
