Wood-plastic composite materials is the ideal industry of circular economy

Wood-plastic composites have the advantage that the performance of these two different materials can be ideally combined together. Plastic extrudates filled with wood powder (sawdust) or wood fibers have so far been mainly used in the construction sector, such as for balcony covers and for windows, doors and railings. The most important market in the United States, in 2000, produced about 200,000 tons of wood-plastic composites. The global annual growth rate is 25%. The main advantage of these composites is their wide design range, the production of waste-free and approximately wood-like appearance. Up to now, the use of wood fiber / plastic composites in injection molding has not been common, although they have a number of advantages. In many cases, the cost to the processor of using wood fiber / plastic composites is considerable. At the same time, the final product behaves as well as non-filled plastics, and in some cases even better. The mechanical and optical requirements on the part will naturally play an important role in the chosen material. Regardless of their environment, the potential savings from lower material costs and more economical processing of composite pellets. Despite the long grinding process, the price of wood fiber is much lower than the primary plastic. The low density of wood fibers also contributes to a reduction in cost compared to other reinforcing agents. Therefore, the wood fiber / plastic composite has a very good volume price. Finally, wood fiber / plastic composites can bring ecological benefits: they are mainly composed of recyclable raw materials, and can be recycled. In the field of furniture and construction applications there is another big advantage: wood fiber / plastic composite plastic parts can be processed and assembled like a wood, using the saw, drill, cut the same tools. Because the thermal expansion of the composite is consistent with that of the wood, there is no problem in use, and the possibility of deformation is lower than that of the non-reinforced plastic, and the stability is higher.
