Green project to convert agricultural bye products into high value finished products-WPG

摘要

WOOD PLASTIC COMPOSITE(WPC)is a combination of wood and plastic extruded together or moulded together in different forms.Wood-plastic composites,as indicated byname are composite materials made of wood fiber/wood flour/Agricultural bye products like rice husk,Straw,Bagasse etc.and thermoplastic(s)like PE,PP,PVC,PL A etc.WPC is relatively new materials specially for Indian markets,however it is widely used in other parts of world. Wood polymer composites(WPCs)can trace its roots considerably earlier,with Gruppo Ovattifici Riunitti(GOR)producing’Woodstock’for Fiat cars in 1972,and Sonneson AB producing PVC-wood fibre floor tiles in Sweden in 1973.Various research activities span the decades which passed before the sector gained momentum in the 1990s,for example,seeing fourfold growth between 1997 and 2000.The new impetus was provided by the twin aims of exchanging petrochemical materials for increased bioderived sustainable materials;and the need to reduce waste to landfill and explore recycling technologies.WPCs were seen as a product into which wastepaper and/or post-consumer plastics could be recycled.
