The purpose of this paper is to provide an overview of wood plastic composite plan and estimating the investment of natural wood-polymer or wood-plastic composites based on natural material, wood and polymers. wood-plastic composite decking has made major advances in material performance, processing and user acceptance. WPCs, also referred to as natural fiber polymer composites, are a mixture of wood, thermoplastic resins, and other additives. Wood can be used in various forms, however, it is commonly used in the form of wood flour (fine particles).. Wood plastics composites are a new type of material that are beginning to find applications in a wide variety of fields.In this report at first, Important aspects of application related then economic investment and required infrastructure facilities estimated. This research adapted basics and indicators for construction of WPC manufacturing with economic conditions in Iran. Product in this plan was provided by wood fiber , polymer and agricultural wastes for example rice husk or straw. With regard to the feasibility and strategic rates and the lower priced product compared to the pure polymer, MDF and other similar products in this plan , used technology and utility equipment are available and cheap. An economic plan of WPC production with 5000 tone per year and 60 occupation estimates about 68100 million rials total investment that with rate of return on investment, payback period and break-even point 2.2 year ,46.35 % and 34.21% , respectively. These results suggest that WPC manufacturing Can be economically and good prospects and views for the future are expected.
