Most of the composites available on the market today are produced with a high durability to ensure product longevity. Unfortunately, in order to make these products, companies have traditionally used non-biodegradable polymers and fibers, which were usually made from non-renewable resources. With an increasing number of composite applications, how these composites are disposed of after their intended life is becoming critical. A typical composite, which is made up of two dissimilar materials, is not easily recycled or reused.[3] This inability to recycle has lead to the incineration or disposal of these composites, which has been very expensive and has increased pollution. Wood plastic composite material

Greenpeace groups and NGOs have long been researching and pushing the use of "green-composites" to improve the performance, weight and cost of composite products. One of these "green" composites is wood-plastic composite. In WPCs, biodegradable fibers are used as a replacement for inorganic fibers, such as aramids and glass. The use of wood fibers instead of inorganic fibers make WPCs more energy efficient as it allows for left-over wood products (like wood flour, wood scraps, old furniture, hemp fibre, bamboo...) to be reused in their production, which cuts down on the expense of their disposal. While traditional composites typically have to be burned or left at the landfill after being used, WPCs can be either neutrally CO2 burned or reused as acoustic or thermal insulators (due to there hollow cellular nature).

WPC is a break-through for plastic recycling in Australia. This co-mingled wood plastic composite (WPC) is made from 100% recycled plastic and recycled wood and is stronger than normal recycled plastic therefore allowing specifiers the choice of utilising recycled material in areas not possible before.

WPC looks the same as normal recycled plastic except smoother and more consistent in its appearance. The secret combination has already been responsible for diverting significant quantities of waste from landfill.

Wood plastic composite is a new class of composite materials in recent years. It is made of by using of polyethylene, polypropylene and polyvinyl chloride, etc. to replace the usual resin adhesive, mixed with 35% -70% of wood power, rice husk, straw and other wasted wood fibers to make this new material. Then by extrusion, molding, injection molding and other plastics processing, wood plastic composite is produced out with different profiles.

Wood plastic composite can be used for landscaping, interior and exterior decoration, flooring, guardrail, flower pot, pavilions. Wood plastic composite does not require secondary processing (such as veneer, transfer, paint, etc.), and has a natural wood texture. Decking: including platforms, road boards and site pad.

In addition to decking, there are wall panels, ceiling, decorative panels, running boards, siding, highway noise barrier, beach shop flooring, building templates, building templates, moisture-proof board. In addition, wood plastic composite is also for decorative borders, fences and garden handrails, combination plate and tray packaging, and furniture (including outdoor open-air tables and chairs), the ship cockpit partitions, office partitions, storage boxes, flower boxes, activity racks, blinds, etc.

Plastic- WPC adopts the plastic material containing both new and reclaimed HDPE (high-density polyethylene )as per the strict ratio. Other plastic material (like PP-Polypropylene ,PVC-Polyvinyl chloride etc) can replace PE if our clients have special demands. Wood–plastic composite decking lumber

Chemical additives (Couplant)- Like colorants, coupling agents, stabilizers, blowing agents, reinforcing agents, foaming agents and lubricants make wood and plastic compounded perfectly with patent technology.

The production of Wood-Plastic Composites typically uses a fine wood waste (cellulose based fiber fillers such as hardwood, softwood, plywood, peanut hulls, bamboo, straw, etc.) mixed with various plastics (PP, PE, PVC). The powder is extruded to a doughlike consistency and then extruded to the desired shape.

Additives such as colorants, coupling agents, stabilizers, blowing agents, reinforcing agents, foaming agents, and lubricants help tailor the plastic end product to the target area of application.

With up to 70 percent cellulose content, wood-plastic composites behave like wood using conventional woodworking tools. At the same time, they are extremely moisture-resistant. There is little or no water present, thus increasing resistance to rot.

Wood-plastic composites are already widespread in outdoor use for decking, cladding, park benches, etc. There is also a growing market for potential indoor uses such as door frames, trim and furniture.

Presence of just 4-5 players pan-India shows the huge scope this industry has, according to both Naveen and SN Chakravarty. Some manufacture the raw material while others import from China and other countries and sell in India. Delta currently imports from Australia and Korea on order from a company called Komposite Woodit. It customizes the product according to customers' requirement. In India, there is no direct link between the manufacturers and the distributors, as their markets and procurement sources respectively, are different.

In the case of Delta, they had studied the 20-year climate of several Indian cities with a market research extending to two years. Local climate is very important for customizing the WPC products. However, it would still be not wise to step into this industry without advice of consultants as it requires very specialized knowledge. "Its difficult to compete with Chinese companies as they have acquired big scale," says Rahul Jindal, Deckcrafts, which manufactures outdoor decking of WPC. Wood plastic composite board
