Deck makers made Composite decking from materials that are eco-friendly and free from toxins. Composite decking makers use sawdust or wood fibres and recycled plastic material in making the decking. The recycled plastic material that goes into composite decking can include polypropylene or polyethylene. 

Manufacturers use polyethylene in the packaging industry for plastic milk bottles, shampoo and conditioner containers. At the same time, industries also used polypropylene extensively in packaging edibles. It is also used to make plastic parts in the automobile industry because of its ability to resist chemicals.

Both the polypropylene and polyethylene plastics work well when combined with wood fibres to create a strong and composite decking material. The deck makers combined the wood fibre with the plastic material and bonding agent in co-extrusion process. All the raw materials are combined by the makers and then introduced into an extruder that melts the mixture. The mixture undergoes a heating process in the factory, heated and poured into a moulding material. 

The manufacturers moulded the wood fibre and recycled plastic material mixture into shapes and allowed it to cool. In some cases, composite deck makers placed capped composite polypropylene shells around the three sides of the deck. This process protects the composite decking against stains, everyday foot traffic, and spills.
