Softwood and hardwood decking are by definition made from wood. Wood-Plastic Composites (WPC) use a blend of wood fibres and plastic; made using high energy processes.
Not a single tree is cut down to produce Millboard as it is a mineral based Polymer Resin Composite (PRC). It is manufactured in the UK and classed as a low energy process, meaning the demand on our natural resources is minimal.
