Composite wood is a mix of wood and plastics usually with wood making up around sixty-percent, and plastics making up the rest. One of the wonderful things about human engineering is that when we want to make something better, in this case, it’s the idea to make something that is more durable than traditional lumber, something that is hardier towards issues of damp, mold, cracks-cuts-and scrapes, sun-bleaching, and sickly children. All the sorts of things that concern real people with real problems, and accidentally they do something which is good for the environment.
