I have just returned from the factory floor, and was fasinated by the process by which recovered plastics that otherwise would rest in (the frighteningly close to capacity) landfill sites of Britain, are turned into our recycled plastic decking & walkways.
It seems to me the only logical method of producing such a product, saving trees while removing waste from our environment
Anyway, heres the process in pictorial form
Shredded plastic coming in
The moulds
A finished piece being removed
Cutting to size with a circular saw
The result: Beautiful!
