If this product can replace roofing boards (usually plywood), would that mean no more need for shingles either? A close join with good caulking seems to me a reasonable roofing material. Other similar uses seem to exist in places where plywood is traditionally used but rots away relatively quikly. Could this also be used in lieu of pressboard for cheap furnishings?<p>My big question tho is how much energy does this process use? Is it energy efficient enough to offset the wood/glue/manufacturing of plywood stuff?
This article didn't make a lot of sense to me.<p>Plywood can't be recycled because it has nails and paint, but plastic can?<p>The reason that folks don't recycle plywood is that it's part of construction debris. When you gut a place, you end up with dumpsters full of random crap: sheetrock, plywood, studs, pipes, etc. The labor to pick this apart isn't available at a reasonable price.<p>I don't see that replacing plywood with plastic changes the economics here.<p>...which is not to say that plastic sheeting is a bad idea.
