It is apparent that the low density of plastic is a problem, tins and cans can be squashed down and a) The stay squashed, and b) They are made of a dense material. BUT plastic is springy and low density, and always wants to return to its original shape, this is a problem, would it not be possible to shrink the plastic using heat? When you throw a crisp packet on the fire it shrivels right up to practically nothing before it starts to burn, would this concept work with the of a HDPE milk container? Why not reuse plastic bottles for something, you could fill them full of recycled aggregate and use them in Gambian style boxes? Or why not switch to glass and run a deposit scheme?
