Hot molten plastic and sand mixing; for disposal or re-moulding.
Plastic and Sand Mixture
I raised this idea recently in the conversation started by Julie Nawfal “How can we improve Plastic Recycling?” The idea involves the building of industrial plastic recycling centres, to be located upon the shores, of very hot “sun-drenched” coastal regions, with additional shipping ports.
These centres would have very large elevated metal melting vats, preferably made of heat conducting copper or/and with heat conducting rods passing through the lower part of the melting vat.
The heat supply needed to melt the flaked plastic, would be gained from the sun, using multiple concave solar mirrors, to focus the rays of the sun onto the external surface of the heat conducting rods.
Below this vat; industrial sized mixing machinery would serve to mix the molten plastic and sand, (Or e.g. crushed concrete and brick etc. from construction sites); and the resultant sand and plastic mixture, would then moulded into blocks heavy enough, to be sunk down into the oceanic trenches, or other areas of the deepest parts of the oceans, which are several kilometres deep and quiet and still, with no current to cause plastic erosion.
However given human innovation, ideas, and inventiveness; this mixture could be used to e.g. build artificial reefs incorporating wire mesh, to allow coral to grow over them, and so isolate them from the ocean; blocks made from this material could be used to build sea walls (In the face of rising sea levels) or foundation slabs for construction etc. etc. the list of ideas being only limited by the human imagination; the input of which, is the purpose of this conversation.
