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.

  • Jan 8 2014: Hi, I think this would be a good initiative, In the purpose of recycling and giving back to earth, have you ever heard of hot water stream, bringing plastic into the same area in the ocean, maybe it would be a good idea to get this plastic to be moulded as something useful
  • Jan 9 2014: Hi, you might be interested by the work of this guy, Dave Hakkens

    • Jan 9 2014: Hi Christopher

      Great thanks a lot just had a look through it, and it is certainly very interesting, and eye opening in regard to the issues related to plastic recycling, and I hope everyone who joins this conversation takes a look at it.

      It is also great to know that there are people around like Dave Hakkens, who have such a commitment to both developing and finding ways of dealing with an ever growing problem; that is in the process. of rapidly choking, and killing all forms of life throughout the natural kingdom.

      And which in conjunction with oceanic petrochemical pollution + oceanic acidification + industrial and domestic heated effluents = increased oceanic heating + overfishing + Co2 and hydro-carbonic atmospheric pollution etc. etc., = environmental changes = climate changes = environmental changes = climate changes ad-nausea;

      Is currently the unstoppable march of so called progress; that is "rapidly" taking, and pushing the unwitting masses, and climate change skeptics, towards their own extinction..

      You could say; that it will be the final plastic straw, that in the very near future, succeeds in finally breaking the Camels Back. And the pandemic state of the blissful ignorance, and skepticism of the masses, will finally meet face to face, with its most unforgiving adversary, and most powerful Nemesis "Nature".

  • Jan 9 2014: Hi Christopher

    Thank you for your positive response to the idea, and indeed I do mention these in the comment I made in the Julie Nawfal conversation "How can we improve plastic recycling" which she gave the thumbs up to; and I have just posted in this conversation, a couple of WWW. references that you, and others, may like to take a look at.

    A little later I shall also be expanding on the original idea as it is presented in the introduction, which is/was limited to 2000 words; in order to explain how the same process can be used, for recycling the plastic from electronic equipment, while at the same time serving to recover the precious metals from the electronic components, and so allowing them to be recycled, rather than wasted when disposed of in land fill.

    Thank you once again for your interest and positive response

    Cheers Carl

    Addendum: All ideas regarding collection from the environment, prevention of plastic pollution etc. etc. are welcome; as the conversation when it ends; will serve as a repository of ideas for others to reference.
