Solar or wind or sea energy add find cheap aid, providing discontinous use of nearby availability during idle times. Not a large spot, but opportunities of use as much as there are markets for food and varieties of packaging waste! All together. It might have sense.

The resulting material has provided good mechanical properties better or comparable to concrete or wood for use at local meteo conditions, density, compression resistance, surface hardness, water resistance, workability of nailing and screw application of joints with other materials…

The idea came out by a senior chem engineer migrated to France with his family from the Hungarian repression imposed by the relevant policies, lasting from 23 October until 10 November 1956. It was object of a patent, not exploited in continental Europe, largely considered by Japanese industry interested to apply appropriate large mixers sizes to comply road constructions technologies… during the ’70s. The original patent claims were relevant for the expoitation of unwashed sea sands and the destination of thermoplastic polymers (inclusive of u-PVC), which were economic competitors free delivered to the spot as is at the collection, without the preliminary need to invest for selection and contamination risks.

Try and create on the spot! It’s easy to mix the wide variety of plastic to sand ratios with any heat available to soften the polymers ligand with the fillers… until an acceptable degree of dispersion!
