Mixing of sand and plastic is the way…
We got in contact with a Rotterdam (NL) based plastic expert that had developed a process to mix plastic waste with sand. The results were amazingly strong and the machine he was using didn’t seem to ware from the sand-mixture that went through it. Some material samples looked quite good, if not impressive.
In Accra we had visited a company called Nelplast that does the same mixture and with equal impressive results. This is our proof that our assumption that adding sand to the plastic improves the quality is indeed true.
