Yes expensive until you can drop by a local location and grind all the plastic scrap sitting around your house. Aka Coinstar, Redbox type service
until even that is obsolete as we can throw our old plastic in a portable grinder under the sink . We already have labels on nearly all plastic
materials that state what type of plastic that bottle is aka HDPE, PVC, PET, and even simpler it has a numbering system. Grind all your like number
plastic together...very simple. Finally we have a true reason to pick up the plastic bottles littering the side of the road. It is also just cause to
dig up the junk piles with all that buried plastic.
I saw this in the mid 90's at a start up company that washed soda bottles, milk jugs etc. and ground them down to powder. They even had chemicals that
could dissolve labels, glue, that were stuck to the plastic, also a chemical that floated off a limited amount of plastic contamination. There was an
experimental chemical also that could remove colorant from plastic but, would require a retooling of the process to add a melting step. The whole
process was nearly automated with one person just monitoring a computer.
The company did not last because they lost money trying to pay people to manually sort the plastic types in several locations. They also had
projections that in order to get the consumer to sort plastics ahead of time on a large scale they (consumers) would be grinding their own plastics
and making their own products at home. In other words their large scale project would become obsolete in a few years.
