Solutions to plastics problem - 1 & 2

Anything done to the plastics is better than that they litter the environment, so the primary problem is their presently poor collection especially in some countries. That could be very easily solved by giving a small token for any plastic taken to waste collecting units. If they don't exist, their generation could be a primary target of developmental aid. The collected plastic could then be used:

1. Plastics use for energy production. Since plastics are made of oil, they could be used for producing energy instead usiage of oil. In the simplest case, this would just mean burning plastic waste to produce energy for heating instead of burning oil. In a more advanced case, plastic waste is processed so that its molecules can be used as part of car fuels. Such processing is already done by some oil refineries.

2. Use of plastics as part of road paving. If the durable waste plastic is ground, it can be mixed to asphalt and used for paving of roads. The asphalt containing plastic particles can be even more durable than asphalt without them.

Naturally these choices do not decrease the carbon dioxide formed by the use of fossil fuels or the formation of microplastic particles from the wear of asphalt or tyres, but it does not increase it either, since microplastic particles are similarly produced from asphalt without added waste plastics. These problems will be resolved only after complete stop of fossil fuel use for energy production and replacement of asphalt in road paving.
