Soft plastics can be recycled, but the (trained) labour to sort is prohibitively expensive.

Tyres can also be recycled, but the labour liability makes them prohibitively expensive in first-world-countries.

They can also both also be processed as Biochar, but the environmental cost is also prohibitively expensive: tyres result in Sulfur-contaminated charcoal and soft plastics are not the most efficient material to convert into charcoal.
