I assume my plastic recycling is what my council states - that it is burned (with the exhaust passing through scrubbers) to produce steam which is used to heat local businesses and public buildings, and generate a small amount of electricty, then the melted slag is collected and used as an asphalt replacement in road maintenance. It seems fair enough, maybe not ideal, but it generates some extra use from the waste.
