Eli5 why we can’t melt plastic down and use it to add to asphalt

647 views

I keep reading about how most plastic can’t be recycled and goes to the landfills instead.

With our technology, why can’t we melt it down, using some sort of scrubbers/filters to capture the emissions, and add it to asphalt or other industrial uses?

At the very least it seems like we could reuse that plastic for non food items that are typically used once and tossed.

Lots of people are already trying it. They’re considering things like microplastics and recycling and full lifecycle cost. It might take a couple of years until they know the results.
