ClearOn technological solutions for recycling of recycling of polymer waste: A review
This paper is not directly about microplastics; it reviews technological approaches to recycling polymer waste — mechanical, chemical, and energy-based methods — and analyzes their economic and environmental trade-offs. Better plastic recycling technology is relevant to microplastic prevention insofar as it reduces the amount of plastic that degrades into environmental microplastic particles.
