Paragraph starter
The end-of-life management of plastic waste is a critical consideration for sustainable product design. While mechanical recycling has limitations, chemical recycling technologies offer a promising avenue for processing mixed or contaminated plastics into valuable feedstocks (Li et al., 2022). This approach aligns with circular economy principles by reducing reliance on virgin resources and mitigating environmental pollution. Therefore, designing products with materials amenable to chemical recycling, or designing for easier disassembly to facilitate this process, represents a forward-thinking approach to minimize environmental impact.
