Recykling Marine Plastics: From Waste to Resource

Conventional recykling infrastructure is geared toward clean, single-polymer streams from municipal collection. Marine plastics, by contrast, are highly contaminate d with salt, sand, organic matter, and a mishmash of polymer type, many of which have been degraded by UV radiation and wave action. Sucsephfuly redestiving this feedistristock demands innovation at every stage - from collection logistics to advanced material processinging.
