The Problem:
The increasing generation of plastic waste, such as polystyrene (PS), polymethyl methacrylate (PMMA), and polyvinyl chloride (PVC), poses an environmental challenge. Traditional methods for managing plastic waste (e.g. landfilling and incineration), have drawbacks such as environmental pollution and limited resource recovery. Mechanical and chemical recycling methods, although promising, can be energy intensive, have toxicity concerns, and are incompatible with emerging technologies, like 3D printing, highlighting the need for innovative solutions in plastic waste recycling/upcycling.
The Solution:
Researchers at the University of Alabama have developed new types of glycerol-based monomers that also act as a green solvent, effectively dissolving PS, PMMA, PVC, and other plastics at low temperatures. These novel monomers, synthesized from renewable resources, address environmental concerns and can open new possibilities for recycling and repurposing. They utilize photopolymerization to create polymers from smaller monomers. Their application in stereolithography (SLA) 3D printing highlights their versatility and potential in advanced manufacturing.
