A Complete Transformation PAth for C-C backboned plastic wastes to high-value Chemicals and materials

Plastic pollution has become a clear threat to many environmental niches and ecosystems, due to rapidly increasing use of plastic products and leakage to the environment. Polyethylene (PE) is the most widely used and the largest-volume plastic (c.a. 30% of total plastics). Due to the absence of reactive groups, the C-C backboned plastics are often categorized as non-degradable; generally disposed by incineration or landfill (67%). About 12% plastic wastes are recycled as the goods with inferior quality and performance. The real catalytic route for upcycling of PE wastes into value-added products is 90%). Two separate systems: multi-enzyme machinery assembled in the recombinant cells, and metabolic engineered yeast system, dedicated to the transformation of alkanes into monomers will be developed. Monomers of diversified chain-lengths will be used for the synthesis of polyesters presenting different properties and polymer performances, assignable for various applications. A zero-waste solution to the plastic waste management is thus created to keep them out of the environment, and reclaim their values. The new properties and specific applications of the new polyester plastics produced from upcycling of PE waste will bring up the SMEs with new business opportunities by scalable, flexible and robust multi-product manufacturing processes for on-demand and small-volume output production.
