Polyethylene, as the predominant polymer produced globally, poses significant environmental challenges due to its resistance natural decomposition. In this study, we introduce an innovative chemicalbiological approach for transforming waste polyethylene into valuable biosurfactants. Our method involves hydrogenolysis using specially designed Ru/CeO2 catalysts, which efficiently convert alkanes while keeping methane selectivity below 5 %. This optimization ensures maximum feed availability subsequent microbial processes. Notably, chemical intermediates are directly utilized in biological phase, eliminating need intermediate processing. Gordonia sp. JW21, selected exceptional alkane degradation capabilities, metabolizes a wide range of structures, including extended alkyl chains. The process culminates generation high-value synergistic strategy not only offers effective solution management but also sets precedent sustainable production

The large production volumes of commodity polyolefins (specifically, polyethylene, polypropylene, polystyrene, and poly(vinyl chloride)), in conjunction with their low unit values multitude short-term uses, have resulted a significant pressing waste management challenge. Only small fraction these is currently mechanically recycled, the rest being incinerated, accumulating landfills, or leaking into natural environment. Since are energy-rich materials, there considerable interest recouping some chemical value while simultaneously motivating more responsible end-of-life management. An emerging strategy catalytic depolymerization, which portion C-C bonds polyolefin backbone broken assistance catalyst and, cases, additional molecule reagents. When products molecules materials higher own right, as feedstocks, process called upcycling. This review summarizes recent progress for four major upcycling strategies: hydrogenolysis, (hydro)cracking, tandem processes involving metathesis, selective oxidation. Key considerations include macromolecular reaction mechanisms relative to mechanisms, design transformations, effect conditions on product selectivity. Metrics describing critically evaluated, an outlook future advances described.
