Catalytic Upcycling of Polyolefins
Chemical ReviewsThe large production volumes of commodity polyolefins (specifically, polyethylene, polypropylene, polystyrene, and poly(vinyl chloride)), in conjunction with their low unit values and multitude of short-term uses, have resulted in a significant and pressing waste management challenge. Only a small fraction of these polyolefins is currently mechanically

Performance Evaluation of Compression‐Molded Recycled Mixed Plastic Fractions From Light Packaging
Polymer Engineering &Science, EarlyView.Mixed HDPE/PP bottle‐cap waste was successfully processed through closed‐loop mechanical recycling. The recycled blends maintained stable thermal, rheological, and mechanical performance over multiple cycles, demonstrating the feasibility of valorizing heterogeneous polyolefin waste without advanced polymer separation.

Polymer International, EarlyView.An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Aggregation‐induced enhanced emission for quantification of recycled content in automotive plastics
Polymer International, EarlyView.Quantifying recycled content in four automotive plastics using aggregation‐induced enhanced emission showed that performance was highly dependent on both polymer and additive chemistries. Abstract The use of plastics in the automotive industry is increasing due to their versatility, light weight and affordability.
