The future of plastics is undergoing a paradigm shift from a linear "take-make-waste" model to a circular, molecular economy. While current trajectories suggest plastic pollution could double by 2040 without intervention, a "System Transformation" integrating reduction, reuse, and advanced technology could cut pollution by 83% and reduce greenhouse gas emissions significantly.
Molecular and Enzymatic Recycling The industry is moving beyond mechanical recycling, which often degrades material quality, toward molecular recycling. A major 2025 breakthrough involves a single-site nickel catalyst that selectively depolymerizes polyolefins (PE, PP)—the most common plastics—into high-value oils and waxes. Unlike traditional methods, this catalyst operates at moderate temperatures and tolerates contaminants like PVC, potentially eliminating the need ...
