Plastics play a vital role in modern society, but their accumulation landfills and the environment presents significant risks to ecosystems human health. In addition, discarding of plastic waste constitutes loss valuable material. While usual mechanical recycling method often results reduced material quality, chemical offers exciting opportunities valorize into compounds interest. Its versatility leans on broad horizon reactions applicable, such as hydrogenolysis, hydrolysis, alcoholysis, or aminolysis. The development heterogeneous supported organocatalysts has enormous potential enhance economic industrial viability these technologies, reducing cost process mitigating its global environmental impact. This review summarizes challenges chemically heteroatom-containing plastics through catalysis, covering widely used polyesters (notably PET PLA), BPA-polycarbonate (BPA-PC), polyurethane (PU), polyamide (PA), polyether. It examines limitations various solid catalysts, including clays, zeolites, metal–organic frameworks well immobilized enzymes (heterogeneous biocatalysts), for that facilitate recovery high-value products. By reintroducing products economy precursors, this approach supports more sustainable lifecycle plastics, aligning with principles circular economy.
