  • Depolymerization Technology Chemical Recycling Guide

    Depolymerization Technology Chemical Recycling Guide

    Depolymerization breaks polymers into monomers for virgin-quality recycled materials, enabling true circular economy for plastics that mechanical recycling cannot process.

    Technology Types

    Methanolysis

    For PET recycling. Produces DMT (Dimethyl Terephthalate) and EG (Ethylene Glycol). Commercially established with major players including Eastman.

    Hydrolysis

    For PA (Nylon) and PET. Water-based depolymerization at elevated temperature and pressure. Higher energy requirements but handles mixed inputs.

    Glycolysis

    For PET and polyurethane. Uses glycol to break polymer bonds. Lower severity conditions, suitable for certain waste streams.

    Enzymatic

    For PET. Uses enzymes (cutinases) to break polymer at mild temperatures. Emerging technology with commercial-scale demonstrations.

    Applications

    • Bottle-to-bottle recycling maintaining food-grade quality
    • Nylon carpet recycling to monomer feedstocks
    • Polycarbonate waste conversion to BPA

    Commercial Status

    Several commercial plants operational and under construction. Eastman, Loop Industries, and jeplan lead commercialization efforts.

    Economic Considerations

    Capital costs higher than mechanical recycling. Operating costs depend on energy prices. Virgin-quality outputs command premium pricing.
