Plastic Recycling TRIZ Cases

Heterophasic polypropylene compatibilizers resolve phase incompatibility in recycled PP-PE blends, achieving high stiffness and impact strength.

Sound energy agitates solvent in a container to strip resin from cut-off waste fibers, recovering reusable material.

Mid-infrared spectroscopy with chemometric calibration identifies conventional, high resilience, and viscoelastic foam types for accurate chemical recycling.

Controlling molecular weight and hydroxyl number of recycled polyol maintains foam quality despite high recycled content.

A thermoset precursor composition uses imine bonds to form cross-links with epoxy groups, enabling material recycling through solvent dissolution.

Optimizes crystalline and soluble fractions in recycled polypropylene to achieve high gloss while minimizing black spot contamination.

Dry anaerobic fermentation extracts rubber from plant material using minimal water, avoiding the high consumption of wet methods.

Molten Lewis bases depolymerize fiber reinforced polymers, recovering high-quality carbon fibers without the mechanical damage caused by grinding.

Melt-mixing recycled polypropylene with heterophasic copolymers balances impact strength and tiger stripe aesthetic quality.

Heated water baths re-crystallize PET to overcome high melting points, while centrifuges remove moisture for quality extrusion.

Temperature-controlled dissolution of polyolefins in n-alkanes recovers defined molecular weight fractions without high-pressure equipment.

Polycarbonate and polyethylene terephthalate blend excludes isophthalic acid to boost Vicat softening point.

Thermal contraction of copolymerized polyester film separates inks and films during regeneration, preventing chip clumping and discoloration.
