Plastic Recycling TRIZ Cases

UV-excited delayed luminescence and predictive sensing sort plastic types and colors with high accuracy while reducing waste and energy use.

Hydroxyl fatty acid ester improves resin flowability while maintaining shock resistance.

Porous carbon compatibilizer, pre-crystallization, and solid-state polymerization improve mixed PET blend recycling.

Dichloromethane treatment filters dyes, dirt, and foreign polymers before recycling, reducing downstream purification and waste.

This case combines post-industrial recycled and virgin polymer in extruded film to retain strength, sealability, and printability.

A polypropylene resin blend balances recycled content with consistent expansion, closed cells, and improved molded-bead appearance.

Direct scrap overlap and resin curing reduce composite waste while retaining strength.

This case uses calcium hydroxide at 80–240°C to recycle polyester into reusable molecules while protecting cotton and other natural fibers.

Melt-mixed polycarbonate blends balance scratch resistance, impact strength, thermal resistance, recycled content, and high melt flow.

Demetra oxidizes and depolymerizes untreated polyethylene in a few hours, avoiding aggressive pre-treatment and reducing energy demands.

This masterbatch embeds enzymes or microorganisms in a carrier to support polymer degradation through industrial plastic processing.

A polycarbonate blend with aromatic polyester and inorganic filler balances strength, moldability, and resistance to thermal deformation.

This case combines catalytic aminolysis with water hydrolysis to recover amines and polyols without high-pressure hydrolysis equipment.

One-step catalyst processing improves hue and properties in recycled polyester elastomers.

This case replaces costly dissolution or monomer decomposition with solvent swelling to recover polymer fine particles.

This case uses fungal metabolites to partially depolymerize polymers, supporting mixed-material recycling without sterile conditions.

This case uses formula (I) stabilizers such as cysteine to preserve polylactide molecular weight and viscosity during melt processing.

Controlled screw kneading recycles polyolefin-rich laminates without layer separation, while antioxidants and low pressure limit burning.

Self-crosslinking acrylic and polyurethane inks resist dissolution, preventing staining during recycled PET flake processing.

Pre-heating solid polyurethane articles and mixing them with toluene diisocyanate supports continuous liquid pre-polymer production.

Controlled magnesium, sodium, and phosphorus compounds limit aggregation in high-recycled-content PET film, reducing pinholes and haze.

Controlled screw speed and ejection pressure recycle polyolefin laminates without separating their individual layers.

A recycled and virgin PET chip blend balances film processability, breaking strength, elongation, and thermal shrinkage.
