Plastic Recycling TRIZ Cases

A washing unit combines turbulent blade stirring with centrifugal separation to detach contaminants from plastic pieces.

A plastic reduction device integrates air inlets and outlets for convection drying during comminution.

Vacuum spray separation condenses expanded polystyrene into dense liquid solution, reducing landfill volume and recovering solvent.

Pulsating water separates mixed plastic fragments by density, preventing re-floating for high purity recycling.

A single-stage plastic recycling device integrates shredding, grinding, and pulverization blades into one processing chamber for uniform output.

A rotary impact separator removes debris from mixed plastic and paper streams using mechanical abrasion and airflow classification.

Additives modify molecular structure of recycled HDPE during extrusion, resolving quality inconsistencies from mixed waste streams.

A cryogenic processing system shatters specific polymer components below their glass transition temperatures to enable material recovery.

Hydrolysis of rBHET with water adjusts hydroxyl to carboxyl end group ratios in oligomeric PET substrates.

Hydrolyzing biodegradable polyester mixtures above melting points using supercritical carbon dioxide to recover monomers for new polymer production.

P-Phenylene diamine agents break down sulfur cross-links without generating odors or degrading polymer chains.

On-board voltage regulator converts external supply to precise local levels, resolving complexity in mixed DRAM generation upgrades.
