Waste Processing TRIZ Cases
- Spent Catalyst Metal Recovery via Low-Temperature Alkaline Leaching
Low-temperature alkaline leaching recovers valuable metals from spent catalysts without generating harmful gases or requiring high energy input.
- Cellulose Recycling from Blended Textile Waste
Hydrolyzing agents degrade polyester contaminants at 100-200°C, resolving the contradiction between recycling efficiency and fiber quality.
- Organic Acid Recovery from Superabsorbent Polymer Inactivation
Recovering organic acid from inactivation aqueous solution via polymer removal and pH adjustment.
- Mechanical Separation of Mixed Solid Waste Streams
Mechanical separation systems divide mixed solid waste into distinct wet organic, dry organic, and inorganic streams for targeted processing.
- Chemical Recycling of PET Dry Fines via Depolymerization
A chemical recycling facility depolymerizes PET-containing dry fines into recoverable plastics and chemical intermediates.
- Cyclonic Plasma Melting Furnace Asymmetric Torch Placement
Asymmetric plasma torch placement in a cyclonic melting furnace resolves the trade-off between processing efficiency and device complexity.
