Waste Processing TRIZ Cases
- Plastic Cleaning With Low-Dielectric Water for Oil Impurity Removal
Heated water with dielectric constant 60 or less removes oil stains and adsorbed impurities from plastic without solvent pollution.
- Covered Screen Bed Plastic Separation by Size and Density
Multi-stage screening and gravity separation sort mixed shredder plastics by size and density to recover cleaner PP, PE, ABS, and PS streams.
- Recycled Resin Processing Using Vibration to Untangle Runner Waste
Vibration transport separates entangled runner-containing molding waste, improving recycled resin processing efficiency with limited added complexity.
- Photovoltaic Module Resin Removal With Controlled Oxygen Combustion
Controlled 6-15% oxygen and a transition metal oxide support remove PV module resin without soot, enabling stable continuous recovery.
