Paper waste recycling (pulp recovery) process
- Dissociation process
- - While impacting the coated paper waste with the impeller in the pulper (maintained at about 50°C), dissociate it with aqueous caustic soda solution and recover it as a slurry-type pulp (requires complete removal of the coating layer within 1 hour, which is economic
International standard for recyclability (pulp recovery) evaluation
- UL2485
- If the pulp is recovered after passing the dissociation process selected among the TAPPI 274, TAPPI 275, and TAPPI 278 standards and the amount of components (rejects) such as the coating layer removed is less than 15% by weight, it is judged to be recyclable (established in 2018)
Example of UL2485 recyclability determination according to composition and dissociation performance of coated paper sample
| Developed coated paper composition (wt%) | Composition after passing the dissociation process (wt%) | Pulp recycling yield (%) | UL2485 certified | ||
|---|---|---|---|---|---|
| coating layer | paper (pulp) | Rejects | pulp | ||
| 20 | 80 | 20 | 80 | 100 | fail |
| 13 | 87 | 13 | 87 | 100 | pass |
| 10 | 90 | 18 | 82 | 91 | fail |
Recyclability evaluation(ECO CIRCLE PLUS)
Recyclability evaluation by UL2485 certified organization FPInnovations (Canada)
| division | Developed coated paper composition (wt%) | Composition after passing the dissociation process (wt%) | Pulp recycling yield (%) | UL2485 certified | ||
|---|---|---|---|---|---|---|
| coating layer | paper(pulp) | Rejects | pulp | |||
| Inorganic filled polymer composite (new material) coated paper (developed product) | 6 | 94 | 6 | 94 | 100 | pass |
| Polyethylene coated paper (comparative product) | 8 ~ 13 | 87 ~ 92 | 25 ~ 35 | 65 ~ 75 | 70 ~ 80 | fail |
-
Polyethylene coated paper
The pulp dissociation rate is slow as the flexible polyethylene coating layer is attached within a short dissociation time. -
Developed new material coated paper
The pulp dissociation rate is very fast and cleanly removed as the coating layer of the hard inorganic material-filled polymer composite (new material) is broken within a short dissociation time
Waterproof and oil-proof
No leaks or squishy even after 1 hour after filling with water with ink
No oil leakage or squishy even after 1 hour after filling with cooking oil
Microwave compatibility (heat resistance)
Food safety evaluation after processing paper containers at 700W in a microwave for 2 minutes
Heat-resistance/Stain-resistance
