Chemical Recycling Technology Complete Guide
Chemical recycling represents the next generation of plastic recycling technology, capable of processing mixed and contaminated plastics that mechanical recycling cannot handle.
Technologies
Depolymerization
Breaks polymers into monomers for virgin-quality recycled materials. Applicable to PET, PA, PC, and PMMA.
Pyrolysis
Thermal decomposition in oxygen-free environment produces oil, gas, and char. Suitable for mixed plastics.
Solvolysis
Uses solvents to selectively dissolve and recover polymers. Enables high-purity material recovery.
Gasification
Converts plastics to syngas for chemical production or energy generation.
Comparison with Mechanical Recycling
| Aspect | Mechanical | Chemical |
|---|---|---|
| Input materials | Clean, sorted | Mixed, contaminated |
| Output quality | Downcycled | Virgin-equivalent |
| Energy requirement | Low | High |
| Cost | Low | Higher |
Market Outlook
Chemical recycling capacity expected to reach 8 million tons annually by 2030, driven by regulatory requirements and brand commitments.
Conclusion
Chemical recycling is essential for achieving true circular economy for plastics.
