Mechanical vs Chemical Recycling Comparison
Understanding the differences between mechanical and chemical recycling helps manufacturers choose the right solution for their sustainability goals.
Mechanical Recycling
- Process: Shredding, washing, melting
- Output: Downcycled materials
- Input: Clean, sorted plastics
- Cost: Lower
- Energy: Less intensive
Chemical Recycling
- Process: Depolymerization, pyrolysis
- Output: Virgin-equivalent materials
- Input: Mixed, contaminated plastics
- Cost: Higher
- Energy: More intensive
Comparison Table
- Input Quality: Mechanical requires clean, Chemical handles mixed
- Output Quality: Chemical produces virgin-quality
- Cost Efficiency: Mechanical is more cost-effective
- Scale: Mechanical has larger scale currently
Conclusion
Both technologies are complementary and essential for achieving true circular economy for plastics.
