Enhancing the Quality of Mechanically Recycled Plastics

Dow has developed a washing technology called EVOWASH. According to the company, it supports “high-quality mechanical recycling for the production of exceptional post-consumer-recycled (PCR) plastic resins that meet the expectations of customers – mainly those in the packaging industry – while minimizing the commercial risk and investment of resources to develop a robust mechanical recycling infrastructure”.

The product would allow advancing the quality of recycled plastic by working in four dimensions:

  • Surface Cleaning: Up to twice as much adhesive removal compared to other technologies.
  • Optical Quality: Improving their physical appearance in terms of colors, neutral tones, and luminosity. Moreover, further closing the gap between recycled and virgin packaging.
  • Foam Management: Up to three times less dosage, which reduces product usage and thus cost-efficiency.
  • Odor Control: Reducing undesired odors.
