About Chemical Recycling

Chemical recycling is emerging as a transformative solution for managing plastic waste, complementing traditional mechanical methods and addressing limitations in recycling complex or contaminated materials. By breaking down polymers into molecular components, it enables the production of virgin-quality feedstocks, reduces reliance on fossil resources, and supports circular economy goals

Objectives of the Forum 

  • demonstrate economic feasibility and environmental benefits
  • present and discuss case studies and success stories
  • enable the industry to create value from currently undervalued waste streams
  • promote knowledge, networks, and R&D projects
  • enhance circularity and climate protection by reducing waste and CO2 emissions
