TPS Process - A supercritical co2 technology to delaminate the materials from wastes

Food packaging's, clothes or shoes, solar panels, credit cards, skis etc... These are complex and technical objects composed of multiple layers of different materials. They are bound together to bring several required properties to the product (mechanical strength, oxygen barrier, hydrophobicity…). Taken separately, each material can often be well recycled or reused. But the separation process can be costly or sometimes impossible, especially when shredding processes are involved. The TPS process is an efficient, fast and sturdy technology based on existing industrial supercritical processes. The solvents used, coupled with supercritical CO2, allow delaminating the different layers of materials of the wastes (glues and bonds at the interface of materials are dissolved). The TPS process is a clean chemical process using mainly supercritical CO2 for the separation (delamination) of multi-layer complex wastes and products, to enable their recycling. Non-recyclable wastes can then become fully recyclable. TPS Process gives a new life to multi-layer complex wastes.

Key features

  • Separation of materials in a few tens of minutes
  • Fluids used in the process composed at more than 80% of CO2 which is recycled at more than 99% in a closed loop
  • More than 90% clean separation of recyclable materials
  • Between 50% and 90% of the materials from waste become recyclable
  • 25% less raw material usage in packaging


  • 18 month pay back upon raw material value
  • 100% raw material costs controlled thanks to recycling

Maturity Stage

  • Medium and large scale commercialization
  • Small scale commercialization
  • Initial market commercialization
