| Technology/benefitsPET Recycling: Required processing steps and main applications | When looking at classic PET bottle recycling, several “key steps” (see picture) are required for finally receiving quality secondary raw material, suitable for making high-quality products again. By using the Erema VACUREMA technology, different high-quality products can be produced. Two main applications have stood out from the rest in the past years: |
- BTB: Bottle-to-Bottle Recycling by using the “Double Step”-VACUREMA technology
- Inline Extrusion: Direct production (via extrusion) of products (sheet, strapping, fibre) from bottle flake, without detour of pelletising, by using the basic VACUREMA technology
In comparisn to conventional PET processing systems treating pellets after the extrusion, the patented VACUREMA process offers the following key advantages: | - Quicker and less energy-intensive IV increase by treating flake in comparisn with concepts treating pellet, since the infeed material into the VACUREMA reactor in the form of (typical) bottle flake has much thinner wall thickness compared to pellet and therefore a much larger surface.
|
- For the same reason as above, decontamination efficiency is higher and decontamination takes place quicker at a time.
- Due to the very effective predrying under vacuum IV of produced pellet is more stable and less sensitive to input flake moisture variations.
