R&D as a core pillar for driving commercial success in chemical recycling

Itero present their three step approach to research and development to ensure the success of its chemical recycling technology. Starting with core chemistry, Itero have built upon their expertise in pyrolysis of polymers by processing real waste, studying both the chemical and physical attributes. Beyond this, operation of a full scale R&D facility at Brightlands will drive commercial success.

Xycle – The missing piece of the puzzle in solving the plastic waste problem

Xycle is ready to build its first Dutch plant to convert end-of-life plastics into high grade cracker feedstock. 20 Ktons waste plastics per annum will be converted into 18 million litres liquid hydrocarbons (pyrolysis oil).
The Business is based on proven technology (TRL-level 9) and is operational on various sites in Asia.

Designing plastics packaging for chemical recycling

by Christine Leveque, Director Business Innovation, Suez

There is a a widespread belief that Chemical Recycling processes allow to recycle the mechanically unrecyclable mixed polymer packaging. However thermo-chemical processes like Pyrolysis also need quality feedstock to produce quality oil !

The presentation will explain why it is essential for the circularity of plastics to continue the industry efforts in redesigning multi-polymers into mono-polymer packaging.

Chemical Recycling of Plastic Waste – Pyrolysis and downstream processing of pyrolysis oils

alexander hofmann conference

by Alexander Hofman, Fraunhofer UMSICHT

The recycling of many plastic waste streams like mixed plastics, composites or plastics with inorganic and organic contaminations remains very challenging. As an addition to mechanical recycling, chemical recycling offers the chance for closing the plastic recycling loop. Currently, great amounts of plastics are still incinerated and removed from this loop.

Is it possible to turn plastic waste into new plastic in a sustainable way?

Waste plastic can be turned into new plastics competing with plastics made from virgin fossil oil via pyrolysis /chemical recycling. This will change the current recycling value chain into a new sustainable ecosystem.

The new ecosystems contains the following steps in the materials cycle:

  • End of life Plastic Waste Stream Collection
  • Cleaning, Sorting and Separation
  • Recycling
    • Chemical recycling
    • Thermal and Thermochemical recycling / Pyrolysis
  • Processing of recycled materials (plastics and chemicals)
  • Production of recycled plastic materials
  • Reuse of the newly created plastics in applications
  • End of life plastic waste stream collection

What is chemical recycling / pyrolysis?

Chemical recycling today often refers to technologies that can be classed depending on the level at which they break down the plastic waste. Concretely, the technologies can be divided into 3 types:

  • Solvent-based purification. Comprises technologies that go down to the polymer stage. They are capable of decontaminating the plastic but cannot address its degradation. They work only with monostreams (PVC, PS, PE, PP).
  • Chemical depolymerisation. Chemical process which turns the plastics back into their monomers. Allows for decontamination but not addressing degradation. Only works with monostreams (PET, PU, PA, PLA, PC, PHA, PEF).
  • Thermal depolymerisation and cracking (pyrolysis and gasification) are energy-intensive processes which turn the polymers back into simpler molecules. They are capable of decontaminating polymers and, by bringing plastic back to its original building blocks, addressing the degradation of the material. These technologies can deal with more than one monomer at a time and are also capable of producing fuels. This raises the need for strict regulatory controls to prevent plastic being turned into fuel in lieu of recycling.
