Since this conference is part of the Sustainable Materials series, speakers of this conference are being interviewed on JakajimaTV, the online TV channel of Jakajima on Youtube.
Maurizio Crippa is CEO of Gr3n and will be speaking at the chemical recycling session during the conference.

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.

Europe is at a crossroads for the way it manages plastic, plastic waste, and plastic waste trade. Plastic and plastic waste is traded worldwide. Exports from the EU to Asia have been a means to deal with insufficient recycling capacities in the EU. Waste import restrictions in China and Hong Kong have triggered a shift of exports to other countries.
Since some types of plastic waste have been added to the UN Basel Convention, the option of exporting plastic waste is becoming increasingly difficult, requiring to build a more robust and circular economy for plastic in Europe.

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.

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
- 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
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:
Continue reading “What is chemical recycling / pyrolysis?”
- 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.
