Plastic Waste Recycling

What is Plastic Waste Recycling?




The best for the environment is an integrated solution for the existing different plastic waste streams that works with all available recycling and recovery technologies. The selection of processes should be based on the combination of Life Cycle Assessments (LCA) and mass balances with a good overview of the carbon footprint for the complete process and should include the collection up to the process as well as the output as polymer, feedstock, electricity or replacement for fossil fuel.

Since 2018 the wide public has been provided by some associations, experts and environmental groups with incorrect information about the Solvent-based purification (Dissolution) in general and for the CreaSolv® Process especially, describing this plastic recycling technology as chemical recycling and/or solvolysis.

Solvent-based Purification (dissolution) is based on physical and not on chemical reactions or changes and only the physical state of the polymer changes from solid to liquid and then back to solid. The polymer chains remain unchanged in contrary to Chemical Recycling and can be re-used in the original or similar applications. Therefore, it can be no surprise that the dissolution meets the criteria of mechanical recycling but not the ones of chemical recycling.

Therefor we decided to offer a 2 minutes/day Training Course about the Basics of Plastic Recycling over a period of 15 days as LinkedIn posts and started the project on 11th March 2020 for all those, which might be interested in this subject.

In this training we address a few key questions, which are of critical importance when discussing plastic recycling technologies in order to compare their advantages and disadvantages.

•Physical or chemical reaction?
•Dissolution or solvolysis?
•Recycling or recovery?

The aim is to clarify, that
•Physical and chemical reactions are significantly different.
•A dissolution (solvent-based purification) is neither a chemical recovery nor a solvolysis.
•Chemical recycling needs the polymerization of feedstock to be complete.
•End-of-Life Treatment Cost need to be added to or included in the price of polymers and plastic articles in order to fund plastic waste collection and sorting followed by plastic waste recycling.
•Industry needs to develop plastic articles which can be recycled by all available plastic recycling technologies.

Specialization drives technical development.
This is not possible without knowledge, especially when coping with a complex problem.
