Some of your Questions:
Why chemical recycling?
Only chemical recycling conforms to the principles of sustainable development because it leads to the formation of the raw materials from which PET is originally made. Chemical recycling utilizes processes such as hydrolysis, methanolysis, glycolysis, ammonolysis, and aminolysis.
Why Polyesters can be chemically recycled?
Polyester's chemical recycle is based on the concept of depolymerizing the condensation polymer through solvolysis chain cleavage into low molecular products which can be purified and reused as raw materials to produce high-quality chemical products.
What is the difference between chemical and mechanical recycling?
In the chemical recycling you obtain the monomers after a chemical reaction (among others hydrolysis, methanolysis, glycolysis), so you can produce new virgin PET without consuming natural sources with the same properties of the one produced using petrol. In the mechanical recycling the material is washed, chopped, melted and re-extruded, modifying at each step the physical-mechanical properties of the polymers itself.
Are chemical and mechanical recycling in contrast?
No, chemical and mechanical recycling should work together to obtain our goal: eliminate plastic waste issues on a global basis.
What is the difference between Gr3n process and other chemical recycling processes?
Our process is a closed loop process. The auxiliary chemicals needed for the reaction and for the work-up steps are in situ produced from the by-products. The production of chemicals is allowed by the ancillary systems/processes .
Is the chemical process environmentally friendly?
Our closed loop process requires only water and energy to work.
What is processed (2)
What is the feedstock source?
In our process we can use every kind of polyester bottles (e.g., colored, transparent, opaque) but also textile and mixtures of textiles (e.g., Polycotton, with cotton content up to 50%).
Is Gr3n depolymerizing just PET bottles?
No, we are not depolymerizing just bottles, because our process allows us to approach also textile and different type of polyester packaging.
