A Cradle to an End-of-Life Solution for Billions of Plastic Containers
The article “LVF Introduces BreakdownPET, an End-of-Life Solution for Billions of Plastic Containers”  gave rise to the tile and headline of this post and our commentary.
DalinYebo Commentary (and Food For Thought):
The idea of BreakdownPET has some (temporary) merits. However the article is silent on two topics that came to our minds:
- Landfill bio-degradation of PET will result in breakdown products such as methane or (at best, if methane is recovered/converted to) CO2, the so called Greenhouse Gases, which in this case a derived from oil.
- Currently, more and more PET is recycled and re-used (e.g. up to 90% in India; see Wikipedia for the stats and other info) in e.g. in fabrics or shoes , which are not necessary items that one would like to bio-degrade!
Therefore, BreakdownPET and PET recycling are important, temporary measures. Besides finding alternate, eco-friendly substitutes for PET, there is only one solution: All Polyesters must be made from sugars (biomass) and not from oil! (from “PET Recycle & Reuse – Only an (Important) Interim Solution!“):
- Sugar-derived polyesters can also be recycled and re-used.
- Sugar-derived polyesters have superior physical properties.
- Sugar-derived polyesters are made from CO2 that is absorbed by plants and turned into bio-carbons (sugars) which then become the starting point of furan (furfural as well as 5-HMF) chemistry. Therefore, if a BreakdownPEF is made, the resulting greenhouse gases are at least derived from bio-mass
A brilliant carbon-capture of bio-based CO2!
