Hi Garrett, really good idea. Diapers are definitely not something that is interesting to recyclers, and asume they never will be. Do your diapers need any special conditions (temperature, moisture, additives, etc) to break down?
The idea is that the connecting ring that the cap is attached to is loose fitting, so it would rotate with the cap. The challenge now is making a good enough seal with a PET on PET closure and how to change the bottling lines to attach a cap by screwing it on rather than pressing it down.
I didn't know about this development, thanks for sharing. As far as I understand from reading the article, this is definetely something that will have a huge impact when it comes to decoupling plastic production from fossil fuels and could be used in this or any PET application. What this does is instead of creating PET plastics from oil, you create the exact same material from other renewable sources such as plants and would be completely interchangeable with regular PET. We would still need to come up with ways to increase closed loop reycling rates.
