In the bag?

A little while ago I read that the French firm J&M Plast, part of the European packaging group Sphere, was turning to potato starch to make a new biodegradable plastic material for bin bags (unsurprisingly called ‘Bioplast’). L’Usine Nouvelle reports on it here - the link is in French but you’ll find an English version on Matthieu Fossoux’s blog. Biodegradable polymers are now widely investigated – starch-based polymers, polylactic acids (PLA) and polyhydroxyalkanoates (PHA), naturally produced by bacteria, being among the most promising.

Meanwhile, retailers are increasingly switching to a “pay per bag” policy. This has proved to be very effective in the past, with a reduction by 90% in plastic bag consumption in the Republic of Ireland, where customers have been charged per bag since 2002. The Swedish furniture manufacturer Ikea has also adopted a similar policy in the UK, and is reporting a massive 95% drop since last June. Ikea is now extending this scheme to the US and all the profits (with a limit of $1,750,000 within 12 months) are to be donated to the non-profit organization American Forests to plant trees and offset carbon dioxide emissions.

While too many shops still routinely give out plastic bags, these reports are certainly encouraging – and the great news is: we can all contribute.

If you want biodegradable polyethylene, add carbonyl groups (Norrish-type photochemistry). You are co-polymerizing to LLDP anyway.

Agriculture plus processing is an insanely expensive, messy, and inefficient way to make bulk chemical commodities. One imagines hunter-gatherer Enviro-whiners threw hissy fits over agriculture and animal husbandry (sustained to this day).

What is concerned is not only biodegradability but also the subsequent environmental effects of the degradation products. PLA is said to degrade into CO2 and H2O.

Good evening!
I came here by chance and fell on my name in this post. what an incredible surprise!!
Thank you for this link.
