I wonder about supermarket food in particular. Most of it comes in at least one layer of single use plastic - I think plastic can be the right product, but it would need reusable plastics that are standardised and used across different companies products. A bit like how nearly all Chinese takeaways use a variant of a cheap but reusable plastic container (but they're not quite standardised, particularly the radius of the lid corners).
I'd love to see say 20 different allowed packages, you return after use, they're cleaned (or recycled if damaged), and used for more food. No more half full tubs carefully concealed with labels!
I wonder what the stats say vs GPs impressions of Austin?
