China had an amazing glass yoghurt bottle system until about 15 years ago. Foil caps were the only waste. Now it's all plastic. On the plus side, most people walk/cycle/e-bike to wet markets due to density, which means less horrible carparks, road noise and air pollution and ore walkable cities. It also encourages frequent visits which increases exercise, discourages over-purchasing and waste due to ingredient expiry, and creates a social element of banter to purchasing. Being cash free (most people pay by mobile phone) is undoubtedly improving things in terms of food safety. (Cash is super dirty!)

Quite positively, in Australia it's now frowned upon to use plastic bags and most people bring reusable bags to the supermarket. Unfortunately, this doesn't stop producers bagging a lot of produce in horrible plastic nets or bags before it even reaches the supermarket. Others, such as mushrooms producers, simply box their product and consumers are provided paper bags in which to pack their selection. I wonder why they don't just paper bag the whole fresh produce area, it'd surely be a huge step forward.
