In Ukraine, there is a big French supermarket chain called Ашан (auchan.ua), in which people can buy liquid cleaning products by the volume. For example, if you need a litre for dishwashing cleaning soap, you can go and pull a lever and fill an appropriate size plastic bottle. It's their own brand and it's very cheap. I'm not 100% sure if you can bring and use any plastic bottle, or you have first get it from them.

They also have huge crates of pasta and other grains where you can simply shove how much you want into a plastic bag, weight it and pay at the till.

No need to wrap those items in boxes and more containers.

While Ukraine has many environmental problems (it's not easy or common to recycle, large % of uneducated population about these issues), it has some good ideas and policies like these.
