A great project! Go on with it!

... for my part, I always bring my rucksack when I go shopping and look for reusable packaging. When there is no other option, I choose big packs instead of a bunch of small packs to at least reduce the waste.

Tip: instead of using a plastic straw, you can serve a XXL spaghetti noodle. (Available in different stores with a diameter of approx. 0.3 cm) 😉
