Buy unpackaged goods
In photos, unpacked shopping looks like this: A row of preserving jars with bottled food is on a shelf. This not only looks great, but also gives you an overview of the food supplies. And if you keep the jars for a long time, it is also environmentally friendly in the long run. It's even better if you save disposable glasses from recycling and use them as storage jars.
Glass containers have one disadvantage, though: they're quite heavy. Transportation by cargo bike or by car may still be possible, but the latter is not really sustainable. For inexperienced people, however, shopping on foot will be a burden. And if you are not allowed to carry heavy loads for health reasons, a bulk purchase with glass containers will be impossible.
For the purchase of dry food, it is best to use cloth bags or paper bags. The paper bags from the fruit and vegetable department are perfect. The following applies: always use the bags several times, because the production of bags from kraft paper consumes a lot of resources. Also use bags in which flour, coffee or tea is sold several times. All variants are quite robust, light and foldable to save space, so you can reuse them often.
Pro-Tip: Write the contents and empty weight on the bags and put them in your pocket or backpack. Done. This way you are well prepared for spontaneous purchases, reduce your packaging waste noticeably and save resources.
