In Italy, I have seen that only compostable plastic bags are used by the wholesalers there. Why doesn't Migros imitate this? You could then use the bags for collecting green waste.

I think that would be a great idea. I know them from Sweden as "Robbydogsäckli"?
A very good idea!!?
Such bags are already being used in Switzerland too!
At Fressnapf they give them out at the checkout for purchases?

Hello everyone
Thank you very much for this suggestion and your messages. I'll be happy to pass this on to those responsible - I think the topic has even come up before. However, I'm not sure what the current status is, so I'll get back to you when I've received feedback from our professionals.
Kind regards

Hello everyone
It really is as you thought - we have already looked very closely at the subject of compostable waste bags.
We have also calculated the life cycle assessments. The results of these life cycle assessments have shown us that biodegradable plastics based on corn and sugar cane, for example, do not perform any better than conventional plastics, even though they are mostly made from renewable raw materials and are compostable.
As a life cycle assessment from 2014 shows, biodegradable and compostable bags have a significantly higher overall environmental impact than petroleum-based bags. The reasons for this lie in particular in cultivation (intensive agriculture, monocultures) and higher material consumption for the same load-bearing capacity. Composting the bag also has no environmental benefit (little material recovery and no nutrients for the soil).
Another problem is that biodegradable materials sometimes compete with food production. For example, bioplastics are made from corn, potato or soy starch, which is an important source of food for many people.
For the reasons mentioned above, the use of biodegradable plastic bags is not an option for us at the moment.
I hope you understand this.
Kind regards
