There is something funny in this common corporatist argument trying to get rid of responsibility by saying that "we just produce and sell what our customers demand". Namely, for some reason any proposal that would somehow increase the requirements for the corporations to disclose what, exactly, they are selling and how, exactly, that is produced, is vehemently opposed by the very same corporations.
To me, either you give full an unbiased disclosure about your products so that the customers can make their minds properly, or the ethics of your supply chain is your problem, not your customers. You just can't cherrypick here.

Plenty of cans are collected by homeless / lowest income people, but it's also just about enough that average people will collect them too.
If I have a huge bag after a party, I return them. When I normally only have 0-2 bottles in a typical week, I take them outside and put them on the little shelf on the bin for someone to collect without needing to rummage: https://www.magasinetkbh.dk/sites/default/files/public/style...
New food packaging can only use recycled material collected in this way. The general household recycling is considered too dirty.
