I mostly see them used for 1/2-gallon milk and small juice containers in the U.S. I’m in Canada right now and see them being used a lot for large juice containers also. I could see glass used for those (as they were in the past) but with the higher risk of breakage it’s not as ideal, but have a harder time picturing aluminum being used for milk and at least some of the more acidic juices. Does aluminum work with those beverages?
You seem informed on the subject: I’ve recently seen aluminum single-use cups advertised, targeting the same market as red plastic cups commonly seen at picnics. Those plastic cups are rarely recyclable, so I’m assuming the aluminum kind are more eco-friendly assuming they get recycled, even with high energy usage?
It might not qualify her for disability insurance, as in she no longer needs to work any jobs, but should absolutely entitle her to disability protections, as in job requirements should be modified to permit her to continue to work. If her employer is not making accommodations to permit her to continue to work then she might have a legal case.
