These are called "reverse vending machines." They are a pain in the ass though because they are always filling up and/or jamming and then you have to call and wait for staff to come fix it. If you are redeeming a whole cart of bottles you're going to have to call the staff over at least a couples times. They are always in use so you have to wait. The rooms they are in are nasty and sticky. The bar code reader doesn't always work the first time (and sometimes doesn't work at all for some bottles) so you're constantly refeeding them into the machine. They get a TON of use, so they go out of order frequently. My grocery store just got brand new ones and they are better than the last ones they had still have problems.
