​Instead of single use plastic bottles at grocery stores, there are just machines like soda machines to dispense everything like a gas pump.

So, you know how a single aisle of laundry detergent has almost 100+ bottles of detergent that will just end up in the oceans?

how about making massive machines, similar to how soda machines at fast food places work. The difference is you pay right there. You insert your card, place your bottle (empty bottles sold at 6-12 dollars if you forget one or damaged it), and it refills the bottle. OR instead of relying on a machine, the store just has one in the back where you give your jug to an employee, he fills it up, and you pay him how much he filled up.

Extend this to almost everything, including 2 liter bottles of soda. Cans are ok since ~65% of aluminum is recycled.

This would reduce plastic wastage by a lot and also help speed up pick up lines.
