Reverse vending machine

A reverse vending machine (RVM) is a machine that allows a person to insert a used or empty glass bottle, plastic bottle, or aluminum can in exchange for a reward. After inserting the recyclable item, it is then compacted, sorted, and analyzed according to the number of ounces, materials, and brand using the universal product code on the bottle or can.^[1] Once the item has been scanned and approved, it is then crushed and sorted into the proper storage space for the classified material.^[2] Upon processing the item, the machine rewards people with incentives, such as cash or coupons.^[2]

The first prototype of a reverse vending machine was established in 1972 by TOMRA.^[1] With nations increasingly adopting policies concerning recycling and sustainability, reverse vending machines have become the standard in areas with stringent recycling policies.^[1] To date, there are more than one hundred thousand RVMs spread globally, located in countries including the United Kingdom, Russia, Norway, Sweden, Australia, Canada, and the United States.^[1]
