The reverse vending machines are very usefull but they have only one disadvantage - they are "passive" objects ! It is an intersting challenge to attract more people for collecting used cans and bottles.
A year ago I came to the idea of adding an outdoor arcade hardware to the "passive" vending machine.

In order to remove any sanitary problems cased by endless COVID pandemic I used my next idea of the foot-operated game controller.Below you can see the 2nd prototype under construction.
The core idea was to use kid's natural interest to gaming for extra profit.
But the same interest may be used in the Revers Vending!
The classic arcade gaming is almost completely killed by COVID and there is a clearly seen deficite of COVID-safe public gaming. There is no problem to use my old approach in the case of reverse vinding. Kids and teenagers have a lot of free time but limited pocket money. What if there will be a choice to get a set of competitive arcade game in addition to some kind of coupons for used plastic bottle and meta cans? As kids have a lot of free time they can use it fot colecting used cans and bottles and convert then into gaming with friends.
Classic vending and reverse vending machines may be installed at the same location and acts as main attractive element of the meeteing point for local youth.
Any transaction of vending or reverse vending gives a chance to play arcade game. In the cheapist case video and sound of arcade game is broadcasted through local WiFi net and can be received not only by players ( with their mobile devices) but also by onlookers and by-standers.
I made several arcade games for my foot operated game controllers starting from dance game and soccer. The most fresh game is about beer bubbles:
For kids beer bubbles may be replaced with similar bubbles in Coke :).
