The smart Finbin® accessories increase the comfort and safety of using the bins. Equipping a bin with a recycling rack removes the need to manually separate cans and bottles; the recycling rack collects cans and bottles and allows these to be emptied directly into a bag. The bird guard prevents birds from accessing litter. There are different fastening options from steel and concrete bases to different types of racks that expand the functionality of litter bins and ashtrays.
