Around Hötorget, Vasaparken, and several other places in Stockholm, smart bins are deployed. By December 2016, there were 153 of them.
The so-called Big Belly-waste baskets are fitted with solar-powered software, mobile devices and sensors that report in real time when they are about to become full and it is time for emptying. They also have built-in technology that packs the waste.
Regular bins need to be emptied 1–3 times per day. As the smart bins are solar powered and packs the waste, they only need to be emptied four times a week. This means fewer garbage collection runs, lower costs and reduced emissions.
