Armed with trash bags and snazzy-looking smart trash grabbers, aka “ rubbish beams “, the rubbishers have picked up over 130,000 individual pieces of litter over the course of almost a year of regular street cleanings in San Francisco — collecting data all the while on what, where, and when.

By relying on Firebase to store, process, and analyze an increasing amount of data, we feel confident that we can engage and empower individuals, communities, and governments to tackle extensive, seemingly unsolvable problems like litter.
