Case Study: Baltimore

Baltimore is giving residents new reasons to take pride in their city.

Baltimore, the largest city in Maryland with a metropolitan area population of 2.8 million, is taking bold steps to become a smart city of the future. Since September 2018 the city has deployed solar-powered CleanCUBEs to clean up its streets and go green. It has immediately seen a drastic drop in waste collections resulting in less fuel emissions and traffic congestion. And by using cloud software, city officials can optimize collection schedules and quickly identify unsightly overflow. Hoppers have also been equipped with wireless locks to prevent terrorism ahead of big events. Residents are enjoying safer and cleaner streets and finding renewed pride in the city’s image.

January 2019

SOLUTION

280 solar-powered compacting CleanCUBEs installed (for general waste)
28 non-compacting CleanCUBEs installed with CleanFLEX sensors inside (for recycling)
a possible deployment of thousands more under consideration
no more ambiguity, waste volume can now be analyzed online to identify areas with high waste generation so collection routes can be optimized

RESULT

collections dramatically reduced by 98.5% for compacting CleanCUBEs (general waste only) from twice a day per bin to an average of once a month
- waste volume down 97.7% from previous conservative estimates
- haulers can visually check bins with low levels and skip them saving time, fuel emissions, traffic congestion, and money
recycling monitored online so the city can measure its progress toward the State of Maryland’s mandate of recycling 35% of municipal waste; recycling volume is averaging 704 gallons per bin each month while collection frequency is down 74.3%
waste overflow incidents minimized to an average of once a day
online ability to lock hopper openings to ensure safety before large scale events
