Environmental challenge(s) met
Waste Management

Outline of project:
Facing insufficient numbers of public waste bins, increases in littering and low recycling rates; South Korea's capital city Seoul was facing issues with infrequent waste collection and overflowing waste containers.

With the limited number of bins around the City requiring frequent emptying, the Seoul Metropolitan Government were facing a serious waste disposal issue. To exacerbate the problem, the Government didn't know how quickly the bins were filling up making it difficult to plan an effective waste collection strategy. In order to tackle this problem and improve Seoul's cityscape, Seoul municipality installed 85 Clean Cube bins around the city to facilitate the disposal of general and recyclable waste in particularly busy parts of the City.

Each Clean Cube bin is connected using IoT (Internet of Things) technology and is able to send out a signal to Seoul's Public Cleanliness Department via their Clean City Network. This alerts the waste collection team when the bins need to be emptied, allowing for an efficient collection schedule to be set up which, means the bins can now be emptied before they overflow.
