SINGAPORE — After a successful pilot for solar-panelled “smart” trash bins, industrial property developer JTC has put up more than 40 of these bins around the island.
The bins, called Bigbelly bins, have an internal compactor to crunch rubbish and can handle about five times more trash than another of a similar size. They have an enclosed design that prevents scavengers, pests and odours, and are connected wirelessly for easy monitoring and management.
Once the bin is full, its sensors will detect and send, via 3G, email or text message alerts to the mobile phones of cleaners.
Because they work on solar energy, the bins have no cabling. The solar panels power an internal battery that drives the compaction mechanism, internal sensors and the communication module. A fully charged battery can power the bin for about three months without sunlight.
