These interesting looking solar powered bins have recently gone on trial in Inverness. The bins which have been called the “Big Belly” can take eight times as much rubbish as a normal bin of the same size. Machinery inside the bin compacts the litter automatically and an internal computer is programmed to send an email to the council when the bin is full and needs to be emptied. The bins are solar powered and need only eight hours of daylight a day to power the electronic device inside. At £3,200 they are not cheap but perhaps the cost will work itself out if they don’t need to be emptied so often.
