LONDON: World’s most technologically advanced bin has gone on trial, with a London council believing that despite its hefty price tag, it could save them money.

The BigBelly Solar bin harvests energy from the sun and uses it to compact waste to an eight of its size.

The cost of leasing the high-tech bin is an eye-watering £1,000 a year when leased for five years but because of its huge capacity, it could save councils money in vehicle journeys and fuel to collect waste.

The solar-powered unit runs on a 12v battery.

It needs just eight hours of sunlight per month to function as intended and is currently on trial in Merton, south west London.–DM
