A new generation of “smart bins” is being introduced which promises an end to litter-strewn public spaces and aggressive seagulls by emailing collectors as they become full.The solar-powered receptacles are roughly the same size as normal bins but can accommodate around ten times the volume thanks to a crushing system which compacts the waste.This, combined with a modem which allows councils to accurately monitor rubbish levels, is reducing the number of bin collections in parks and on busy pavements by up to 90 per cent.The units, which are currently being trialled in five local authority areas in England, have been welcomed by environmental and anti-litter campaigners for tackling both the problem of unsightly overflowing public bins, as well as the wasted costs and emissions involved in routinely emptying bins that are not yet full.–– ADVERTISEMENT ––In two busy neighbourhoods of Waltham Forest in East London, council waste collectors were able to reduce their visits from three times a day to three times a week.The bins are also designed to deter scavenging birds and vermin because they are sealed except when opened using a foot pedal.The manufacturers, Irish firm PEL, say their Solar Street Bin can last 13 weeks without a light source.

They comprise a relatively early utilisation of the so-called “internet of things” – where physical objects can be controlled or monitored via the web – for public spaces, and follow similar trials by a different manufacturer in Nottingham and the City of London.Samantha Harding, Litter Programme Director at the Campaign to Protect Rural England, said: “These bins are a good way for councils with ever-shrinking budgets to deal with the ever-growing amount of waste.”In addition to Waltham Forest, trials of the solar bin are currently underway in Greenwich and Haringey in London, as well as Fareham in Hampshire, East Devon and Glasgow.The bins each cost £95 a week to rent, or around £4,000 to purchase.An inbuilt thermometer is also linked to the modem so councils can monitor the temperature in the bin and order early collections in particularly hot whether. The also include USB ports so passers-by can charge their phones in emergencies.Greenwich council has said that no workers will be made redundant by the new technology, but instead will be redirected to other street-cleaning tasks. San Francisco, Paris, Oslo and Dubai are among some of the overseas cities embracing the technology.
