Finnish firm Enevo, which developed a sensor-based system for monitoring the fullness of bins, said that a pilot project in Nottingham has reduced litter bin collections by 70%.
Nottingham, where Enevo opened a UK office this year, previously used a standard daily collection route to empty the city’s litter bins, with almost all of them being emptied regardless of how full they were.
Since putting in place the Enevo ONe system, litter bins are now only emptied on demand, with sensors retrofitted into standard street bins.
Olli Gunst, Enevo marketing manager, said: “This is one factor that makes us interesting from the council’s perspective: we can bring smart sensing and optimisation to almost any kind of bin, without them having to invest in new bins.”
Enevo ONe measures how full litter bins are using smart sensors, creates waste forecasts that explain when and where collections are needed, reduces weekend collections, generates efficient collection plans and routes, keeps track of collections, alerts when bins are full, on fire, moved or tipped over, and produces detailed collection reports and statistics.
In 2011, the company rolled out its first pilot measuring and scheduling service to Itä-Uudenmaan Jätehuolto (IUJ) in Finland. IUJ used the service to cut costs and improve the service level of its regional waste collection service.
During the year-long pilot project, IUJ saved around 25% in collection costs and during the winter months it saved 40%. According to Enevo, the cost of the sensors was covered when the system saved IUJ one unnecessary collection per month per container. The ONe Collect system is now part of its daily operations and it has a three-year contract with Enevo.
In 2011 the company further developed its service with a Smart Plans feature, which adds routing to the service. This uses wireless sensors to measure and forecast the fill-level of waste containers and then generates smart collection plans using the most efficient schedules and routes.
While Enevo says its customers are mainly local authorities, it also includes private waste collection and recycling companies.
