Somerville, MA – In the ongoing struggle against climate change, enter the texting trash can.
This month, Somerville, Mass., will install text-messaging technology in about 50 public trash cans located in high-pedestrian and far-flung areas. The idea is that the cans, made by BigBelly Solar, will transmit text messages to a central database, notifying haulers that they are full and allowing town managers to maximize collection efficiency.
Somerville has about 50 BigBelly cans - a handful purchased in early 2007 and the rest last April. Like the robotic trash collector popularized in Pixar’s film “Wall-E,” BigBelly units compact trash as it is deposited, and obtain the energy to do so from the sun — via a photovoltaic panel on top.
BigBelly says its smart cans … holds 180 gallons of trash, compared to 30 gallons for a normal can. And by compacting trash themselves, they can reduce garbage collection trips by 80 percent.
Somerville will now be the first to add the text-messaging feature.
Michael Lambert, the chief of staff to Somerville’s mayor, Joseph Curtatone, says the technology will allow the barrel to radio a signal to city hall, alerting a customer service representative that it’s full.
“So we don’t have to check it anymore,” Mr. Lambert said. “We just have to go whenever needed.”
Whatever savings are derived from the move will come atop those already expected from the BigBelly units. The city decided last year to “saturate” its most highly trafficked area, Davis Square, near Tufts University, with six BigBellys.
“We had been visiting that area three times a day to empty the traditional bins, and now we go there twice a week,” Mr. Lambert said. The city has saved on gas, vehicle maintenance and labor costs, he reported, and the cans have helped reduce traffic in an already congested area.
From just the six cans at Davis Square, Mr. Lambert said, the city expects savings of $14,000 annually.
Estimates vary, but one oft-quoted statistic puts the number of garbage trucks in the United States at over 130,000, collectively burning over 1 billion gallons of diesel fuel each year. Reducing the number of trips they make could provide significant fuel savings, as well as reduce emissions.
