First came trash cans. Then recycling bins. Now robotic trash compactors have joined the clean-up lineup on campus.

Made by a company called BigBelly Solar, the computerized bins are powered by their own solar panels. When sensors feel BigBelly's belly filling up, the compactor turns itself on and goes to work on the trash. When the belly is full, the machine calls for a pickup.

Brown purchased its first Big- Belly last spring—each runs about $5,000—and they've been such a hit that administrators are considering buying more.

"We estimated that each unit saves about twenty-four hours of labor in a one-year period," says Ginger Gritzo, who coordinates energy and environmental programs for the facilities management office. Crews who would normally be emptying trash cans use their new "found" time clearing snow, supporting outdoor events, and generally making the campus look better, Gritzo adds. The compactors also help cut fuel usage and emissions from the vehicles used to lug trash away.

The smart compactors can make the rest of us look kind of stupid. Because the machines lock their doors while they're compacting, some pedestrians have been piling trash on top of them. That prevents solar rays from reaching the photovoltaic panels and so causes the BigBellys to get heartburn from all that undigested trash.

Making people look stupid is a sad outcome for a new & efficient device! Can we not give it a "shoulder bag" to contain debris when it is compacting? Someone will come along and feed the compactor from the bag when it is calm! Maybe the shoulder bag should have an invitation on it suggesting the passerby dump it into the device if it is quiet. Come on! We still have not mastered the ins-and-outs of every food/drink dispenser! We ask for help. Give us stupids a way to cooperate without shutting the device down! I'm impressed that it has proved itself valuable in RI. Haven't seen it in VA!
