Boston is solving the problem of overstuffed public trash cans with solar-powered, self-compacting replacements:
They are Menino's latest idea for keeping the city litter-free: solar-powered, self-compacting trash receptacles. Delivering a rant about overstuffed trash cans, while trying to scrape gum off the bottom of his shoe at a Downtown Crossing unveiling, Menino described the virtues of the new devices. They need emptying only once or twice a day, not the 15 or more sanitation worker visits required by some downtown trash cans. They don't spill. They smell less. And, they hold some 150 gallons of trash, about five times more than a standard city receptacle.
