The city has decided that the five solar-powered compacting trash receptacles you may have seen around were not worth their $4,000 price tag. The cans can hold five times the amount of trash as non-compacting cans and reduce the need for pick-up. (Regular trash cans that you see on street corners cost more than you might think, around $600 or $700.) Although the trash cans have met huge success in larger cities like Philadelphia, Little Rock Recycling Coordinator Melinda Glasgow says they’re probably better suited for parks. “They keep critters out and trash doesn’t blow everywhere and make a mess,” she says. “Maybe the Parks Department would be interested in using them.”
