A project to collect discarded cigarette butts from downtown city streets has reached the two-year mark and it has been a big success. Downtown Grand Rapids Inc., the group that helps manage what goes on downtown, installed 20 cigarette butt recycling urns about two years ago. Nicole Hills and Veronica Kuhl assumed they were doing what everyone should do when they used one of several urns located on Monroe Center Street.“Don't be an ugly American, clean up after yourself,” Kuhl said. “I don't throw trash out my car. You know, clean up after yourself.” Butts are collected from the urns every day, bagged up and sent to TerraCycle, a New Jersey firm that collects and then separates the butts.
