The City of Kingston is installing 20 receptacles designed to collect cigarette butts so they can be recycled.   "We are working to keep the downtown and transit hubs clean. This is about encouraging people to dispose of cigarette butts in a tidy and environmentally friendly way," says Troy Stubinski, manager, public works operations.   The City and Downtown Kingston! have partnered on a number of efforts to keep the downtown tidy as part of the "Keep it Clean" initiative.   The TerraCycle cigarette disposal receptacles will be placed at transit hubs and certain Express Route stops and gathering places in the downtown.  Once collected, the remaining tobacco will be composted and the butts will be recycled into a variety of industrial products, such as plastic pallets.   Find out more about TerraCycle's cigarette waste recycling program.
