Officials and environmentalists will gather in Maine’s largest city to unveil Portland’s latest effort to eliminate cigarette butt litter.

A city spokeswoman says about five dozen “Sidewalk Buttler” cigarette dispensers were recently installed around the city. The tubular receptacles resemble mustachioed butlers and have mouth-shaped inserts where smokers can dispose of cigarette butts.

City officials, business owners and a representative from the Natural Resources Council of Maine will gather in Portland City Hall at 11 a.m. on Wednesday to demonstrate how the buttlers work. The council says the buttlers are “a sensible, easy way Portland is tackling cigarette butt litter.”
