Due to the acknowledged dangers of cigarette smoke and in particular second hand smoke, many buildings are now designated as non-smoking buildings where smokers are not allowed to have or bring lit cigarettes inside. Often a designated outdoor smoking area is provided where employees or others may congregate to partake of a smoking break during the day. Because of these policies, it is not uncommon to find a cigarette butt disposal problem at building entrances and designated smoking areas, in that many individuals will simply drop their cigarette butts or partially smoked cigarettes on the ground, resulting in unsightly collections of large numbers of cigarette butts. Since the butts do not degrade, the areas must be cleaned often.
A common response to this situation has been to place ashtray-type trash collector devices in the needed locations. These ashtray-type devices consist of an upright cylindrical tube with a concave retainer of exposed sand on the top. Apertures for insertion of trash are placed on the side of the cylinder.
