An apparatus to prevent workers from inadvertently discarding metal
articles is used in the hospitality industry. The apparatus includes a
base suitable for mounting to an open end of a waste receptacle, a tray
pivotally mounted to the base, and a metal detector mounted to the
underside of the tray. The metal detector detects the presence of metal
articles deposited in the tray amidst food scraps or other waste. The
metal detector signals an audible alarm alerting workers to the presence
of metal articles in the waste. Once the metal articles are removed, the
worker can use a handle or a button system to pivot the tray, so as to
deposit the food scraps or other waste in the waste receptacle.
