An apparatus for opening garbage bags in a municipal waste processing stream including a drum rotatable above the stream of municipal waste with a plurality of discrete tearing elements extending outwardly from the drum into the stream of waste, to tear through bags while yielding to more resistant articles in the stream of waste. The drum is suspended from arms pivotally mounted above the drum, so that the drum will yield to large items in the waste stream.
