The waste receptacle includes a sweeping ramp having protruding teeth. Users may sweep waste up the sweeping ramp, and the teeth serve to hinder the escape of waste from the ramp as the broom head is withdrawn across the ramp surface. A waste bin may be included adjacent the top of the sweeping ramp to receive waste swept up the ramp. A chute may be provided above the waste bin so that users may drop waste down the chute and into the waste bin.
