Hamm Waste Services earned the 2017 SWANA Safety Award Overall Winner for their MRF 5S system. As part of its movement towards lean processes and increased safety, Hamm Waste Services begun the process of 5S implementation at their material recovery facility (MRF) in Lawrence, KS. The MRF 5S system improves housekeeping and organization; reduces employee exposure to rolling stock; and further intensifies employee focus on safety, operational process, and risk minimization. This innovation reduced occupational hazards and exposure in the facility by over 50%.
