SWANA gave Hamm Waste Services the 2017 Sustanable Materials Management Best Safety Innovation award for 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.
