Region M aims to reduce solid waste in landfills through source reduction, recycling and programs designed to educate the public about the importance thereof.

In 1990, to facilitate regional planning for solid waste management, the Missouri General Assembly passed SB530. This law provided guidelines for the formation & operation of 20 solid waste management districts within the state. The REGION M-SWMD was formed pursuant to RSMo., Section 260.305, and is officially recognized by the Missouri Department of Natural Resources (MDNR).

The REGION M Waste Management District includes the counties of Barton, Jasper, Newton, McDonald, Vernon, and their participating cities. Participation is voluntary and is formally established through a resolution of adoption filed with the district office by the member governments.
