- Eco-Friendly Chip Seal and Masonry with Recycled Crumb Rubber Studies
-
The Missouri University of Science and Technology received a grant from the department to test whether or not crumb rubber from scrap tires could be used as a replacement for mineral aggregate in chip seal and concrete masonry units. During the masonry tests, crumb rubber particles were used as a partial replacement of natural mineral aggregate to produce rubberized concrete masonry units. Rubber fiber powder was also used as a sand replacement in mortar for plastering masonry. Test results showed that crumb rubber can be used as a partial replacement for both uses. The crumb rubber protected against corrosion and improved sound absorption and noise cancellation.
Chip seals are one of the most cost and performance effective pavement preservation treatments commonly used in the United States. During the tests, the crumb rubber chip seal was compared to two different types of conventional chip seals. The chip seals were tested under simulated traffic load with different load parameters and environmental conditions. The tests results showed that scrap tires can be used as a partial or full replacement with many positive outcomes. The tire chip seal performed well with increased adhesion to asphalt and showed no negative impact to the environment. Not only could millions of tons of scrap tires be diverted from landfills, but this new chip seal will help reduce noise from high traffic areas and enhance roadway safety.
- Hazardous Waste Permit Modifications List
-
Missouri laws and regulations require the department to maintain a list of all approved hazardous waste permit modifications for the previous calendar year. The department makes these lists available to the public for review. The reports for the two most recent years are provided below. If you would like a list from a different year, contact the Waste Management Program.
- Registry of Abandoned or Uncontrolled Hazardous Waste Sites
-
The Registry of Abandoned or Uncontrolled Hazardous Waste Sites, also known as the Registry, is a list of sites in Missouri that are contaminated with hazardous waste.
- Missouri Solid Waste Management Plan
-
One responsibility of the department's Waste Management Program is to ensure solid waste is managed in a way that protects both public health and the environment. Since waste is an issue that affects all Missourians, the department invited private citizens, businesses and industries and state and local governments to help develop a comprehensive plan for managing solid waste through the year 2030. The Missouri Solid Waste Management Plan below represents a number of objectives and strategies, which were proposed to help all Missourians manage waste as a resource and use disposal methods that protect human health and the environment.
- Solid Waste Advisory Board Annual Report
-
The Solid Waste Advisory Board advises the Waste Management Program on various solid waste management issues. Missouri laws and regulations require the board to submit an annual report to the department and committees in the General Assembly having jurisdiction over solid waste. The Solid Waste Advisory Board Annual Report discusses several topics, such as the effectiveness of its technical assistance program, solid waste management problems experienced by Missouri's solid waste management districts and unfunded solid waste management projects. This report is issued on or before January 1.
- Solid Waste Management Program State Audit
-
In September 2013, the Missouri State Auditor conducted an audit of the department’s Solid Waste Management Program, now the Waste Management Program. The audit included a review of the program's procedures for monitoring the expenditure of funds that the department provides to Missouri's 20 solid waste management districts and other subgrantees. The solid waste management districts assist the department in carrying out the Missouri Solid Waste Management Plan. The results of this audit are provided in the Solid Waste Management Program Audit, Report No. 2013-092.
- Waste Composition (Characterization) Studies
-
The state of Missouri has conducted numerous waste composition studies, with the most recent being completed in 2017. These studies categorize waste going into Missouri's landfills or received at Missouri's transfer stations. This information gives the department a clear picture of what is being disposed in our landfills and, more importantly, what items could have been recycled, reused or composted. The department's Waste Management Program uses this information to provide technical expertise to Missouri's solid waste management districts. The districts are then able to work more effectively with their communities to decrease the amount of waste being disposed in our landfills.
