Heavy machinery moving solid waste at the Backridge Landfill

Missouri solid waste disposal areas and solid waste processing facilities designated by rule, must be operated under the direction of a certified solid waste technician. The department administers the certification program and provides classes and other opportunities to help you stay up-to-date on your certification. 

Certification Class

Registration is now open for the spring Solid Waste Technician Certification Course. The course will take place Dec. 14, 2021, between 8 a.m. - 5 p.m. Individuals obtaining a new certification must also complete a certification test at 9 a.m. Dec. 15, 2021. This is an online, remote course, and a strong internet connection is required. The agenda, course materials and virtual course link (and instructions) will be posted on this webpage. This course will satisfy recertification hours for individuals with a non-expired certification.

Please note the Waste Management Program is reducing the frequency of the Solid Waste Technician Certification Course to once per year. The next course will be in December of 2022. If your certification expires between now and December. 2022 and you do not have additional training planned that can be used for recertification, it is recommended that you attend the Dec. 14, 2021, Solid Waste Technician Certification Course to prevent your certification from expiring.

The fee for this course is waived. For more information or questions, contact the Waste Management Program at l.wylie@dnr.mo.gov or 573-526-3624
