Missouri homes, businesses and industry produce millions of tons of solid waste every year. Hazardous waste continues to present challenges from both present and past handling practices. The department works continuously to protect public health and the environment by employing current management, permitting, monitoring and enforcement measures. The department also looks for better ways for Missourians to safely and effectively manage the different types of waste they create.
