Hazardous Waste (Non-Residential)
Hazardous waste is any waste, or combination of wastes, as determined by rule or regulation of the Missouri Hazardous Waste Commission, which because of its quantity, concentration, or physical, chemical or infectious characteristics, may cause or significantly contribute to an increase in mortality or an increase in serious irreversible, or incapacitating reversible, illness, or pose a present or potential threat to the health of humans or the environment.
The state of Missouri has imposed a landfill ban on regulated hazardous waste. If you are a generator of hazardous please, please contact Missouri Department of Natural Resources for a list of facilities licensed to accept such waste.
All hazardous waste must be prominently labeled “HAZARDOUS WASTE” and stored in accordance with applicable state and federal regulations.
Infectious and Biohazard Waste
These wastes contain pathogens of sufficient virulence and quantity that exposure to these wastes by a susceptible human host could result in infection. Examples of these wastes include wastes generated from patients with communicable diseases, cultures and stocks of etiologic agents, surgery and autopsy wastes, sharps and contaminated laboratory wastes.
Residential: According to the Saint Louis County Waste Code Section 607.897, residents can dispose of sharps in their regular trash. To protect sanitation workers, they must be packaged in rigid, leak-proof and puncture resistant containers (detergent bottle, for example), which are sealed prior to disposal.
Non-Residential: All infectious waste must be stored in a sealed, leakproof container prominently marked “INFECTIOUS WASTE” or “BIOHAZARDOUS WASTE.” Discarded sharps must be placed in containers which are also rigid and puncture-resistant. All containers must be clearly marked with the universal biohazard symbol. All wastes should be stored in a manner that does not pose significant hazard or nuisance in the workplace, to the public, or to the environment ( Waste Management Code 607.090).
Recovered Materials (Recycling)
These are materials that have been diverted or removed from the solid waste stream for sale, reuse or recycling, whether or not they require subsequent separation and processing. This does not include yard by-products.
In Saint Louis County, most residents have single stream curbside recycling that accepts most household recyclables. Many recovered materials see new life through innovative thinking and technological advancements. Additional recyclables include consumer electronics, tires, vehicle batteries, plastic grocery bags, clothes, and appliances. For more information please visit our Recycling Information page.
Recovered materials must be stored in a neat, clean, odor-free and sanitary manner and stored at the same property in which they were generated. Containers for collection and storage of recyclables must conform to the requirements of your service provider.
Recycling collection in Saint Louis County is handled by private haulers or municipalities. Some municipalities may use a back door recycling service while many other municipalities and subdivisions use the curbside collection method. Check with your hauler to find out their requirements.
