Which of the following can be disposed of in a sanitary landfill?

The disposal of pesticide waste in a sanitary landfill is subject to strict regulations due to environmental and health concerns. Only non-hazardous pesticide wastes can be disposed of in a sanitary landfill because these types of waste do not pose a threat to public safety or environmental contamination. Non-hazardous waste typically includes materials that do not exhibit hazardous characteristics such as ignitability, reactivity, or toxicity.

For hazardous pesticide wastes, disposal is often restricted to specialized facilities designed to handle those materials safely. Liquid pesticide mixtures are generally not permitted in landfills due to the potential for leaching and contamination. Moreover, pesticide containers, depending on their state (used, unused, or rinse) and contents, also have specific disposal requirements, and not all can be disposed of in regular landfills.

By recognizing only non-hazardous pesticide wastes as suitable for sanitary landfills, it ensures that pesticide disposal aligns with environmental safety standards and protects both human health and the ecosystem.
