What does the term 'hazardous waste' refer to in the context of pesticides?

The term 'hazardous waste' in the context of pesticides refers to any unwanted pesticide that could harm the environment or human health. This definition encompasses a wide range of substances, as pesticides can pose significant risks when not managed properly. Hazardous waste includes pesticides that are expired, unused, or improperly disposed of, as their potential to cause harm to ecosystems and human populations is substantial. This definition underscores the importance of responsible handling and disposal practices to mitigate risks associated with pesticide use.

In this context, empty pesticide containers, while they must be handled carefully to prevent contamination, do not fall under the category of hazardous waste unless they have residues that could be harmful. Pesticides that no longer meet safety standards could potentially be considered hazardous, but the broader definition focuses on any unwanted pesticide. Additionally, pesticides found only in industrial settings do not represent the comprehensive scope of hazardous waste, as hazardous pesticides can exist in residential or agricultural settings as well.
