How is contaminated waste classified?

Contaminated waste is classified based on its origin, toxicity, and potential environmental impact because these factors play a critical role in determining how it should be handled, treated, and disposed of. The origin of the waste (e.g., industrial, municipal, or agricultural) helps identify the types of hazardous materials present and informs the regulatory requirements for its management. Toxicity assesses the harmful effects the waste can have on human health and the environment, which is crucial for establishing safe handling practices and protective measures.

Furthermore, understanding the potential environmental impact is essential for implementing appropriate containment, treatment, and disposal methods to prevent pollution or harm to ecosystems. This classification approach aligns with regulatory frameworks, such as the Resource Conservation and Recovery Act (RCRA) in the United States, which mandates careful consideration of these factors when managing hazardous waste.
