Which type of waste must adhere to strict disposal regulations due to potential hazards?

Hazardous waste must adhere to strict disposal regulations because it poses significant risks to human health and the environment. This type of waste can contain harmful substances that are ignitable, corrosive, reactive, or toxic, and its improper management can lead to contamination of soil, water, and air. Consequently, federal and state regulations, such as those established by the Resource Conservation and Recovery Act (RCRA), govern the handling, transportation, treatment, and disposal of hazardous waste to ensure safety and compliance.

In contrast, residential solid waste, green waste, and recyclable materials typically do not contain the same level of hazardous substances and therefore are subject to less stringent disposal regulations. While they still require appropriate management to minimize environmental impact, they do not present the same immediate threats as hazardous waste.
