Final answer:
Hazardous waste and special controlled products are not fully exempt from regulations due to the potential risks they pose; special regulations govern their disposal and management.
Step-by-step explanation:
Hazardous waste and special controlled products are not fully exempted materials. These are materials that require special handling, labeling, and disposal procedures due to the potential risks they pose to health and the environment. Regulations such as the Resource Conservation and Recovery Act (RCRA) in the United States set the framework for the proper management of hazardous waste. Special controlled products can include materials like industrial chemicals, medical waste, and certain electronic components, which might be toxic, flammable, corrosive, or reactive.
