What does the term "hazardous waste" refer to?

The term "hazardous waste" refers to waste that poses substantial or potential threats to public health or the environment. This definition encompasses a wide range of materials that can be harmful if not managed appropriately. Hazardous waste is typically characterized by its quantity, concentration, or physical, chemical, or infectious nature that may be dangerous or pose risks when disposed of improperly. This can include materials that are toxic, flammable, corrosive, or reactive.

While some refuse can be recycled, that does not define hazardous waste, as hazardous waste specifically refers to materials that can harm individuals or the environment rather than recycling capabilities. The idea of non-hazardous materials requiring special disposal relates to specific waste management practices, but these materials do not meet the criteria for hazardous waste. Waste generated from household cleaning activities can also often be non-hazardous and does not necessarily signify that all such waste is hazardous. Only certain substances from household cleaning may fall into the hazardous category, depending on their chemical composition and effects. Therefore, the correct understanding aligns strictly with the definition that recognizes significant threats to health and environment as outlined in the correct response.
