Which of the following is considered hazardous waste?

Hazardous waste is defined as waste that poses substantial or potential threats to public health or the environment. In this context, solvents are classified as hazardous waste because they often contain toxic chemicals that can be harmful if not managed properly. Many solvents used in cleaning, painting, and other industrial applications may release harmful vapors, are flammable, or can contaminate soil and water, making them a significant environmental risk.

In contrast, food scraps are generally considered organic waste, which can be composted and do not pose the same level of immediate hazard. Non-toxic household materials typically lack harmful components and can usually be disposed of without requiring special handling. Similarly, paper products are recyclable and not classified as hazardous. Therefore, solvents stand out as a prime example of hazardous waste due to their potential dangers.
