Which of the following is NOT one of the four types of hazardous waste?

Inert waste is materials that do not undergo any significant physical, chemical, or biological changes and typically do not pose a risk to the environment or human health. This category is not classified as hazardous waste. The four primary types of hazardous waste generally include flammable, toxic, corrosive, and reactive wastes.

Flammable waste can easily ignite and cause fire hazards, toxic waste contains harmful substances that can pose health risks, and corrosive waste can cause severe damage to materials and organisms. In contrast, inert waste remains stable and does not exhibit the dangerous properties associated with hazardous waste. Understanding these classifications helps in effective waste management and compliance with environmental regulations.
