Which of the following is included in hazardous waste?

Biological substances are considered hazardous waste because they can pose significant health risks to humans and the environment. These substances include pathogens, medical waste, and other materials that can carry infectious agents. Proper handling and disposal of biological waste are regulated to prevent contamination and the spread of diseases.

In contrast, organic materials, while they may decompose and create environmental concerns if not managed, are not inherently hazardous waste. Non-toxic chemicals do not qualify as hazardous waste as they do not pose a risk to health or the environment. Household waste typically contains a mix of materials, including recyclables and non-hazardous items, and is generally not classified as hazardous unless it contains specific dangerous components.

Thus, biological substances are recognized for their potential hazards, necessitating strict guidelines for their management, making them a fitting example of hazardous waste.
