Hazardous waste refers to ignitable, reactive, corrosive, or toxic substances that require careful handling to prevent harm to human health or the environment. Annual global production ranges between 300-500 million metric tons, with examples including batteries, electronics, and chemicals. Regulatory frameworks, such as the U.S.
Resource Conservation and Recovery Act and Singapore’s Hazardous Waste Act, emphasize environmentally sound management, cross-border controls, and reduced generation. The Philippines’ Ecological Solid Waste Management Act defines hazardous waste and mandates appropriate disposal. These approaches collectively highlight the importance of legal, international, and local strategies to minimize the risks associated with hazardous waste.
