In the context of hazardous-waste management, waste is classified based on biological, chemical, and physical properties that pose risks to human health and the environment. These properties categorize materials into the following types:
- Toxic: Substances that act as poisons, causing acute illness, death, or chronic conditions such as cancer or mutagenic effects.1
- Reactive: Materials that are chemically unstable and prone to violent reactions with air or water, potentially leading to explosions or the release of toxic vapors.1
- Ignitable: Wastes that burn at relatively low temperatures, creating an immediate fire hazard.1
- Corrosive: Strong acidic or alkaline substances that destroy living tissue and solid materials through chemical reaction.1
- Infectious: Materials such as medical waste from hospitals or research facilities that may carry pathogens.1
- Radioactive: Substances that emit ionizing energy capable of harming living organisms.1
Proper management of these materials is an ethical imperative to protect public health and the environment from the dangers posed by their inherent characteristics.12
