Hazardous wastes are waste materials that can pose a substantial threat to public health or the environment due to their toxicity, flammability, reactivity, or corrosivity. it can be of any type, solid liquid, or gas.
Characteristics of hazardous waste
The following are the characteristics of hazardous waste
- Ignitability: Wastes that can catch fire easily fall into this category. Examples include gasoline, solvents, and alcohol-based products.
- Reactivity: Reactive wastes are unstable under normal conditions and can cause explosions, toxic fumes, or other hazardous reactions. Think of old explosives or reactive chemicals.
- Toxicity: Toxic wastes are harmful when ingested, inhaled, or absorbed. it includes heavy metals like lead and mercury and certain pesticides.
Differentiating Between Toxic and Hazardous Wastes
| Toxic waste | Hazardous Wastes |
| It contains materials that are poisonous to humans, animals, or plants. | It includes toxic materials as well as ignitable, corrosive, and reactive substances. |
| Toxic waste directly affects biological systems. | Hazardous waste encompasses physical dangers like fires or chemical reactions. |
| Defined by toxicity | Defined by various hazardous properties |
| Example: Mercury, lead-based paints | Example: Industrial solvents, acid baths |
Conclusion
Hazardous waste is a growing global concern that requires collective action. By understanding its characteristics and differentiating between toxic and hazardous wastes, we can make the right decisions about its management. Let’s work together to protect our planet and future generations.
