Waste that potentially and substantially threatens all forms of life on earth is termed hazardous waste. • Hazardous waste is of different types and has several characteristics. • You can find dangerous wastes in all three physical states - solid, liquid, and gas.
Characteristics of hazardous waste • Hazardous waste generally exhibits one or more than one of the following characteristics: Ignitability • Ignitable hazardous wastes can be of three types : • Liquid hazardous waste having a flashpoint. Flashpoint is the lowest temperature at which fumes which are above the waste material start igniting. Some examples of such liquid waste are acetone, alcohol, etc. • Combustible Solids • Compressed gases and oxidizers
Corrosivity It means that the waste can easily rust or decompose. Corrosive substances are capable of destroying other materials. • Reactivity Some hazardous waste materials are highly reactive. Such reactive wastes are dangerous and can even cause an explosion. • Toxicity Waste materials can also be toxic. Toxic waste poses severe threats to human health and the environment.
Disposal of Hazardous waste People need to manage hazardous waste. There are several ways to dispose of such waste. The best way to keep dangerous waste materials under control is by reducing the production of hazardous waste or by recycling this waste for some productive use. However, reducing and recycling hazardous waste materials are not the final remedies to get rid of this waste. These waste materials need to be treated for storage purposes, while some waste materials need disposal.
Physical, chemical, Biological Treatment of waste • Youcan make use of thermal, chemical, biological, and physical methods to treat hazardous waste. • Incineration is a thermal method used to treat hazardous waste. • This method is used to detoxify most hazardous waste and can even destroy some waste materials.
You can also use the process of incineration to burn solid waste, liquid waste, or waste in the form of sludge. • Multiple-hearth furnace, fluidized-bed or liquid-injection incinerator, and rotary kiln are disposal instruments. • You can also treat hazardous waste materials biologically. • One effective way to treat such waste materials biologically is by landfarming.
Landfills • The residual waste from incineration or the trash that cannot be recycled or treated thermally is deposited in landfills. • Such landfills must comply with the legal requirements. If the waste does not satisfy the legal conditions for landfilling, it needs to be pre-treated. • The waste that complies with the requirements can be deposited in landfills.
In this process, the manure is spread as a thin layer in a low-lying area. • The addition of a layer of soil is done after each layer of waste. • This region is considered unfit for construction purposes for the next few years. • However, the area can be used as a park or a playground.
Conclusion Some companies provide hazardous waste collection and disposal services to ensure a safe environment. Such services also includechemical container disposal, metal disposal, or customized services per the requirement of companies or individuals. It is feasible to make the most of these services for the environment's welfare and humanity.
