Question

The safe method of disposal of e-waste is
A. Incineration
B. Burning in open field
C. Thrown into water
D. Dumping in forest

Answer 1

Hint:-: Waste disposal is the method that is employed to destroy or recycle unused, old, or unwanted domestic, agricultural, medical, or industrial waste. Electronic goods such as computers comprise the E-wastes or electronic wastes. Generally metals such as copper, iron, silicon, gold make a large proportion of e-waste. Hence, these wastes are highly toxic and cause serious health hazards.

Complete step-by-step solution:-
- The e-waste refers to the electronic waste which is increasing in the amount every day.
- The need of the hour is to dispose of the e-waste safely and properly. Thus, the process of incineration is considered as a safe method for the disposal of this form of waste.
- The process of Incineration involves the process of controlled combustion of garbage to reduce it to incombustible matter such as ash and waste gas.
- This involves the burning of the waste at very high temperatures in a furnace.
- The process of incineration is considered as one of the most hygienic methods of waste disposal because it reduces the volume of waste by 90 percent and is.
- Sometimes the heat generated in this method is used to produce electricity.
- Although incineration is a non-eco-friendly process as exhaust gases from this process may be toxic, hence it is treated before being released into the environment, but it is one of the safest ways of disposal of hazardous wastes like e-waste.
- The e-wastes can’t be burnt in fields as it will create huge air pollution.
- E-wastes can’t be thrown in water as it might cause large scale water pollution, affecting the animals in the water, or can cause eutrophication.
- It can’t be dumped in forests as the toxic metals can produce harmful radiations which can affect the forest and mankind.
Hence, the correct answer is option A, Incineration.

Note:- Solid waste is typically disposed of by the process of incineration – where the waste materials are heated to very high temperatures and reduced to ash, flue gas, and heat. There are many methods of waste disposal including; landfill, incineration, waste compaction, composting, and vermicomposting.
