Waste Management

Choose the Correct Answer

Correct Answer : Option c

Explanation
Correct option (c): Waste To Energy plants help reduce landfill waste by converting non-recyclable waste into energy. However, if not properly managed, they can release toxic emissions like dioxins, furans, and heavy metals, which require strict pollution control measures.

Other incorrect options:

Option (a): Waste-to-Energy (WTE) plants do not process all types of waste; they primarily handle combustible materials like plastics, paper, and organic waste. While modern WTE plants have emission control systems, they still produce some emissions, including carbon dioxide (CO2), dioxins, and other pollutants.

Option (b): Anaerobic digestion is used mainly for organic waste (like food waste and sewage sludge), producing biogas. However, the most common method in WTE plants is incineration, where waste is burned to generate steam, which drives turbines to produce electricity.

Option (d): Waste To Energy plants process both biodegradable (organic) and non-biodegradable waste to generate energy. Organic waste can be used in anaerobic digestion, while non-recyclable waste is incinerated.
