Question 1:

What is Waste-to-Energy (WtE) technology?

Explanation: Waste-to-Energy (WtE) technology is a technology that converts waste into usable energy, typically in the form of electricity, heat, or fuel. It involves various processes such as incineration, gasification, and anaerobic digestion to extract energy from waste materials while minimizing their environmental impact.

Question 2:

Which of the following is a benefit of Waste-to-Energy technologies?

Explanation: One of the benefits of Waste-to-Energy technologies is the reduction in landfill usage. By converting waste into energy, less waste needs to be disposed of in landfills, reducing the need for additional landfill space. This helps mitigate environmental and health risks associated with landfills, such as groundwater contamination and methane emissions.

Question 3:

Which waste material is commonly used in Waste-to-Energy technologies?

Explanation: Biodegradable waste is commonly used in Waste-to-Energy technologies. This includes organic waste such as food waste, agricultural residues, and sewage sludge. These waste materials contain organic matter that can be efficiently converted into energy through processes like anaerobic digestion or composting.

Question 4:

What is the primary energy output of Waste-to-Energy technologies?

Explanation: The primary energy output of Waste-to-Energy technologies is electricity, heat, or fuel. These technologies convert waste materials into usable energy forms that can be utilized to generate electricity, provide heat for industrial processes or district heating, or produce fuel for vehicles or other applications.

Question 5:

What are some environmental considerations associated with Waste-to-Energy technologies?

Explanation: One environmental consideration associated with Waste-to-Energy technologies is the potential for increased greenhouse gas emissions. While these technologies can help reduce overall waste volume and dependence on fossil fuels, certain processes, such as incineration, may release greenhouse gases and other pollutants into the atmosphere. Proper emission control measures are necessary to mitigate these environmental impacts.
