Question 1:

Which of the following is NOT a waste disposal method?

Explanation: Recycling is not a waste disposal method but a waste management practice that involves converting waste materials into new products. It aims to reduce waste generation and conserve resources by reusing materials. The other options—incineration, landfilling, and composting—are waste disposal methods commonly used for different types of waste.

Question 2:

What is landfilling?

Explanation: Landfilling is the waste disposal method that involves burying waste in designated areas called landfills. It is one of the most common methods used for the disposal of municipal solid waste (MSW). Landfills are carefully engineered to minimize environmental impacts and prevent the release of harmful substances into the surrounding environment.

Question 3:

What is incineration?

Explanation: Incineration is the waste disposal method that involves the combustion of waste materials at high temperatures. It is a process that can reduce the volume of waste and generate energy in the form of heat or electricity. Incineration is commonly used for the disposal of certain types of waste, such as medical waste or hazardous waste.

Question 4:

What is composting?

Explanation: Composting is the waste disposal method that involves the breakdown of organic waste materials by microorganisms under controlled conditions. It is a natural process of decomposition that produces compost, a nutrient-rich soil amendment. Composting is commonly used for the recycling and beneficial reuse of food scraps, yard waste, and other biodegradable materials.

Question 5:

What is sanitary landfilling?

Explanation: Sanitary landfilling is the waste disposal method that involves the burial of waste with minimal environmental impact. Unlike traditional landfills, sanitary landfills are engineered with protective measures to prevent environmental contamination, such as liners, leachate collection systems, and gas management systems. These measures help minimize the release of pollutants into the soil, water, and air.
