Sanitary Landfilling Concepts Assessment

The video tutorial explains sanitary landfilling, a common waste disposal method. It covers the stages of landfilling, including site selection, preparation, waste placement, daily cover, gas collection, leachate treatment, and final closure. The benefits and drawbacks of landfilling are discussed, highlighting its cost-effectiveness and environmental impact. The video emphasizes the importance of reducing waste generation through prevention, reuse, and recycling to minimize environmental impact.

What is the primary consideration when selecting a site for sanitary landfilling?

• Suitable soil and groundwater conditions

• Presence of wildlife

• Proximity to residential areas

• Availability of water bodies

What is the purpose of installing a liner system during site preparation?

• To enhance the aesthetic appeal

• To prevent leachate from contaminating groundwater

• To attract wildlife

• To increase the landfill's capacity

How is waste managed in a landfill to ensure stability?

• By mixing it with water

• By spreading it randomly

• By compacting it in layers

• By burning it

What is the role of daily cover in landfilling?

• To prevent odors and pests

• To beautify the landfill

• To increase waste decomposition

• To attract birds

What happens to landfill gas produced during waste decomposition?

• It is stored underground

• It is collected and used to generate electricity

• It is used to attract wildlife

• It is released into the atmosphere

What is the purpose of the final closure of a landfill?

• To prevent the release of landfill gas and leachate

• To attract tourists

• To allow for future waste disposal

• To convert it into a recreational area

Which of the following is a benefit of sanitary landfilling?

• It requires no maintenance

• It is the fastest method of waste decomposition

• It can dispose of a wide variety of waste materials

• It is the most expensive method of waste disposal

What is a major environmental concern associated with sanitary landfilling?

• It enhances biodiversity

• It reduces greenhouse gas emissions

• It can lead to pollution of air, water, and soil

• It improves air quality

Why is sanitary landfilling not considered a sustainable solution?

• It is too fast

• It does not reduce waste generation

• It is too cheap

• It is too complex

What is the best way to minimize the environmental impact of waste disposal?

• By increasing landfill size

• By reducing waste generation

• By burning all waste

• By exporting waste to other countries
