FAQs on What is a Landfill? Video Lecture - Basic Science for Primary 5

1. What is a landfill?

Ans. A landfill is a designated area where waste materials are disposed of by burying them in the ground. It is a common method of waste management used to handle and control the accumulation of solid waste.

2. How does a landfill work?

Ans. Landfills are engineered sites designed to safely isolate and contain waste. Layers of waste are compacted and covered with soil daily to minimize odor, prevent contamination, and discourage pests. Over time, the waste decomposes and settles, ultimately forming a stable foundation.

3. What types of waste are typically found in landfills?

Ans. Landfills accept various types of waste, including household garbage, construction debris, industrial waste, and non-hazardous materials. However, hazardous waste, such as chemicals or flammable materials, are strictly regulated and not permitted in landfills.

4. Are landfills harmful to the environment?

Ans. Landfills, if not properly managed, can pose environmental risks. The decomposition process produces methane, a potent greenhouse gas, and the potential for groundwater contamination exists. However, modern landfills implement advanced technologies and safety measures to minimize these impacts.

5. How long does it take for waste to decompose in a landfill?

Ans. The decomposition time of waste in a landfill varies depending on various factors such as the type of waste, climate, and landfill management practices. Organic materials like food waste can take several months to years to decompose, while certain plastics can take hundreds of years to break down completely.
