A modern landfill for household waste

The diagram shows the design of a modern landfill for household waste. Summarize the information by selecting and reporting the main features and make comparisons where relevant.

1. Analyse


  • Man-made garbage pit on the ground with 2 layers

  • In which household waste is kept

  • Hazardous liquids are removed from the landfill by a gas pipeline system.

This question belongs to the 'Process' category. Here are some questions that can help you understand the Process better:

  1. What is the starting and ending point of the process?

  2. Is this process Circular (Acyclic process, with the same starting and ending points) or Linear (Linear process, with separate start and end points)?

  3. How many steps are there in total?

  4. Is this process purely natural or man-made?

  5. Is anything added in the process?

  6. What is the function of each step/phase?

  7. Is there a relationship between the steps/stages?

  8. At the end of the process, what product is produced?

2. Writing Sample

The given diagrams provide an illustration of a modern landfill for household wastes. Overall, a typical landfill is a man-made hole dug on a solid, two-layer base in which household refuse is kept and toxic liquids are removed from the landfill by the use of a system of pipes.

The construction of a landfill commences when a large hole is dug out of a site with natural rock underneath. The bottom of the hole is thereafter covered with a layer of clay and another layer of unspecified synthetic substance. A drainage tank which is a box-shaped compartment dug through the two aforementioned layers and a set of drainage pipes are also installed.

When used, the landfill is filled up with household waste, with the leachate being extracted and eventually flowing out of the site in liners. Once the rubbish has been converted into a mud-like compound, the landfill is sealed with clay, and gases that are emitted as a result of the conversion is eventually pumped out to an unspecified zone.
