The diagram below shows how a landfill household waste is designed. Summerize the information by selecting and reporting the main features

The diagram illustrates some steps to create a modern landfill for household waste.

Overall, it is obvious that to design a modern landfill for household waste, there are three main steps, including: construction, usage, and closure.

Regarding construction, people dig a huge hole in the natural rock in order to possibly capacity of household waste.

Then, a clay layer followed by a synthetic substance is set up, avoiding toxic waste substances leaching into the surrounding earth. Next, a number of drainage pipes and drainage tanks are facilitated, allowing waste liquid from the bottom of the landfill to go through.

After completing building the household waste landfill, it is ready to be filled with waste from a number of households in the area. The household waste would be gathered and poured into the huge man-made hole, while the waste liquid would be held in the drainage tanks, then eliminated via drainage pipes, in order to minimize a buildup of gas.

After being full of waste, the man-made hole will be covered by a thick clay layer, preventing a disgusting smell from going off. During the degradation of waste, biogas will be emitted into the environment.

Explanation: "Once the landfill is full of waste" is more formal and clearer than "After being full of waste," which is awkwardly phrased.
"a disgusting smell from going off" -> "the unpleasant odor from escaping"
Explanation: "The unpleasant odor from escaping" is more formal and precise than "a disgusting smell from going off," which is colloquial and vague.
"biogas will be emitted into the environment" -> "biogas is released into the environment"
Explanation: "Is released" is a more formal and accurate verb choice than "will be emitted," which is less commonly used in this context.

Band điểm Task Achivement ước lượng: 6

Band Score: 6.0

Explanation: The essay provides an overview of the main features of the landfill design, but it lacks clarity and detail in some areas. The essay identifies the three main stages of the process (construction, usage, and closure) and provides some information about each stage. However, the essay does not fully explain all of the key features of the design, such as the purpose of the drainage pipes and tanks, or the role of the clay layer in preventing the release of gases. The essay also includes some irrelevant details, such as the mention of "a disgusting smell" and "biogas being emitted into the environment."

How to improve: The essay could be improved by providing more detailed explanations of the key features of the landfill design. The essay could also be made more concise and focused by removing irrelevant details. For example, the essay could be improved by stating that the drainage pipes and tanks are used to collect and treat the liquid waste from the landfill, and that the clay layer is used to prevent the release of gases and leachate into the surrounding environment. The essay could also be improved by using more precise language and avoiding vague terms such as "a disgusting smell" and "biogas being emitted into the environment."

Band điểm Coherence & Cohesion ước lượng: 6

Band Score: 6.0

Explanation: The essay arranges information and ideas coherently, presenting a clear overall progression from construction to usage and finally closure of the landfill. However, while cohesive devices are used effectively, there are instances where cohesion between sentences could be improved, leading to a somewhat mechanical flow. The referencing is not always clear, particularly in the transition between ideas, and paragraphing is present but lacks logical separation of distinct stages in the landfill process.

How to improve: To enhance coherence and cohesion, the writer could work on the clarity of transitions between sentences and paragraphs. Using a wider variety of cohesive devices and ensuring that each paragraph clearly addresses a single aspect of the process would help. Additionally, improving referencing to avoid repetition and ensuring logical progression in paragraphing would further strengthen the organization of ideas.

Band điểm Lexical Resource ước lượng: 6

Band Score: 6.0

Explanation: The essay demonstrates an adequate range of vocabulary relevant to the task of describing the landfill process. The use of terms like "huge hole," "clay layer," "synthetic substance," and "drainage pipes" indicates an understanding of the topic. However, there are instances of awkward phrasing, such as "possibly capacity of household waste," which suggests a lack of precision. Additionally, there are some errors in word choice and formation, such as "preventing a disgusting smell from going off," which could be expressed more naturally. While the vocabulary is sufficient to convey the main ideas, the inaccuracies and occasional awkwardness limit the overall effectiveness.

How to improve: To enhance the lexical resource score, the writer should focus on using more precise and varied vocabulary. This includes avoiding awkward phrases and ensuring that word choices are appropriate for the context. Additionally, incorporating less common lexical items and ensuring correct collocations would demonstrate a higher level of sophistication.

The diagram illustrates the steps involved in creating a modern landfill for household waste.

Overall, it is evident that the design of a modern landfill for household waste comprises three main stages: construction, usage, and closure.

Regarding construction, a large hole is excavated in the natural rock to accommodate the capacity of household waste. Subsequently, a clay layer is installed, followed by a synthetic liner, which prevents toxic substances from leaching into the surrounding soil. Next, a series of drainage pipes and tanks are incorporated to facilitate the removal of liquid waste from the bottom of the landfill.

Once the construction of the household waste landfill is complete, it is prepared to receive waste from various households in the area. The household waste is collected and deposited into the large man-made hole, while the liquid waste is contained in the drainage tanks and then discharged through the drainage pipes to minimize the buildup of gas.

After the landfill reaches its capacity, the man-made hole is covered with a thick clay layer to prevent unpleasant odors from escaping. During the decomposition of waste, biogas is released into the environment.
