IELTS Reading Practice: How to Reduce Household Waste Through Composting

IELTS Reading is a challenging component of the test, requiring candidates to demonstrate their ability to understand complex texts and answer various question types within a limited time frame. Today, we’ll focus on a topic that has gained significant attention in recent years: reducing household waste through composting. This subject has appeared in several IELTS tests over the past decade, reflecting its growing importance in environmental discussions. Given the increasing emphasis on sustainability and waste management, there’s a high likelihood that similar topics will continue to feature in future IELTS exams.

Let’s dive into a practice reading passage on this crucial environmental issue, followed by a set of questions to test your comprehension and analytical skills.

Reading Passage

Composting: A Natural Solution to Household Waste

Household waste is a growing concern in many countries, with landfills reaching capacity and incineration posing environmental risks. However, a significant portion of household waste can be diverted from these disposal methods through a simple, natural process: composting. This age-old practice not only reduces the amount of waste sent to landfills but also produces a valuable resource for gardening and agriculture.

Composting is the biological decomposition of organic matter under controlled conditions. It’s a process that occurs naturally in forests, where fallen leaves and other organic materials break down over time to enrich the soil. In a household setting, composting can be done in a designated bin or pile, where kitchen scraps, yard trimmings, and other biodegradable materials are combined and left to decompose.

The composting process requires four key elements: organic matter, moisture, oxygen, and bacteria. The organic matter provides food for the bacteria, which break down the materials. Moisture and oxygen are necessary for the bacteria to thrive and carry out their decomposition work. When these elements are balanced correctly, the compost pile will heat up as the bacteria multiply and break down the organic matter. This heat accelerates the decomposition process and helps to kill weed seeds and harmful pathogens.

Materials suitable for composting include fruit and vegetable scraps, coffee grounds, tea bags, eggshells, yard trimmings, and shredded paper. However, it’s important to avoid adding meat, dairy products, or oily foods, as these can attract pests and create unpleasant odors. Additionally, diseased plants, pet waste, and chemically treated wood should be kept out of the compost pile to prevent the spread of harmful substances.

There are several methods of composting suitable for households, depending on available space and the amount of organic waste produced. For those with outdoor space, a simple compost pile or bin can be set up in the garden. Urban dwellers with limited outdoor space can opt for indoor composting systems, such as worm bins (vermicomposting) or bokashi buckets, which use anaerobic fermentation to break down organic matter.

The benefits of composting extend beyond waste reduction. The finished compost is a nutrient-rich soil amendment that can improve soil structure, enhance water retention, and provide essential nutrients for plant growth. By using compost in gardens and landscapes, households can reduce their reliance on chemical fertilizers, further benefiting the environment.

Moreover, composting can have a significant impact on reducing greenhouse gas emissions. When organic waste decomposes in landfills, it produces methane, a potent greenhouse gas. By composting this waste instead, methane emissions are reduced, and carbon is sequestered in the soil when the compost is used.

Implementing a household composting system does require some effort and knowledge. However, with proper management, it can become a simple and rewarding part of daily life. Many local governments and environmental organizations offer workshops and resources to help residents start composting. Some municipalities even provide subsidized compost bins or collect organic waste for large-scale composting facilities.

As awareness of environmental issues grows, more households are turning to composting as a way to reduce their waste and contribute to a more sustainable future. By transforming kitchen scraps and yard waste into valuable compost, individuals can play a significant role in addressing the challenges of waste management and soil degradation, one household at a time.

Common Mistakes

When tackling IELTS Reading questions on topics like composting and waste reduction, candidates often make the following mistakes:

1. Overlooking key words: In True/False/Not Given questions, missing crucial words like “all” in statement 3 can lead to incorrect answers.

2. Confusing similar information: For Multiple Choice questions, carefully distinguish between mentioned and unmentioned benefits.

3. Misinterpreting headings: In Matching Headings tasks, ensure you understand the main idea of each paragraph, not just individual details.

4. Inserting personal knowledge: Especially in Summary Completion tasks, use only information from the passage, avoiding the temptation to fill gaps with external knowledge.

5. Neglecting context: In all question types, consider the broader context of the information within the passage to avoid misinterpretations.

Vocabulary

Here are some challenging words from the passage, along with their definitions:

1. Incineration (noun) /ɪnˌsɪnəˈreɪʃn/: The process of burning something completely
2. Biodegradable (adjective) /ˌbaɪəʊdɪˈɡreɪdəbl/: Capable of being decomposed by bacteria or other living organisms
3. Pathogens (noun) /ˈpæθədʒənz/: Bacteria, viruses, or other microorganisms that can cause disease

Grammar Focus

Pay attention to the use of conditional sentences in environmental contexts:

“With proper management, it can become a simple and rewarding part of daily life.”

This is an example of a first conditional sentence, used to discuss realistic possibilities. The structure is:

If/When + present simple, will/can + infinitive

Practice using this structure to discuss potential environmental solutions:

“If more people compost their organic waste, landfills will receive less garbage.”
