Test: Waste Disposal - Primary 5 MCQ

Biodegradable waste should be disposed of in the green bin. This color-coding helps in the effective segregation of waste, facilitating proper recycling and composting processes.

Increasing waste is NOT a benefit of recycling. In fact, recycling helps to reduce waste, conserve resources, and minimize the amount of material that ends up in landfills.

The key strategy to conserve the environment is to practice the three R's: reduce, reuse, and recycle. These principles help minimize waste, conserve resources, and reduce environmental impact.

In the context of waste management, "refuse" means to say no to harmful products that can damage the environment. This proactive approach helps in reducing waste generation from the outset.

New batteries can be made from recycled materials. Recycling old batteries helps recover valuable metals and reduces the environmental impact associated with battery production, promoting sustainability.

Buying in bulk is an example of reducing waste, as it often involves less packaging and minimizes the number of containers needed, thus reducing overall waste generation.

Using less packaging is part of the "reduce" strategy. By choosing products with minimal packaging, we can significantly decrease the amount of waste generated, which helps protect the environment.

Reusing items effectively means using them for different purposes instead of discarding them. For example, old jars can be used for storage, which extends their life and reduces waste.

Recycling involves turning old materials into new products. This process saves natural resources and reduces pollution, making it an essential part of waste management strategies.

Keeping waste in covered dustbins is important to prevent odors and deter pests. This practice helps maintain cleanliness and hygiene in living environments, reducing health risks associated with open waste.

Glass is an example of non-biodegradable waste. Unlike biodegradable materials that decompose, glass does not break down easily and can remain in the environment for a long time, contributing to pollution.

Donating old clothes is a great way to reuse items instead of discarding them. This not only helps those in need but also reduces waste and promotes a culture of sharing and sustainability.

Using cloth bags instead of plastic bags helps reduce pollution and waste. Cloth bags are reusable and do not contribute to the plastic waste problem that harms ecosystems and wildlife.

Separating waste into biodegradable and non-biodegradable types is crucial for proper waste disposal. This practice helps in efficient recycling and reduces the environmental impact of waste.

Improperly disposed waste harms aquatic life by causing water pollution. Contaminants can lead to the death of fish and other organisms, disrupt ecosystems, and pose health risks to humans relying on clean water.

Throwing waste in open areas leads to air and water pollution. This not only creates unpleasant odors but also poses health risks to humans and wildlife, making proper disposal essential.

Food scraps are an example of biodegradable waste. They can decompose and enrich the soil, making them beneficial for the environment when disposed of properly.

The primary purpose of waste management is to keep our surroundings clean and safe. Proper waste disposal prevents pollution and protects public health by reducing bad smells and the spread of diseases, ensuring a cleaner environment for everyone.

Ragpickers play a crucial role in recycling by collecting recyclable materials from waste. They help ensure that valuable resources are processed correctly and kept out of landfills, contributing to environmental conservation.

Biodegradable waste is capable of decomposing and mixing with soil. This type of waste, such as vegetable peels and paper, is not harmful to the environment as it breaks down naturally, contributing to soil health.
