FAQs on Understanding: Reduce, Recycle and Reuse Video Lecture - Basic Science for Primary 5

1. What are the three Rs in waste management?
Ans. The three Rs in waste management are Reduce, Recycle, and Reuse. These principles aim to minimize waste generation, promote the recycling of materials, and encourage the reuse of products or items whenever possible.
2. How can we reduce waste in our daily lives?
Ans. We can reduce waste in our daily lives by adopting practices such as using reusable bags instead of plastic ones, opting for products with minimal packaging, avoiding single-use items like plastic straws and bottles, composting organic waste, and donating or selling items we no longer need instead of throwing them away.
3. What is the difference between recycling and reusing?
Ans. Recycling involves the process of converting waste materials into new products. It requires energy and resources to transform the materials into something new. Reusing, on the other hand, involves using an item or product multiple times without the need for any significant processing or transformation. It helps to extend the lifespan of a product and reduce the overall waste generated.
4. How does recycling benefit the environment?
Ans. Recycling benefits the environment in several ways. It helps conserve natural resources by reducing the need for raw materials. It saves energy as the production of recycled materials requires less energy compared to producing new ones. Recycling also reduces the amount of waste sent to landfills, which helps prevent pollution and the release of greenhouse gases.
5. What are some examples of reusing items?
Ans. Some examples of reusing items include using glass jars as storage containers, repurposing old t-shirts into cleaning rags, using old newspapers for wrapping delicate items, donating clothes or toys to others, and using rechargeable batteries instead of disposable ones. Reusing items helps reduce waste and extends the lifespan of products.
