FAQs on Fun Video: What Happens to Plastic after it is Discarded? Video Lecture - Basic Science for Primary 5

1. What happens to plastic after it is discarded?
Ans. When plastic is discarded, it can go through different processes based on how it is managed. Some plastic waste may end up in landfills, where it can take hundreds of years to decompose. Others may be incinerated, which can release harmful pollutants into the air. Recycling is another option, where plastic waste is collected, sorted, and processed to be reused in the production of new plastic products.
2. How long does it take for plastic to decompose?
Ans. The time it takes for plastic to decompose depends on the type of plastic and the environmental conditions. Some types of plastic, like PET bottles, can take around 450 years to decompose in a landfill. Other types, like plastic bags, can take anywhere from 10 to 1,000 years. However, it's important to note that even when plastic decomposes, it breaks down into smaller microplastics that can persist in the environment for much longer.
3. Is plastic recycling effective?
Ans. Plastic recycling can be effective in reducing the amount of plastic waste that ends up in landfills or the environment. However, its effectiveness depends on various factors, such as the availability of recycling facilities, the quality of the recycled plastic, and the demand for recycled materials. It is essential to promote proper sorting and recycling practices to ensure that the recycled plastic is of high quality and can be used in the production of new products.
4. Are there any alternatives to plastic?
Ans. Yes, there are alternatives to plastic that can help reduce plastic waste. Some alternatives include using reusable bags made of fabric or other materials instead of plastic bags, using glass or stainless steel containers instead of plastic ones, and opting for natural materials like bamboo or paper for packaging. It is important to consider the lifecycle impact of alternative materials to ensure they are sustainable and environmentally friendly.
5. How can individuals reduce plastic waste?
Ans. Individuals can take several steps to reduce plastic waste. Some of the measures include using reusable bags and water bottles, avoiding single-use plastic items like straws and cutlery, recycling plastic products properly, and supporting businesses that use sustainable packaging. Additionally, spreading awareness and advocating for policies that encourage plastic waste reduction can have a significant impact on overall plastic waste management.
