Definition
What is it?
Recycled plastics are old plastic items that have been collected, cleaned, and processed so they can be used again to make new products. Instead of throwing plastic away, we give it a new life.
Simple Example
Quick Example
Imagine you finish a bottle of 'Frooti' mango juice. Instead of tossing it in the normal dustbin, you put it in a separate bin for plastics. This bottle, along with many others, then goes to a factory to be recycled and might come back as a new toy or a part of a school bench.
Worked Example
Step-by-Step
Let's see how much plastic waste can be saved from going into a landfill by recycling.
Step 1: A small school collects 100 empty plastic water bottles every day.
---Step 2: If they recycle these bottles for 5 days, the total bottles collected for recycling are 100 bottles/day * 5 days = 500 bottles.
---Step 3: If each bottle weighs about 20 grams, the total weight of plastic recycled is 500 bottles * 20 grams/bottle = 10,000 grams.
---Step 4: Since 1000 grams = 1 kilogram, the total plastic recycled is 10,000 grams / 1000 grams/kg = 10 kg.
---Answer: The school helped recycle 10 kg of plastic in 5 days, preventing it from becoming waste.
Why It Matters
Recycled plastics are super important for protecting our planet! They help reduce pollution, save energy, and conserve natural resources. Engineers use recycled plastics to build parts for electric vehicles (EVs) and even components for robots, creating exciting career paths in sustainable technology and manufacturing.
Common Mistakes
MISTAKE: Thinking all plastic can be recycled together. | CORRECTION: Different types of plastics (like PET bottles and plastic bags) need to be separated for proper recycling, as they are processed differently.
MISTAKE: Believing recycled plastic is always weaker or lower quality. | CORRECTION: While some recycled plastic might be used for different products, advanced technologies can now make recycled plastic almost as strong and durable as new plastic.
MISTAKE: Throwing dirty plastic containers into the recycling bin. | CORRECTION: Plastic items should be rinsed clean of food or liquid residue before recycling, otherwise they can contaminate the whole batch.
Practice Questions
Try It Yourself
QUESTION: Why is it good to recycle a plastic bottle instead of throwing it away? | ANSWER: Recycling helps save resources, reduces pollution, and lessens the amount of waste in landfills.
QUESTION: If a family uses 5 plastic milk pouches a day, and they recycle them, how many pouches will they recycle in a week? | ANSWER: 5 pouches/day * 7 days/week = 35 pouches in a week.

To make them stronger than new plastic
The Correct Answer Is:
B
The main purpose of recycling is to collect old materials like plastic and process them so they can be reused to create new products, reducing waste and conserving resources. Options A, C, and D are incorrect descriptions of the recycling process or its primary goal.
Real World Connection
In the Real World
In India, many companies like 'Reliance Industries' and 'Bisleri' have initiatives to collect and process plastic waste. You might see ragpickers (waste pickers) in your city collecting plastic bottles and other items, which are then sorted and sent to recycling units. These recycled plastics are often used to make new products like roadside benches, clothes, or even parts for household appliances.
