Module One: What is the Circular Economy?
Module Introduction
Hello, future changemaker! π Have you ever thought about where your things come from and where they go when you throw them away? Most things we use β like plastic bottles, clothes, and electronics β are used once and then thrown away. This is called a linear economy. But there is a better way β a circular economy. In a circular economy, we keep things in use, reduce waste, and give nature a chance to heal. In this module, we will learn what the circular economy is, why it matters, and how it works. Let's begin!
Learning Objectives
By the end of this module, you will be able to:
- Explain what the circular economy is.
- Understand the difference between linear and circular economies.
- Describe the three principles of the circular economy.
- Recognise why the circular economy is important.
- See examples of circular economy in everyday life.
Warm-up Story: The Tale of Two Villages
Once upon a time, there were two villages in Nigeria. In the first village, people used things once and threw them away. They cut down trees for firewood and never planted new ones. They threw their waste into the river. Over time, the river became dirty, and the land became barren. The village struggled.
In the second village, people were smarter. They fixed broken things instead of throwing them away. They composted food scraps and used them to grow new plants. They shared tools instead of buying new ones. The river was clean, the land was fertile, and the village thrived. The second village was using a circular economy. It's a system where nothing is wasted, and everything can be used again.
Main Lessons
Lesson 1: What is the Circular Economy?
Definition: The circular economy is an economic system where we keep resources in use for as long as possible, extract the maximum value from them, and then recover and regenerate products and materials at the end of their life.
Why it is important: It helps us reduce waste, protect the environment, and create a sustainable future.
Simple explanation: It's like a cycle β everything we use can be used again.
Real-life example: A company that collects used plastic bottles and recycles them into new bottles.
School example: A school that recycles paper and uses compost from food waste.
Home example: A family that repairs broken items instead of throwing them away.
Nigerian example: A Nigerian business that recycles plastic waste into building materials.
Illustration:
Circular Economy = Use β Reuse β Recycle β Regenerate
Mini summary: The circular economy is a system where we reuse and recycle things instead of throwing them away.
Lesson 2: The Linear Economy β Take, Make, Waste
Definition: The linear economy is the traditional way of doing business β we take resources, make products, use them, and throw them away.
Why it is important: It creates a lot of waste and harms the environment.

Real-life example: A plastic bottle is used once and thrown away.
School example: Students use single-use plastic water bottles.
Home example: A family throws away food scraps.
Nigerian example: Many products in Nigeria are used once and thrown away.
Illustration:
Linear Economy: Take β Make β Use β Waste
Mini summary: The linear economy is "take, make, waste" β it creates a lot of trash.
Lesson 3: The Circular Economy β A Better Way
Definition: The circular economy is the opposite of the linear economy β we keep things in use and avoid waste.
Why it is important: It saves resources, protects nature, and creates a better future.
Simple explanation: It's like a circle β everything comes back around.
Real-life example: A coffee shop that gives you a discount if you bring your own cup.
School example: A school that uses reusable lunch containers.
Home example: A family that reuses glass jars for storage.
Nigerian example: A Nigerian market that encourages reusable bags.
Illustration:
Circular Economy: Take β Make β Use β Reuse β Recycle β Regenerate
