Module Introduction

Hello, future changemaker! 🌍 Have you ever thought about where your things come from and where they go when you throw them away? Most things we use – like plastic bottles, clothes, and electronics – are used once and then thrown away. This is called a linear economy. But there is a better way – 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

  Circular Economy = Use → Reuse → Recycle → Regenerate
      

  Linear Economy: Take → Make → Use → Waste
      

  Circular Economy: Take → Make → Use → Reuse → Recycle → Regenerate
      

  3 Principles:
  1. Eliminate waste
  2. Keep materials in use
  3. Regenerate nature
      

  Eliminate Waste = Design out pollution
      

  Keep in Use = Repair, reuse, recycle
      

  Regenerate = Restore nature
      

  Why it Matters: Protect planet, save resources, create jobs
      

  Everyday Circular:
  - Reuse
  - Recycle
  - Repair
  - Reduce
      

  Nigeria & Circular Economy:
  - Recycling
  - Waste-to-energy
  - Local solutions
      

  Fun Circular Activities:
  - Craft from waste
  - Compost club
  - Reuse challenge
      

  Mistakes:
  - Only recycling
  - Not reducing
  - Ignoring repair
      

  Best Practices:
  1. Reduce
  2. Reuse
  3. Repair
  4. Recycle
      

  Did You Know?
  - 2 billion tons of waste/year
  - Plastic takes 450 years to decompose
      

  The Future is Circular! 🌍
      

Key Vocabulary (simple definitions)

• Circular Economy: A system where we reuse and recycle things.
• Linear Economy: Take, make, waste – the traditional way.
• Waste: Things we throw away.

• Everyone can participate: Individuals, businesses, and governments can be part of the circular economy.

Step-by-Step Explanations

How to Start Practicing Circular Economy

1. Reduce what you buy – only buy what you need.
2. Reuse items – use them again instead of throwing them away.
3. Repair broken items – fix them instead of replacing them.
4. Recycle what you can – turn waste into new products.
5. Compost food scraps – turn them into soil.

Teacher Notes

• Use the village story to explain linear vs circular economies.
• Encourage students to think of examples in their daily lives.
• Discuss the three principles with simple examples.
• Use Nigerian examples to make it locally relevant.

Parent Tips

Warm-up Story: The Market Stall

In a busy market in Lagos, there was a woman named Mama Kemi who sold fruit. She noticed that many of her customers threw away fruit peels. She had an idea – she started collecting the peels and turned them into organic fertiliser. She sold the fertiliser to farmers. She used the same fruit to sell fresh fruit and fertiliser – nothing went to waste. Mama Kemi had created a circular business model. She used the Circular Business Model Canvas to think about her customers, her products, and how to make money while helping the environment.

Preparation for the Next Module

In Module 3, we will learn about Product-as-a-Service – a circular model where you sell access instead of ownership. You'll learn how businesses rent, lease, and offer services instead of selling products. Get ready!

Module Introduction

Hello, service innovator! 🔄 In Module 2, you learned how to design a circular business using the Canvas. Now it's time to explore a powerful circular model called Product-as-a-Service (PaaS). Instead of selling a product and forgetting about it, you sell the service that the product provides. For example, instead of buying a washing machine, you can rent it by the month. The company keeps the product, maintains it, and takes it back when you're done. This keeps resources in use and reduces waste. Let's learn how this works!

Learning Objectives

By the end of this module, you will be able to:

• Explain what Product-as-a-Service (PaaS) is.
• Understand the benefits of PaaS.
• Identify different types of PaaS models.
• See examples of PaaS in real life.
• Apply PaaS to your own business ideas.

Warm-up Story: The Bicycle Share

In a busy city in Nigeria, there was a company called "RideEasy." Instead of selling bicycles, they offered a service – you could rent a bicycle for a day, a week, or a month. You paid a small fee, used the bicycle, and returned it. They took care of maintenance and repairs. This meant fewer bicycles needed to be made, and people could use them without buying one. This is Product-as-a-Service – selling the use of a product, not the product itself.

Main Lessons

  Product-as-a-Service = Sell the service, not the product
      

  PaaS = Circular because it extends product life
      

  Types of PaaS:
  - Rental (short-term)
  - Leasing (long-term)
  - Subscription (ongoing)
  - Pay-per-use (per use)
      

  Rental = Short-term use, pay a fee
      

  Leasing = Long-term use, regular payments
      

  Subscription = Regular fee for ongoing access
      

  Pay-Per-Use = Pay only for what you use
      

  Benefits: Regular revenue, loyalty, sustainability
      

  Benefits: Lower cost, no maintenance
      

  Nigerian PaaS:
  - Solar home systems
  - Generator rentals
  - Equipment leasing
      

  Steps to Start PaaS:
  1. Choose a product
  2. Decide payment model
  3. Plan maintenance
  4. Market the service
      

  Mistakes:
  - Poor maintenance
  - Wrong pricing
  - Hidden costs
      

  Best Practices:
  - Regular maintenance
  - Clear pricing
  - Good customer service
      

  Fun PaaS:
  - Toy rentals
  - Book rentals
  - Game rentals

Preparation for the Next Module

In Module 4, we will explore Sharing and Access Models – how platforms like Uber, Airbnb, and peer-to-peer sharing are changing how we use resources. Get ready to learn about the sharing economy!

Module Introduction

Hello, community builder! 🤝 In Module 3, you learned about Product-as-a-Service. Now we are going to explore another exciting circular model: sharing and access models. These models are about sharing resources with others instead of owning everything yourself. Platforms like Uber, Airbnb, and car-sharing services are great examples. When we share, we use fewer resources and create stronger communities. In this module, we will learn how sharing works, why it's circular, and how it benefits everyone. Let's share!

Learning Objectives

By the end of this module, you will be able to:

• Explain what sharing and access models are.
• Understand the sharing economy.
• Identify different types of sharing models.
• See examples of sharing in Nigeria and around the world.
• Understand the benefits of sharing for people and the planet.

Warm-up Story: The Community Tool Shed

In a small Nigerian community, there was a tool shed where people could borrow tools. Instead of everyone buying their own hammer, drill, or ladder, they shared. One person would use the drill today, and another would use it tomorrow. This saved money and resources. The community was stronger because people helped each other. This is a sharing and access model – sharing resources instead of owning them individually.

Main Lessons

  Sharing = Using something together
      

  Sharing Economy = Sharing access to goods and services
      

  Peer-to-Peer = People sharing directly with each other
      

  Platform = App that connects people for sharing
      

  Car Sharing = Sharing vehicles
      

  Home Sharing = Sharing living spaces
      

  Tool Sharing = Sharing tools and equipment
      

  Clothing Sharing = Rent or swap clothes
      

  Food Sharing = Sharing food to reduce waste
      

  Benefits: Save money, reduce waste, build community
      

  Nigerian Sharing:
  - Ride-sharing (Bolt, Uber)
  - Community sharing
  - Food sharing
      

  Mistakes:
  - Low trust
  - Poor maintenance
  - Unclear rules
      

  Best Practices:
  - Build trust
  - Clear rules

Preparation for the Next Module

In Module 6, we will explore Recycling and Upcycling – turning waste into valuable resources. You'll learn how materials can be recovered and transformed into new products. Get ready to turn trash into treasure!

Module Introduction

Hello, supply chain explorer! 📦 In Module 6, you learned about recycling and upcycling. Now we are going to learn about circular supply chains – how materials flow from sourcing to production to use and back again. A linear supply chain goes one way – take, make, waste. A circular supply chain loops back – materials are recovered and reused. In this module, we will learn how circular supply chains work, why they matter, and how they are used in Nigeria and around the world. Let's follow the flow!

Learning Objectives

By the end of this module, you will be able to:

• Explain what a circular supply chain is.
• Understand the difference between linear and circular supply chains.
• Identify the stages of a circular supply chain.
• See examples from Nigeria and the world.
• Understand the benefits for the environment and economy.

Warm-up Story: The Farmer's Cycle

In a Nigerian village, a farmer named Musa grew cassava. He sold the cassava to a processor who made garri. The peels and waste from the processing were given to Musa's neighbour, who used them to feed his goats. The goats produced manure, which Musa used to fertilise his farm. Nothing was wasted – everything flowed in a circle. This is a circular supply chain – where materials are continuously reused. Let's learn how this works in business!

Main Lessons

  Circular Supply Chain = Loop of materials
      

  Linear: Take → Make → Use → Waste
  Circular: Take → Make → Use → Recover → Reuse → Recycle
      

  Stages: Sourcing → Production → Distribution → Use → Recovery
      

  Sourcing = Get materials sustainably
      

  Production = Make products efficiently
      

  Distribution = Deliver products efficiently
      

  Use = Use products longer and repair
      

  Recovery = Collect used products for reuse
      

  Reverse Logistics = Products return for recovery
      

  Benefits: Reduce waste, lower costs, protect environment
      

  Nigerian Examples:
  - Agricultural waste recycling
  - Electronics take-back
  - Local material sourcing
      

  Challenges:
  - Cost
  - Infrastructure
  - Awareness
      

  Best Practices:
  - Design for circularity
  - Collaborate with partners
  - Educate customers
      

  Fun Activities:
  - Trace a product's journey
  - Recycling projects
  - Composting experiments

Module Introduction

Hello, change maker! 🌍 In Module 10, you learned about circular metrics and how to measure impact. Now we are going to explore the barriers and enablers of the circular economy – what stops us from being circular and what helps us move forward. Barriers are like roadblocks, and enablers are like tools that help us overcome them. In this module, we will learn about policies, consumer behaviour, technology, and more. Let's understand the challenges and opportunities!

Learning Objectives

By the end of this module, you will be able to:

• Explain what barriers and enablers are.
