SERIES: Sustainability and the Circular Economy

S4-S6 / Adult

What Is the Circular Economy? Design, Reuse and Regeneration

Recycling matters, but it is only one part of a circular economy. Materials can still be lost through contamination, poor design, downcycling or systems that make reuse and repair difficult. You will audit a real waste stream, trace one material journey and identify where higher-value circular action could happen. By the end of this […]

What Is the Circular Economy? Design, Reuse and Regeneration

Your Mission

Investigate what really happens to waste and move the conversation beyond ‘just recycle more’.

You will run a safe waste audit, trace one material through the real system and recommend higher-value circular actions.

️ Think & apply

Discover

Start by exposing the assumptions hidden behind the bin.

Step 1

What Happens After the Bin?

️ Predict the journey · 8–10 mins

We are learning to question assumptions about where materials go after disposal.

A recycling symbol, recycling bin or ‘recyclable’ label does not guarantee that a material becomes a new product.

Your Task

Choose five common waste items.
Predict where each goes after collection.
Mark each prediction confident, unsure or guess.
Choose the item whose journey you most need to verify.

I can identify gaps in my understanding of real waste journeys.

→ This gives your investigation a clear set of claims to test.

Step 2

Run a Safe Waste Audit

️ Tally + classify · 10–12 mins

We are learning to collect simple evidence about the materials moving through a real setting.

A small audit can reveal what is actually being discarded, not what people remember throwing away.

Your Task

Use a safe teacher-provided sample, dataset or observation area.
Record at least 20 items or observations by material/category.
Mark whether each item appears reusable, repairable, recyclable locally, compostable or residual.
Calculate the three largest categories.

I can collect and classify waste data safely and consistently.

→ This gives your final report evidence from a real system.

ResearchData LiteracySystems Thinking

Explore

Use real evidence to trace materials and identify where value is lost.

Step 3

Trace One Material for Real

Choose your route · 12–15 mins

We are learning to investigate what actually happens to a material after collection.

Focus on the real local or national system: collection, sorting, contamination, processing and what the recovered material can become.

Your Task

Choose one common material from your audit.
Complete one research route.
Map at least four stages after disposal.
Identify one point where material value is commonly lost.

⚡ Quick Track

Use local authority, waste-management or credible recycling information to trace the material from collection through sorting and processing.

Dig Deeper

Use two sources to compare the ideal recycling route with real-world losses such as contamination, downcycling, export or lack of market demand.

I can trace a real material journey using evidence rather than recycling assumptions.

→ This gives your Waste Intelligence Report a verified process map.

Step 4

Move Up the Circular Hierarchy

✏️ Redesign the response · 10–12 mins

We are learning to compare recycling with strategies that prevent waste or preserve more product value.

Circularity often works best when products stay whole for longer.

Your Task

Take the three largest waste categories from your audit.
For each, propose one action at a higher-value level: avoid/reduce, reuse/share, repair/refill or recycle/compost.
Choose the strongest intervention.
Explain what behaviour, infrastructure or design change it requires.

I can prioritise waste prevention and value retention rather than defaulting to recycling.

→ This becomes the recommendation section of your report.

Problem SolvingCritical ThinkingEnvironmental Awareness

Create & Share

Create a Waste Intelligence Report with practical circular recommendations.

Step 5

Create a Waste Intelligence Report

✏️ Analyse · Create · 25–35 mins

We are learning to communicate what a real waste system is losing and how circular action could improve it.

Your report should connect local evidence, one verified material journey and practical recommendations.

Your Task

Include the three biggest waste categories from your audit.
Show one verified material journey.
Identify at least one loss or barrier in the current system.
Recommend three actions, including at least one above recycling in the circular hierarchy.
Choose one output below.

Waste Intelligence Report

1 page · 300–350 words + small data table

⏱ 25–30 mins

Summarise the audit, material journey, losses and three recommendations.

Where Our Waste Really Goes

4 slides · maximum 30 words per slide

⏱ 30–35 mins

Present audit data, one material journey, the system gap and your circular response.

Beyond the Recycling Bin

90 seconds final runtime

⏱ 30–35 mins

Explain why recycling alone is not circular and what your evidence suggests should happen first.

I can create an evidence-based waste report with practical circular recommendations.

→ This is your finished mission output.

Step 6

Reflect, Apply, Look Forward

️ Think or discuss · 5–8 mins

We are learning to reflect on how evidence changed my assumptions about waste.

The next challenge applies life-cycle thinking to fashion, where material, production, use and disposal decisions are tightly connected.

Your Task

Answer the prompts.
Name one waste assumption your investigation changed.
Write one question you now have about how a product was designed before it became waste.

Reflect

Which material journey was most different from what you expected?

Apply

What one waste-system change could your school or workplace test now?

Look Forward

How could better product design reduce the need for waste infrastructure altogether?

I can explain why circular economy thinking begins before disposal.

→ You are ready to analyse a product across its full life cycle.

TOOLKIT

Choose Your Tools

Use the tools available to you. Strong systems thinking and evidence matter more than the software.

Audit

Use a safe household, school or workplace waste sample without handling hazardous waste. A teacher-provided dataset is also valid.

Research

Check what actually happens to different materials locally or nationally. Do not assume that putting something in a recycling bin guarantees recycling.

Create

Use a waste-flow map, intelligence report, slides or short explainer.

Educator / Parent Notes

Age, Stage and Prior Learning: Designed for S4–S6 and adults. Learners should never handle hazardous, sharp, contaminated or unknown waste.

Before You Start: Use a teacher-provided dataset or visual audit if direct observation is unsuitable. Check local recycling guidance so learners do not assume national rules apply everywhere.

How to Open This: Ask: “If something goes into a recycling bin, has it been recycled?” Use the uncertainty to open the investigation.

Scheduling: Steps 1–4 need around 40–50 minutes. Step 5 needs 25–35 minutes. The audit can be completed in advance or supplied as data.

If a Pupil Gets Stuck: Provide a waste-category checklist and one material journey to investigate. Reduce the audit sample rather than removing the evidence step.

For Fast Finishers: Ask learners to calculate proportions, compare two material routes or estimate the impact of preventing the largest waste category.

Marking Guidance: Look for real audit/data evidence, an accurate material journey, understanding of system losses and recommendations that prioritise prevention, reuse or repair where appropriate.
