Circular Business Models
Most businesses run in a straight line: buy materials, make something, sell it, and the customer throws it away. A circular model bends that line into a loop so materials come back and get used again. It is an environmental idea, but the exam wants you to treat it as a business one.
📘 What you need to know
A circular model aims to use fewer scarce resources and make less waste, while getting more value out of what it already has.
Materials are recycled, reused or regenerated instead of thrown away. It is sometimes called cradle-to-cradle.
Products are designed for long life, easy repair and easy recycling from the start.
Common approaches: design for longevity, resource efficiency, recycling and reuse, product as a service (renting instead of selling), biomimicry, and partnerships that create closed loops.
Benefits: lower waste, less dependence on scarce materials, cost savings, better reputation, more resilience when prices spike.
Costs: redesign, new suppliers, new logistics for collecting products back, and a change of mindset across the whole business.
Straight line versus loop
The extra arrow at the bottom is the whole business model. It also explains the extra cost: somebody has to get the product back.
The main approaches
Approach
What it means
What it looks like in practice
Design for longevity
Build things that last, so they are replaced less often
Stronger materials, spare parts kept in stock for years
Resource efficiency
Get more output from less input at every stage
Cutting patterns that waste less fabric, energy-saving machinery
Copy how nature solves the problem, where nothing is wasted
Packaging that breaks down like a leaf, cooling copied from termite mounds
Partnerships
Work with suppliers and others to close the loop
One firm’s offcuts become another firm’s raw material
Product as a service is the one worth understanding properly. If you rent a drill instead of selling it, you suddenly want it to last twenty years rather than two. The business model quietly changes what “good design” means.
Why a business would do this
Benefit
Cost or risk
Lower spending on raw materials over time
High set-up cost to redesign products and processes
Less exposure to shortages and price spikes
Reverse logistics: collecting used products back is expensive
Stronger reputation with customers who care
Accusations of greenwashing if the claims outrun the reality
Meets tightening waste and packaging laws early
Recycled inputs can be less consistent in quality
Opens new revenue from repairs, resale and rental
Selling fewer new units can cut short-term revenue
Payback is slow. Most of the cost of going circular lands in year one; most of the benefit arrives over five or ten years. That timing gap is the strongest argument against it for a business that is short of cash right now.
Worked examples
WORKED EXAMPLE
Define the term circular business model. [2 marks]
Step 1: the meaningA circular business model is one designed to cut the use of scarce resources and reduce waste by keeping materials in use for as long as possible [1].Step 2: add howProducts are recycled, reused, repaired or leased rather than being thrown away after a single use [1].2 marks“instead of throwing away” is the phrase that shows you understand the contrast
WORKED EXAMPLE
Loop Cycles repairs bikes in six workshops. It is considering a scheme to buy back old bikes, refurbish them and resell them. Discuss whether Loop should adopt this circular model. [10 marks — extract]
The case forLoop already employs trained mechanics, so refurbishment uses skills it has rather than skills it must buy. Refurbished bikes carry a higher margin than repairs because Loop controls the selling price, and the scheme fits a customer base that already values keeping a bike alive.The case againstBuying stock back ties up cash before any sale is made, and second-hand bikes vary so much in condition that repair time is hard to forecast. Loop would also need storage space in six city-centre sites where rent is high.JudgementLoop should trial the scheme in one workshop first. That caps the cash tied up, gives real data on refurbishment time, and lets it scale up only if the margin holds.Trial it in one site, then decide“trial it first” is a genuinely good business answer, not a fence-sit, as long as you say why
💡 Exam tips
Treat it as a business decision with costs and revenues, not just an environmental one.
Name the approach: “product as a service”, “design for longevity”. Precise terms score.
Always mention reverse logistics. Getting the product back is the part most answers forget.
Link it to STEEPLE. Environmental rules and ethical expectations are what push firms this way.
For judgement, weigh short-term cost against long-term saving and say which matters more for this business.
Watch for a case study where the firm is small. Small firms often cannot fund the redesign.
⚠ Common mix-ups
Thinking circular just means recycling. Recycling is one of six or so approaches.
Assuming it always saves money. Early on it usually costs more.
Forgetting the customer. Some buyers will not accept refurbished goods.
Writing a general essay on the environment with no reference to the business in the case study.
Ignoring the revenue risk of selling fewer new units.
Claiming it removes all waste. It reduces waste; nothing removes it entirely.
