BMT 8 - Circular Business Models
Sustainable Business Models for a Regenerative Economy
1. What are Circular Business Models?
Circular Business Models are business strategies that aim to minimize waste, maximize resource efficiency, and create closed-loop systems where products, materials, and resources are reused, repaired, refurbished, remanufactured, or recycled rather than disposed of after use.
Core principle: Keep resources in use for as long as possible, extract maximum value during use, then recover and regenerate products and materials at the end of their service life.
Goal: Decouple economic growth from resource consumption and environmental degradation by creating regenerative systems.
Key characteristics of circular business models:
- Closed-loop systems: Materials circulate within the economy rather than becoming waste
- Product longevity: Products designed for durability and multiple lifecycles
- Resource efficiency: Maximum value extracted from minimal resources
- Waste elimination: Waste from one process becomes input for another
- Renewable inputs: Preference for renewable and regenerative resources
- Value retention: Maintain product and material value throughout lifecycle
2. Linear Economy vs. Circular Economy
The Linear Economy Model
Linear Economy (also called "Take-Make-Dispose" model) is the traditional economic system where resources are extracted, made into products, used, and then discarded as waste.
Linear flow:
EXTRACT → PRODUCE → CONSUME → DISPOSE
Characteristics of Linear Economy:
- Resource extraction: Continuous mining of virgin materials
- One-way flow: Materials move in single direction toward waste
- Planned obsolescence: Products designed to have limited lifespan
- Disposal culture: "Use and throw away" mentality
- Waste generation: End-of-life products become landfill
- Environmental degradation: Resource depletion and pollution
Problems with Linear Economy:
- Resource scarcity: Finite resources being depleted rapidly
- Environmental damage: Extraction and disposal harm ecosystems
- Waste crisis: Landfills and ocean pollution overwhelming
- Climate change: High carbon emissions from production and waste
- Economic vulnerability: Dependence on volatile commodity prices
- Value loss: Products discarded while still containing valuable materials
The Circular Economy Model
Circular Economy is a regenerative system where resource input, waste, emissions, and energy leakage are minimized by slowing, closing, and narrowing material and energy loops.
Circular flow:
DESIGN → PRODUCE → USE → RETURN → REGENERATE ↻
Characteristics of Circular Economy:
- Regenerative design: Products designed for multiple lifecycles
- Closed loops: Materials continuously circulate
- Value retention: Keep products and materials at highest value
- Systems thinking: Consider entire lifecycle and ecosystem
- Renewable energy: Powered by renewable sources
- Collaborative consumption: Sharing, renting, product-as-service
Comparison: Linear vs. Circular Economy
| Aspect | Linear Economy | Circular Economy |
|---|---|---|
| Flow Pattern | One-way (extract → dispose) | Circular loops (continuous cycles) |
| Resource Use | Virgin materials extracted continuously | Materials reused and recycled repeatedly |
| Product Design | Disposability, planned obsolescence | Durability, repairability, modularity |
| End of Life | Waste disposal (landfill, incineration) | Recovery, regeneration, reuse |
| Business Model | Sell products, high volume turnover | Services, leasing, take-back systems |
| Value Creation | From selling new products | From keeping resources in use |
| Environmental Impact | High (resource depletion, pollution) | Low (regenerative, restorative) |
| Economic Logic | Growth through increased production | Growth through resource productivity |
3. Core Principles of Circular Economy
The Ellen MacArthur Foundation identifies three core principles:
Principle 1: Design Out Waste and Pollution
Concept: Waste and pollution are design flaws that can be eliminated through better product design and business models.
Application:
- Design products for disassembly and material recovery
- Use non-toxic, recyclable materials
- Eliminate single-use plastics and packaging
- Create products that generate no harmful waste
- Design for energy efficiency and renewable energy use
Example: Patagonia designs jackets that can be easily repaired and recycled, with modular components that can be replaced rather than discarding entire garment.
Principle 2: Keep Products and Materials in Use
Concept: Maximize the useful life of products and materials through maintenance, repair, refurbishment, remanufacturing, and recycling.
Strategies (R-Strategies Framework):
- Refuse: Prevent unnecessary consumption
- Reduce: Use fewer resources and materials
- Reuse: Use products multiple times for same purpose
- Repair: Fix broken products to extend lifespan
- Refurbish: Restore products to working condition
- Remanufacture: Disassemble and rebuild to like-new condition
- Repurpose: Use products for different purpose
- Recycle: Process materials into new products
- Recover: Extract energy from waste materials
Example: Caterpillar remanufactures heavy machinery components, saving 85% of energy compared to producing new parts.
Principle 3: Regenerate Natural Systems
Concept: Return valuable nutrients to the soil and other ecosystems, moving beyond "do no harm" to actively improving the environment.
Application:
- Use renewable and regenerative resources
- Return biological materials to soil through composting
- Restore degraded land and ecosystems
- Support biodiversity and natural capital
- Create positive environmental outcomes
Example: Interface carpets designed to biodegrade safely, returning nutrients to soil rather than persisting in landfills for centuries.
4. Types of Circular Business Models
1. Product-as-a-Service (PaaS)
Model: Customers pay for access to products or their functions rather than owning them. Business retains ownership and responsibility for maintenance, repair, and end-of-life management.
How it works:
- Company leases products to customers
- Revenue from ongoing service fees rather than one-time sale
- Incentive to design durable, long-lasting products
- Company maintains and upgrades products
- Products returned at end of contract for refurbishment or recycling
Benefits:
- Customers avoid high upfront costs
- Always access to latest technology through upgrades
- Business has recurring revenue stream
- Company incentivized to maximize product lifespan
Examples:
- Philips Lighting: "Light as a Service" - sell lighting services rather than bulbs, retaining ownership and responsibility for maintenance
- Rolls-Royce: "Power by the Hour" - airlines pay for engine running time, not engine purchase
- Mud Jeans: Lease jeans to customers, take back for recycling into new jeans
2. Sharing Platforms
Model: Enable multiple users to access and share underutilized products or assets, maximizing utilization rates and reducing need for ownership.
How it works:
- Platform connects owners with users
- Products shared among multiple users
- Increased utilization of existing assets
- Reduced need for individual ownership
Examples:
- Airbnb: Share residential space, reducing need for new hotel construction
- Zipcar/Car2Go: Car-sharing services reduce individual car ownership
- Tool libraries: Community tool-sharing programs
- WeWork: Shared office spaces maximize building utilization
3. Product Life Extension
Model: Extend product lifespan through repair, refurbishment, remanufacturing, and upgrades, keeping products in use longer and delaying disposal.
Strategies:
- Repair services: Fix broken products to restore function
- Refurbishment: Restore used products to sellable condition
- Remanufacturing: Rebuild products to like-new standards
- Upgrades: Improve products with new components or software
- Maintenance programs: Preventive care extends lifespan
Examples:
- Patagonia Worn Wear: Repair program and resale of used clothing
- Apple Trade-In: Refurbish and resell used iPhones
- Caterpillar Remanufacturing: Rebuild heavy machinery to original specs
- Fairphone: Modular smartphone designed for easy repair and upgrades
4. Resource Recovery and Recycling
Model: Recover valuable materials from products at end of life and reintroduce them into production cycles, closing material loops.
Approaches:
- Take-back programs: Collect used products from customers
- Material recycling: Process waste into new raw materials
- Upcycling: Transform waste into higher-value products
- Industrial symbiosis: One company's waste becomes another's input
Examples:
- H&M Garment Collection: Take back old clothes for recycling into new textiles
- Interface Carpets: Reclaim old carpets and recycle into new products
- TerraCycle: Recycle hard-to-recycle materials (chip bags, cigarette butts)
- Kalundborg Symbiosis (Denmark): Industrial park where companies exchange waste streams
5. Circular Supplies
Model: Replace traditional resources with renewable, bio-based, or fully recyclable inputs that can safely return to nature or technical cycles.
Focus areas:
- Renewable materials: Bamboo, hemp, mycelium instead of synthetics
- Bio-based plastics: Compostable alternatives to petroleum plastics
- Recycled content: Use post-consumer recycled materials
- Circular feedstocks: Materials designed for perpetual recycling
Examples:
- Adidas x Parley: Shoes made from ocean plastic waste

✓ BMT 8 Summary: Circular Business Models
You should now understand that circular business models minimize waste and maximize resource efficiency by creating closed-loop systems where products and materials are continuously reused, contrasting sharply with linear "take-make-dispose" economy. The circular economy operates on three core principles: design out waste and pollution, keep products and materials in use through repair/refurbishment/recycling, and regenerate natural systems by returning nutrients to environment. Five main circular business models exist: product-as-a-service (leasing rather than selling), sharing platforms (maximizing asset utilization), product life extension (repair/refurbishment/remanufacturing), resource recovery and recycling (closing material loops), and circular supplies (using renewable/recyclable inputs). Benefits include environmental advantages (reduced waste, emissions, resource extraction), economic gains (cost savings, new revenue streams, innovation, competitive advantage), and social improvements (affordable access, job creation, health benefits), though challenges include high upfront investment, consumer mindset barriers, complexity, and systemic obstacles. Successful implementation requires circular design (durability, disassembly, modularity), operational changes (reverse logistics, maintenance services, remanufacturing), and business model innovation (service offerings, take-back programs, performance pricing). Real-world examples like Interface carpets, Philips lighting-as-service, Patagonia Worn Wear, and Fairphone demonstrate profitability while achieving sustainability. Understanding circular business models is increasingly critical as businesses, governments, and consumers recognize need to transition from extractive linear economy to regenerative circular systems.
