Circular supply chain: circular logistics and sustainable supply chains
A circular supply chain is a supply chain in which products, materials and raw materials remain in circulation for as long as possible. Instead of the traditional model, where a product is discarded after use, goods are recovered, repaired, reused or recycled. The circular chain is self-contained: what marks the end of one life cycle forms the start of a new one.
Linear versus circular: what is the difference?
Most supply chains are still structured linearly. Raw materials are processed into a product, the product is sold and discarded after use. Whilst this model may be efficient in the short term, it generates a great deal of waste and remains dependent on a constant supply of new raw materials.
A circular supply chain breaks this pattern by organising the return flow just as effectively as the outbound flow. Returned products are assessed, sorted and, where possible, reused. This reduces waste, lowers the need for new raw materials and reduces the environmental footprint of the entire chain.
| Characteristic | Linear chain | Circular chain |
|---|---|---|
| Raw material use | High and usually single-use | Lower, with reuse as the starting point |
| Return flow | Not organised, or only to a very limited extent | An integral part of the supply chain |
| End of life | The product becomes waste | The product serves as input for a new cycle |
| CO₂ emissions | Relatively high per product | Lower through the reuse of products and materials |
| Cost model | Lower start-up costs and higher disposal costs | Higher start-up costs and lower raw material costs |
The three pillars of a circular supply chain
A circular supply chain is not created by a single, isolated intervention. It requires structural choices at three levels which, together, close the loop.
1. Product design focused on reuse
Circularity begins with the design of a product. Products that are easy to dismantle, contain replaceable parts and are made from recyclable materials are better suited to a circular supply chain. Retailers and manufacturers wishing to make their product ranges more sustainable must therefore take reuse, repair and recycling into account right from the design phase.
2. Returns logistics as a core process
The physical returns flow forms the heart of a circular supply chain. Goods must be collected efficiently, transported to a processing centre and assessed there for their condition. They are then sent on for reuse, refurbishment, repair, parts recovery or recycling.
A logistics partner that integrates return flows into day-to-day operations makes circularity a practical reality. Furthermore, by combining returns with existing delivery routes, the number of empty kilometres can be reduced.
3. Data tracking throughout the entire supply chain
Circularity only works when it is known where every product is located and what condition it is in. Track-and-trace systems monitor goods from the initial delivery right through to any return shipment. This data supports decisions on reuse and enables reporting on the environmental impact of the supply chain.
Circular supply chain in practice: large goods
A circular approach is particularly relevant for sectors such as large electrical goods, furniture and bicycles. These products often contain valuable materials and components, whilst their transport and processing require specialist knowledge.
A washing machine returned to a retailer, for example, can follow various routes. The appliance can be sent back to the manufacturer for refurbishment, channelled into a second-hand market, or dismantled to recover usable parts and materials.
Which route is most suitable depends on the condition of the product, the repair costs, the residual value and the agreements between the parties involved in the supply chain.
The role of returns logistics
Returns logistics ensures that used, damaged or discarded goods are reintroduced into the supply chain. Without a well-organised returns flow, products and materials cannot be recovered efficiently.
For large goods, reverse logistics involves more than just collecting a product. The logistics partner can also handle registration, visual inspection, sorting and transport to the correct processing point. This ensures that every return consignment is directed to the appropriate next step as quickly as possible.
Benefits of a circular supply chain
The benefits of a circular supply chain are both environmental and commercial. Companies that organise their circular supply chain effectively benefit in several ways:
- Lower raw material and procurement costs through the reuse of materials and components
- Reduced waste disposal and lower associated costs
- A lower environmental footprint of products and logistics processes
- A stronger position in tenders and bids with sustainability requirements
- Greater insight into product flows through systematic recording and data tracking
- Higher customer satisfaction among consumers who consciously choose a sustainable returns policy
Circular logistics within the last mile
Within the last mile, the outbound and return flows converge. A vehicle delivering a new product can simultaneously collect an old or damaged product. This reduces the number of separate journeys required and ensures vehicles are utilised more efficiently.
Planning deliveries and returns from a single system creates a closed-loop logistics flow. This makes it possible to assess products more quickly, re-deploy them and transport them to the correct processing location.
