What is the circular economy (and why it's not just recycling)?
Recycling is the last resort, not the strategy. True circularity begins much earlier: use less, use longer, put back into circulation — in the right order.
The problem with the linear model
Take, make, use, throw away: the linear model built modern abundance by offloading its costs upstream (extraction of increasingly contested raw materials) and downstream (waste, dispersal, emissions). Today it bills us twice: as environmental risk and as economic risk — companies that depend on volatile virgin materials and long supply chains know this well. The circular economy is the systemic response: designing flows so that materials stay in use and value is not lost.
The hierarchy that matters
Circular strategies follow a precise order of value, and recycling sits at the bottom. First: refuse and reduce (the best waste is the waste never created). Then: reuse, repair, regenerate (keeping products alive preserves almost all of their value). Only then: recycle (recovering the material, but losing the product's value). Each higher step preserves more value with less energy — which is why judging a company's circularity by waste sorting alone is like judging a diet by what's in the bin.
The secret lies in design
The decisive part of circularity happens before the product exists: at the design stage, the vast majority of a product's environmental impact is determined. An object designed to be disassembled can be repaired; one that is glued together gets thrown away. A single-component material can be recycled; a multi-layer composite almost never can. This is why the sector is looking for designers and engineers with a circular mindset: circularity is not added at the end — it is designed in from the start.
Business models, not just materials
Mature circularity also changes the way things are sold: product as a service (you pay for use, the manufacturer has every incentive to make it last), reuse and refurbishment platforms, returns that become resources, industrial symbiosis — one company's waste as another's raw material. These models align incentives: when a manufacturer profits from durability, quality becomes good business again.
Where your talent comes in
The circular economy looks for hybrid profiles: people who can read material flows, design for durability, build return supply chains, and measure impact. On Simbial, this world has its own role — Impact Circular Economy Specialist — and the pills that follow build the foundations: design, supply chains, measurement, projects. Circularity is the ideal field for those who love solving system puzzles.
Frequently asked questions
What is the difference between circular economy and recycling?
Recycling recovers material from waste and is the last strategy in the hierarchy. Circularity starts earlier: reduce, extend lifespan, reuse, repair — preserving the value of products, not just of materials.
Why is design central to circularity?
Because most of a product's impact is determined at the design stage: disassembly, materials, durability, repairability. Circularity is designed at the beginning, not added at the end.
What is industrial symbiosis?
The waste of one company becomes the raw material of another: flows of materials, heat, or water shared between different activities. One of the circular models with the greatest systemic impact.
