What is a circular economy?
Since the industrial revolution started, the amount of waste in the environment has constantly increased. This is because our economies have used a take»make»consume»dispose model – a linear approach which assumes that resources are abundant, easily available and easy and harmless to dispose of – which they aren’t.
The aim of a circular economy is to create a loop where all outputs of the economy are not wasted but recycled back into production. This means re-using, repairing, refurbishing and recycling existing resources, materials and products. What used to be regarded as ‘waste’ can be turned into a resource. All resources will be managed more efficiently throughout their life cycle.
In a circular economy there are two types of material flows:
- biological resources – designed to reenter the biosphere safely
- technical resources – designed to circulate continually without entering the biosphere
Using resources more efficiently will also bring new growth and job opportunities. Better eco-design, waste prevention and reuse can bring net savings for businesses while also reducing total annual greenhouse gas emissions. The economic benefit of transitioning to this new business model is estimated to be worth more than one trillion dollar in materials savings.
A circular economy would internalise external costs by recycling resources and therefore eliminating waste disposal and environmental degradation.
Design for sustainability
In a circular economy the design of products, services and business systems would take on a new dimension. The way in which a product would be retrieved, dismantled and reused would need to be designed into the product from the beginning. This feedback would cause the design to evolve organically, improving in both effectiveness and efficiency over time.
This type of design thinking would involve economy-wide collaboration and co-operation potentially providing significant synergies and efficiencies.

The following case studies were provided by the World Economic Forum.
Ricoh — Resource recirculation in the inner loop.
Ricoh, provider of managed document services, production printing, office solutions and IT services, established the Comet Circle™ in 1994 as a catalyst for reducing environmental impact. It embodies the belief that all product parts, for example for copiers and printers, should be designed and manufactured such that they can be recycled or reused. Read more about Ricoh»
Philips — Lighting as a service.
Philips has a track record in the collection and recycling of lamps. For example, in the EU, Philips has a stake in 22 collection and service organizations that collect 40% of all mercury-containing lamps put on the market and with a recycling rate greater than 95%. Read more about Philips»
