Circular Economy: The Ultimate Form Of Sustainability

Topic: Sustainable Design
Circular economy: the ultimate form of sustainability

Sustainability and circular economy are terms we’re hearing a lot these days, to the point that we can start calling them design trends...but what do they really mean?

The concept of sustainability has a number of slightly different meanings:

  • being respectful of the planet without damaging it with waste or pollutants
  • giving natural resources the time to regenerate between uses without exploiting them too fast
  • treating every person with respect without denying well-being to anybody

and more…

In general, sustainability means keeping a long-term view that aims at preserving our planet and its resources so that life (for both us humans and other species) can continue in the future in a happy balance.

Looking at us and our current way of living, it’s easy to realize that we’re not walking along a sustainable path. We use a lot of resources, often don’t give them the time to regenerate and produce a lot of waste.

But this is not because we are bad!

In fact, it is mostly due to the way we’ve been operating so far. The majority of the things we use has been designed with a linear flow in mind. Products are meant to be made, used and then tossed at some point, in a take-make-dispose cycle. And what happens after a product has been disposed was for long time not a subject of interest.
Today, plastic-invaded oceans and overflowing landfills are here to prove that this is not a sustainable path and something needs to change.

So what to do?

What needs to change first of all is the design approach.
For the first time designers need to consider upfront what will happen when the product will be tossed and how its materials will be transformed, reused and made useful again, in a virtually never-ending cycle.

In short words, circular economy is the answer.

Which materials for a circular economy?

Designing a product with a circular flow in mind requires extreme attention in the selection of every single component and material. In a circular economy, the same materials will circulate in the system over and over again, so it’s essential to choose them carefully.

All the materials we use today can be assessed and improved in terms of resources used to produce them, ethical and social aspects of their production, use of chemicals etc. And the resulting materials will be something that can sustainably circulate in the system.
 
In particular, the way a material cycles into the system can be either biological or technical.
All biodegradable materials (like wood, paper etc…) will go back into the environment after use – in a biological cycle. The more compostable materials we use, the more we’ll be able to fertilize the soil, creating value out of waste.

Materials like plastic or metals instead, will go through a technical cycle, i.e. they’ll be transformed (physically or chemically) to be reused beyond the life cycle of a single product.

Above all, a circular and sustainable design approach suggests to

  • source materials that come as waste in another production process
  • make sure materials are extracted respecting the planet (when sourcing new ones).

Will products become services?

All this discussion about circular economy has raised a very interesting question around the topic of “ownership”.

If we think about it, what we really need most of the times is a certain functionality more than an object. These are some questions that made me think:

  • Do we need to own a car or do we just need to go from A to B?
  • Do we need to own furniture or do we just need a (beautifully and functionally) furnished home?
  • Do we need to own a washing machine or do we just need to wash clothes at home?

and the list could continue...

In a circular economy scenario, an alternative to owning objects would be to “borrow” them from the manufacturers and pay a service licence for their use.

This approach would actually benefit both manufacturers and customers.
Manufacturers would still own their products (and all their expensive components). They’d also maintain broader and better control over them, allowing for more efficient maintenance.
On the other side, customers would only pay for what they actually use without having to care about maintenance and repairs. This would also probably reduce waste at its source as manufacturers would be motivated to make products that last longer instead of being driven by “selling more products” as they are now.

A new sustainable living scheme 

Overall, the idea of circular economy brings huge changes on both materials and processes.

In a licencing-instead-of-owning scenario, products are designed to be disassembled and regenerated instead of being tossed.

And for what concerns materials, all biodegradable parts can go back to the soil and feed the agriculture, while non-biodegradable materials are reused in the new generation of products.

To make this a fully sustainable living scheme, transport methods are also an important part of the game and need to be based on renewable resources.

 
Circular economy is definitely a long-run objective. The most ambitious part of it is that – in order to switch to circular economy – there need to be many (virtually all) companies that work in the same direction.
Not an easy task for sure. But – with the current level of knowledge and technology – we’re now having this amazing opportunity at our fingertips. We can truly redesign our future for the better!

Some companies are already moving in this direction (think about IKEA's test buy-back program for which they're "lending" sofas in the Japanese market instead of selling them).
But this may become just normal in the future!

What do you think? I honestly get really excited when I think at where this could bring us!
