From liner economy to circular economy

This circular economy looks at all the options across the chain to use as few resources as possible in the first place, keep resources in circulation for as long as possible, extract the maximum value from them while in use, then recover and regenerate products at the end of service life. There are three principles for circular economy: Reduce, Reuse and Recycle.

In a circular economy we would ideally like to produce no waste at all. In our current society, however, some goods or resources inevitably face waste because they cannot be recycled and are linear consumer goods. In the case of linear consumer goods we can only do our best to make the best use of them.（fig.1）

I found a good example of transforming a linear economy into a circular economy (but maybe it shouldn’t be suitable for large-scale use yet)

Oyster shell is a consumer product in the linear economy, which is discarded as hazardous waste in the fishing industry and the collection, transport and disposal of this waste causes even greater harm to the environment. The main component of oyster shells is calcium carbonate, which is a major component of cement and concrete, at 95%, and Markos Georgiou began collecting oyster shells from restaurants and turning them into useful and valuable ceramic products through design research.
