Umicore. Workers at Umicore in Brussels separate out precious metals from electronic waste.
When my battered 1969 Toyota car approached the age of 30, I decided that her body deserved to be remanufactured. After 2 months and 100 hours of work, she returned home in her original beauty. “I am so glad you finally bought a new car,” my neighbour remarked. Quality is still associated with newness not with caring; long-term use as undesirable, not resourceful.
Cycles, such as of water and nutrients, abound in nature — discards become resources for others. Yet humans continue to ‘make, use, dispose’. One-third of plastic waste globally is not collected or managed1.
There is an alternative. A ‘circular economy’ would turn goods that are at the end of their service life into resources for others, closing loops in industrial ecosystems and minimizing waste (see ‘Closing loops’). It would change economic logic because it replaces production with sufficiency: reuse what you can, recycle what cannot be reused, repair what is broken, remanufacture what cannot be repaired. A study of seven European nations found that a shift to a circular economy would reduce each nation’s greenhouse-gas emissions by up to 70% and grow its workforce by about 4% — the ultimate low-carbon economy (see go.nature.com/biecsc).
The concept grew out of the idea of substituting manpower for energy, first described 40 years ago in a report2 to the European Commission by me and Geneviève Reday-Mulvey while we were at the Battelle Research Centre in Geneva, Switzerland. The early 1970s saw rising energy prices and high unemployment. As an architect, I knew that it took more labour and fewer resources to refurbish buildings than to erect new ones. The principle is true for any stock or capital, from mobile phones to arable land and cultural heritage.
