The circular economy is typically seen as the progressive alternative to our wasteful linear economy, where raw materials are used to make the products that feed today’s rampant consumerist hunger, which are then thrown away. The idea of the circular economy only took off in the 1980s, but this doesn’t mean that the practices at the core of a circular economy, such as repairing, recycling, refurbishing, or repurposing, are equally novel. All of these strategies have the aim of keeping materials in use – whether as objects or as their raw components – for as long as possible. And all are hardly revolutionary.
