It is estimated that of the 100 billion tonnes of resources that the world uses every year, only 8.6% is cycled back into our economy: over 90% of what we take from the earth goes to waste. The linear model of extracting, using and wasting has heavy consequences on the environment, among them resource exhaustion, biodiversity loss, global warming, air pollution and plastic soup. An alternative sustainable consumption model is offered by the circular economy, wherein existing materials and products are shared, reused, repaired, and recycled as long as possible. In other words, the circular economy provides a framework for decoupling growth from material extraction. In the last decade, an increasing number of organisations have started challenging linear business models with circular ones, fostering one of the most thriving and innovative ecosystems in the impact scene. Here we mapped 280+ startups globally that are contributing to the circular economy.
