Every year, the world adds 11.2 billion tonnes of solid waste to our combined rubbish pile, according to UN figures – the decaying organic parts of which contribute five per cent of global greenhouse gas emissions. We need to find a way to reduce waste, and the answer could be moving to a circular economy, which seeks to design out wastage by making use of byproducts and reusing materials. “The circular economy is an excellent way to deal with many of the major crises that we are facing,” says Anne Velenturf, a circular economy researcher at the University of Leeds. “Producing stuff takes a lot of energy, and if we make better use of our products then we also save much of the carbon embodied in them.”
