Asked about the “major challenges” of his role advising the Government, Prof Mackay told a Department of Energy and Climate Change newsletter: “One difficult challenge is the way in which economic activity and growth currently is coupled to buying lots of stuff and then throwing it away.
“When a fridge, clothes-washer, or microwave develops a fault we throw it away instead of repairing it. Car manufacturers love us to buy a new car every few years.”
Prof MacKay, who wrote the book “Sustainable Energy – without the hot air” and teaches at Cambridge University, claimed that products could be taken apart at the end of their lifetimes so that parts can be recycled.
Generally known as the “scrap metal market”.
