A simple way to use less sand would be to reuse buildings instead of demolishing and “redeveloping” them. Here in Bristol, for example, the recent construction of a hospital involved knocking down about £60 million worth of buildings that were less than 20 years old, some less than 10 years old. Reusing them would have saved a great deal of sand and carbon dioxide emissions, not to mention money.
