The sandcastle economy: How to recycle a building

The sandcastle economy: how to recycle a building

nature video published this video item, entitled “The sandcastle economy: How to recycle a building” – below is their description.

The world is running out of sand. Is circular thinking the solution?

Sand is everywhere in cities: it’s in the pillars of skyscrapers, the surfaces of roads and the walls of our homes. But sand — specifically river and beach sand needed for building — is running out, and without it the construction industry faces a crisis.

In this video we explore how a fresh framework for thinking about construction and the economy could help to combat the sand crisis and preserve the value of materials for decades to come. A circular model would mean less sand ending up in landfill, less energy wasted during construction and a more sustainable industry that benefits businesses and the planet.

This economic transformation will require collaboration between industry, government and academia — if we are to sustain our sandcastle cities into the future.
