Sand is a critical ingredient for many of the materials that we take for granted concrete, glass and asphalt. Sand and coarse aggregates form the backbone of the modern world and also, through land reclamation, the ground on which we live. A growing global population increasingly living in cities has led to a spiralling rise in the extraction of sand and aggregates, with serious environmental.
