Mineral Resources – A Basis for Life

How many kilos of rocks does each one of us need per hour?

How many kilos of rocks does each one of us need per hour?
The Federal Mineral Resources Association (Bundesverband Mineralische Rohstoffe, MIRO) found the answer to that question in an interesting and entertaining film.

In actual fact, mineral resources – extracted from excavation lakes, gravel pits and stone quarries – are essential for our living standard. Crushed rock, sand, grit, gravel and granite accompany us throughout our lives – from the baptismal font to the tombstone – and amount to 1 kilogramme per hour and per German citizen.

For example, 216,000 tonnes of sand, gravel and grit are required for one kilometre of Autobahn. A total of 63,000 cubic metres of concrete – and concrete consists of 80% rock and sand – was incorporated into the Elbphilharmonie with water and cement. For one kilometre of railway track you need 35,000 tonnes of crushed rock. Around 270,000 cubic metres of concrete will help the Stuttgart – Ulm rail project along.
