Understanding the Sand Shortage: Why We’re Running Out of Sand
The world uses 50 billion metric tons of sand annually.
Sand is a key ingredient in all concrete and glass production.
There are already ongoing reports of a mafia-style black market for sand.
The world is in crisis yet again. This time around, it’s a sand shortage.
The most-extracted solid material in the world, and second-most used global resource behind water, sand is an unregulated material used extensively in nearly every construction project on Earth. And with 50 billion metric tons consumed annually—enough to build an 88-foot-tall, 88-foot-wide wall around the world—our sand depletion is on the rise, and a completely unregulated rise at that.
Naturally occurring over thousands of years—if not hundreds of thousands of years, most sand originates in the mountains and forms as rivers bring it downstream toward oceans. Sure, head to beaches across the world to feel the sand between your toes, but sand does more than delight beachgoers and build cities. Sand also performs key environmental roles; it is a major factor in protecting from storm surges, ensuring healthy natural habitats for a variety of species, and protecting against erosion.
And again, what you consider to be merely an economic issue is exactly where you seem to be missing the point.
Quarrying is environmentally destructive. It has contamination and pollution issues. It carries health issues. As well as the costly logistics of transporting bulk around the planet. Governments these days no longer wish any company, large or small, to go around tearing rock, in any form - pre ground or otherwise -out of the ground. So your next problem would be sourcing the base materials for your manufactured product legally.
Economically, even if you did manage to quarry,crush,sieve,grade and mix your sand for lets say £1000 a ton. What architect on the planet would specify the use of such an environmentally unfriendly and costly material and what construction company in the world would pay such a price?
Architects are already specifying more sustainable materials and construction techniques are changeing, but at present, people are still destroying the planet and killing each other for sand ! That’s the current economic situation.
