He deposited in the floodplain on the Rhine, in Northern and Eastern Germany and in the Bavarian foothills of the Alps: The otherwise resource-poor Germany has massive Sand; and unnoticed, the tiny grains between 0.063 and 2 millimeters in size the everyday life of the consumer. Sand is in glass, auto headlights, smart phone Displays, cosmetics and even toothpaste. It is used to filter water, facades radiate and to put the brakes on trains better.

“Mathematically, every German consumes a Kilo of Rock per hour,” says Bert Vulpius, managing Director of the entrepreneurs Association of Mineral building materials. Per year the to be nearly nine tons.

But Sand and coarser gravel are scarce; especially in the construction, for concrete, brick, Asphalt and mortar are needed. In the real-estate boom that has now continued for almost ten years, has increased the demand for the raw material rapidly. The construction of warns and engineering industry from Sand deficiency. He verteure concrete and driving the prices high and the Rents in the cities.

In the case of certain varieties for the concrete production, there are “acute problems” in the delivery, said the Central Association of German construction industry (ZDB). The result were increases in the hefty price: the concrete was more expensive in Berlin and Brandenburg in the past nine months to around ten percent. Also in Hamburg, Cologne and Düsseldorf, there is always limited time constraints.

In freshly mixed concrete, for example, it will be tight. In this transport concrete, there are problems in the supply of aggregate materials such as Sand or gravel, says Vulpius, especially in urban areas, where deposits were missing. Especially in the densely populated southern Germany, it is becoming harder and harder to get land for the extraction of raw materials.

Many do not Happen-degradable

While Germany has rich natural Deposits of Sand, says the German Federal Institute for Geosciences and natural resources (BGR). The approximately 2000 Sand and gravel pits in this country to win around 240 million tons of construction sand and gravel per year. A large part of the Deposits, but in conservation areas, residential and commercial areas, roads and rails, and thus not biodegradable, so the authority. And farmers want to sell in times of rising prices, no Fields.

At the same time, the approval of new mining areas is lengthy. By the request of individual companies up to the start of construction of the pits for ten years or more passed by often Sylvia Reyer-Rohde, a Board member of the Federal chamber of engineers says. In plan-approval procedures, all the parties Concerned such as local residents, environmentalists and farmers could present concerns. And the raw material was in the unpopular. “No district in his circle like a sand pit.”

In East Germany, for instance, has opened in the building boom following reunification, led to a series of pits. However, after 30 years, many are exhausted. To develop “recovery sites is difficult and permits to take due to stricter environmental laws getting longer and longer,” he Vulpius. The number of mining sites in Germany is decreasing so for twenty years.

The result of the sand shortage, construction delays, and in extreme cases a standstill, warns the Federal chamber of engineers. “In Berlin, for example, you have to wait mixtures for 14 days on certain fine concrete.” Sand and gravel would have been more expensive to 2018 by around five percent.

Also, imports are hardly a solution to the shortage, said Vulpius. Because of the heavy load of sand makes transport by Truck is expensive. “From a distance of about 50 kilometers, which is uneconomical.”

the Sand shortage because Germany is not alone. Worldwide reserves dwindle, for instance, in the boom of emerging countries in Asia. “Sand and gravel are the most mined resource in the world,” writes Aurora Torres, a scientist at the German centre for integrative biodiversity research in Leipzig. In Asia, for example, Sand will be mined, often illegally on beaches or in rivers. The destroy Ecosystems with dire consequences – for example, because coastlines no longer protected due to soil Erosion from Storms and Tsunamis.

With the world’s growing cities, the demand for Sand and gravel is far greater than any other building material, says the consulting firm A. T. Kearney. “The sand industry is set to remain for a long time under pressure.” In India and Malaysia extreme consequences were already There, the sand shortage will lead to construction projects.
