The mining of sand, a non-renewable resource

The inland resources of sand from rivers and lakes are not sufficient to meet the ever increasing demand and the existence of river ecosystems is threatened in a number of locations. In addition, the sand that is found in most deserts is paradoxically unsuitable for concrete and land reclaiming, as the wind erosion process forms round grains that do not bind well.

Recycling Limestone into Limestone sand has demonstrated qualities similar to natural sand, with no loss of strength. Using larger particles of crushed Limestone to produce concrete can reduce CO 2 emissions by up to 18%, and studies have shown recycled Limestone can be used for beach replenishment, both reducing shoreline damage by sand extraction while also reducing the amount of Limestone that goes to landfill.
