The beneficial filter sand used by water treatment plants is a good example of sand that is increasingly being recycled. Its availability is geographically limited, making transportation costs high, but by recycling the sand directly on site, the environmental impact and costs are significantly reduced.

The filter sand can be recycled with the help of screen and washing. By washing the sand, the sand settles and fine particles with contaminants such as algae form one fraction while clean sand forms another fraction that can be reused to its full potential.

Sand is also one of the most widely used materials in the construction industry as it is a common component in mixing materials such as cement and concrete. Today, we are working on several different solutions for recycling sand because sand is actually a finite resource that nature does not produce anew. Landfilling sand is often a worse option than recycling it on site as it involves high costs for transportation, landfill fees and the purchase of new sand.
