Poul Erik Beck founds Silbeko, later Silkeborg Kvartssand A / S. Since the beginning of the 60's, Poul Erik Beck has overseen the family business and haulage business Jens Konrad. The company owns several gravel pits, including the pit in Addit, which contains a unique reserve of "white" sand. The sand is of such a high quality that it can be used as an ingredient in industry. But sand is not just sand. Different customers and different industries place different demands on the composition of the material, and Poul Erik Beck sees potential in creating a new type of silica sand-based products. The idea is to separate the raw sand, wash and dry it and put together the special sand fractions that the industry demands.
In collaboration with the Danish Technological Institute and a small group of employees, Poul Erik Beck is working intensively to develop a product range that meets the specifications of the Danish foundry industry.
