Medium-sized instead of mediocre
Welcome to Calcis, a medium-sized group of companies that specializes in one of mankind's most fascinating raw materials: lime. This amazing mineral with its many different forms was, is and remains the mother of all materials. From the Stone Age to the age of communication, from the Egyptian pyramids to the space shuttle, from ancient Roman lime kilns to modern GGR shaft kilns: Kalköfen has accompanied the history of human civilization from day one.
The imaginative use of this unique rock is a tradition to which we commit ourselves anew every day. With versatile products made from high-quality lime and with intelligent solutions in the interests of our customers, we combine expertise and commitment to form a medium-sized umbrella brand that unites 3 productive locations to form a full-range industrial supplier.
