In 2016, together with Dr Lutz Krakow, we are starting a new series of articles on clay potential in Germany. We spoke to Dr. Lutz Krakow about the findings gained regarding the use of waste materials and give an outlook on the new series.

Zi Brick and Tile Industry International has reported on mineral waste and the possibilities for its application in the clay brick and roofing tile industry in twelve articles from issue Zi 1-2/2012 to Zi 4/2015. Have we now covered the most important types of waste or would it be possible to go on and on?
