Raw materials availability


Dear readers

The discussions about the future energy supply are accompanied, e.g., by the question of the future availability of the raw material gypsum, which is used both as a natural raw material and in the form of synthetically produced raw material – gypsum from flue gas desulfurization plants (FGD gypsum) as a byproduct of coal-fired power generation – in many areas of everyday life.

Starting on p. 46, Dr. Joachim Harder gives an overview of how the global demand for gypsum will change in the coming years and what role the production of natural or synthetic gypsum, the processing of phosphogypsum and also gypsum recycling will play in meeting this demand. Another technical article from the Thuringian Innovation Centre for Recyclables – ThIWert – at Nordhausen University, starting on p. 58, is about innovative research approaches to gypsum recycling – a way of closing the gap in the availability of gypsum raw materials for industry when FGD gypsum will no longer be available with the end of coal-fired power generation.

A technical article by Martin Engineering, starting on p. 38, deals with so-called conveyor rules of thumb, which should be observed, e.g., for the manufacture of a safe and productive conveyor system.

In addition, you will find other interesting articles as well as reports and announcements about events in the sections FOLLOW UPS (from p. 6) and FOCUS INDUSTRY (from p. 22).

Wishing you enjoyable reading
