| | The future of calcined clay by 2035 and 2050 |  |
|
| The market for clay calcination is booming. However, up to now the production is not more than 0.05% of the global cement production, although it has been projected that by 2050 a global market share of 8% could be achieved. Is this still realistic? What are the main prospects and existing market barriers? Answers to these questions and more information is given in the following article.

| | FGD gypsum can largely be replaced by gypsum and anhydrite stone | |
|
| A current study by the Federal Institute for Geosciences and Natural Resources (BGR) initially shows bottlenecks in the supply of gypsum raw materials. For some time now, manufacturers’ associations have been pointing out that the phasing out of coal-fired power generation could lead to a shortfall in the supply of gypsum raw materials. The potential of gypsum recycling is currently insufficient and cannot be fully exploited due to the lack of a legal basis.

| | Proven wear protection concepts for long service life. Many minerals put a considerable strain on the components in bulk materials systems as they are very abrasive.
Coperion masters these challenges with innovative wear protection concepts, e.g. DUROPROTECT®, that were developed based on the results of comprehensive studies.
They have proven their effectiveness in practical applications with a high degree of availability many times over.

| | Potentials of material and energy recovery of ETICS waste with EPS in the cement plant | |
|
| A large-scale test has shown that ETICS waste with HBCD-containing EPS can be materially and energetically recovered under controlled conditions without negative effects on emissions, operation and clinker quality - a possible building block for a broader raw materials strategy.
