2050 is a magic year
Dear Readers, 2050 is a magic year – a wealth of roadmaps postulate a carbon neutral industry by 2050, such as the iron and steel, cement or energy industries. This goal is necessary to keep global warming below 2 °C compared to pre-industrial levels. The latest UN climate report has attested that the world is steering towards global warming of 2.7 °C by the year 2100. This means it is high time to really work on the climate targets. This is only possible if CO2 emissions are drastically reduced. A number of solutions are now conceivable, at least on paper. The building materials industry, like the EU, has drawn up roadmaps up to 2050 (or 2045). How can these be implemented? Is it realistic to achieve them by the set date? And how do we achieve a global CO2 reduction? Read the exciting article “From carbon neutrality roadmaps to reality” by Dr. Joachim Harder, OneStone Consulting starting on page 30.
In our Cover Story starting on page 40 under the topic “Every crusher needs an upgrade from time to time” you can read how existing crushers can be given a longer service life and higher performance by optimizing the rotor. Even obsolete machines can be given a new lease of life and take on new tasks.
The article starting on page 42 by Prof. Dipl.-Ing. Peter Hilgraf and Dipl.-Ing. Marieke Moka of Claudius Peters shows how pneumatic test systems can be scaled up to industrial systems. The developed process is exemplified using two bulk materials, sawdust and limestone powder, with very different pneumatic conveying behavior.
Many other articles show the latest developments and current projects in the cement industry – I hope you enjoy reading them
