Vecoplan supplies state-of-the-art shredding technology
to Sanit-Trans
Secondary fuels can reduce the costs involved in the energy-intensive production of cement by replacing a large proportion of expensive primary fuels. Sanit-Trans also achieves this by processing various waste fractions into high-quality, refuse-derived fuels (RDF). Vecoplan supplied the shredding technology for a modern processing line during the Covid-19 pandemic – and the outcome? Installation and commissioning functioned very smoothly. [Photo: Vecoplan AG]

BEUMER Group: U-shape conveyor
 
The U-shape conveyor allows the implementation of narrower curve radii than a troughed belt conveyor and higher mass flows than a pipe conveyor. At the same time and contrary to the troughed belt conveyor, it protects the material conveyed from environmental influence and the environment from material loss and emissions. Thus this u-shaped conveying solution has proven to be an ideal alternative in the cement industry as well as in port terminals if high capacity is required with little space available.

thyssenkrupp, Holcim and TU Berlin kick off research project
on CO2 reduction
The cement industry is working on reducing CO2 emissions in a number of ways. Why? Because even with the sole use of renewable energies, the raw materials used in cement production result in CO2 being released and emitted to the atmosphere. thyssenkrupp Uhde, Holcim and the Technische Universität Berlin have therefore partnered up in a joint project to investigate the use of a novel amine scrubbing technology for carbon capture.
