Summer is vacation time. Some people are still enjoying their holidays, while others have already returned home. This is also a time when people like to “look beyond the horizon”, visiting unfamiliar and perhaps more distant countries. This is often the case in our professional environment as well.

The new pilot plant for tempered clays at the Rohrdorf cement plant successfully went into operation at the beginning of July. In the plant, raw clay is activated (“tempered”) through thermal treatment. The aim of the plant is to research tempered clays, as these can be used as a lower-CO₂ alternative to clinker, the main component of cement.

Starlinger presents technical solutions for closed-loop systems in woven plastic packaging. “Plastic packaging is the packaging of the future,” stated Harald Neumüller, CSO of Starlinger.

In recent years, the adoption of alternative fuels has become a key factor in the sustainable evolution of the lime industry. In particular, the use of biomass is emerging as an effective solution to reduce environmental impact while ensuring a more flexible and resilient energy supply.

Aerzen is significantly expanding its product portfolio in the higher-pressure range and has added innovative compressors from the standard segment for differential pressures of up to 13 bar.

The process of clinker manufacture has evolved massively over the last decades. Back in 1843 when William Aspdin invented the technical process of clinker manufacture in a rotary kiln, the production was primarily driven by the burner. With all the developments coming in the subsequent years, especially the precalciner and the external combustion chambers, the main burner (as it has been called since then) only takes over about 45% of the thermal input.
