Ressource conservation


An integral part of company policy has always been the protection of natural resources.
Substitution potentials can be discovered at different points of the value chain.
Furthermore as a reliable partner we provide an important contribution to recycling and waste management.

Secondary raw materials


Secondary raw materials can not only be used to specifically supplement absent components, but to replace natural materials such as lime, clay and sand.









Secondary raw materials
- commonly used:

- Recycled aggregates
- Coupling (by-)products from the steel mill industry
- Mineral waste from the power plant industry
- Old concrete

Secundary fuels


Meanwhile there are good reasons for replacing fossil fuels such as coal, oil or natural gas by suitable secondary fuels. Finite resources are  saved while making an active contribution to reducing CO2 emissions at the same time.

The cement rotary kiln with its high temperatures (of up to 2000 °C) and its high effeciency is the prominent option to safely recycle many materials. The resulting ashes are fully absorbed in the cement clinker and therefore needn't be deposed of separately.

Secondary fuels - commonly used:

- Used tyres
- Plastics, paper, films (solid fuels)
- Recycled liquid oils
- Sewage sludge granules
