July 2010: Production of Greener Cement to Reduce Greenhouse Gas Emissions

Each year nearly three billion tons of cement are produced globally for the construction industry and this production process contributes to 5% of the world’s annual CO2-emissions. Scientists at the Karlsruhe Institute of Technology (KIT) have invented a new type of cement production that saves energy and has the potential to cut carbon dioxide emissions approximately in half. After extensive lab research, KIT has proven that this new type of cement, Celitement, can be produced at lower temperatures (less than 300˚C vs. 1,450˚C) and with less lime than conventional cement.

Celitement GmbH, the spin-off of the four inventors, KIT, and their industrial partner Schwenk Group (Schwenk Zement KG) have invested five million euros in the construction of the pilot plant on the north campus of KIT. The groundbreaking took place on July 8, 2010 – and daily production of 100 kg is expected by spring 2011.

In addition, about 3.5 million euros for accompanying  research (e.g. material and energy balances and the sustainability of the processing chain) are provided by the Federal Ministry of Education and Research (BMBF) under the framework program “Research for Sustainable Developments.”
