ELIMINATING CARBON EMISSIONS
OUR PARTNERSHIP WITH EBERHARD
TWO SWISS FAMILY BUSINESSES
JOINING FORCES TO PROTECT OUR CLIMATE
Two SMEs are joining forces to actively reduce the amount of CO2 in the air with an innovative climate protection project.
Through their cooperation, the two traditional Swiss family businesses Eberhard Unternehmungen and Kuhn Rikon are making an important contribution to environmental protection. Thanks to an innovative process, CO2 can, for the first time in Switzerland, be actively taken out of circulation and permanently sequestered in concrete. CO2 storage in concrete takes place in a concrete plant in Switzerland and is verified by an external company
IN CONVERSATION WITH PATRICK EBERHARD, BOARD MEMBER AND OWNER
„We are proud to be able to support the family-owned company Eberhard in its ground-breaking sustainability project. Through this cooperation, we are taking an important step towards protecting our climate and hope that this commitment also inspires other companies to take similar action.“
Tobias Gerfin, Kuhn Rikon CEO
SUSTAINABLE CONCRETE
Sustainable concrete with a low carbon footprint
In urban mining, the building stock of a city is regarded as a raw material store for new houses. Circular concrete (that is, concrete composed largely of recycled materials) is sustainably produced from construction rubble in a circular economy and has equivalent material properties to new concrete. Thanks to the innovative processing technology, the circular concrete can be used for all components of new houses. With this processing technology, CO2 is also sequestered in the processed sand and gravel grains.
1. Old concrete is brought to the processing plant, broken up and sorted.
2. The sorted concrete fragments replace the sand and gravel in the concrete as a secondary raw material.
3. The secondary raw material is treated with pure CO2. A chemical reaction occurs in the pores of the concrete granules, producing natural limestone. The CO2 then remains permanently sequestered in the treated concrete granulate.
4. The carbon-containing concrete granules are mixed with cement and water in the concrete plant to create circular concrete.
