Kalkfabrik Netstal AG

KFN is the only producer of quicklime products in Switzerland. The natural limestone that we have been mining for more than a century at the Elggis mountain in the Swiss canton of Glarus is 98 % pure calcium carbonate.
 

Thanks to a geological oddity, in the Swiss canton of Glarus the oldest sedimented lime layers are to be found on the surface. They are the ones with the largest degree of purity – a considerable success factor of our KFN quicklime products. Each year we produce roughly 90,000 metric tons of them for our customers coming from traditional as well as nascent industries.
