KFN News

Since 2012, the Kalkfabrik Netstal AG is certified for the production of lime products for food. Since that date, the high-quality calcium oxide and calcium hydroxide products of Netstal can be purchased as guaranteed food safe. The certification was a logic consequence of the high purity of KFN lime, known for many years.

In the past years, thanks to the extraordinary purity of the KFN lime products, it has been possible to find more customers in the food, animal feed and pharmaceutical sectors. To guarantee a constant hygiene in the lime production to these customers, in 2011 the executive board decided to apply for the certification according to ISO 22000. The following year this intention has been successfully implemented: since 2012 KFN disposes of the respective certificate. In the meanwhile, the global customers’ demands have increased so much, that for the next deadline an extension to FSSC 22000* is sought.

Soil treatment with lime has been known since ancient times. It was technically developed in the 1950s to consolidate the underfloor of motorways, railway track installations and airfields. This soil treatment could spread quite widely, as hereto only simple operations are needed and it is therefore affordable and very effective. Thanks to the soil improvement with lime, soils that are otherwise useless become good installable construction materials. Soil replacement as well as difficulties in finding a landfill are avoided. A standstill at the construction site in case of bad weather can be prevented with a soil treatment with lime and in this way, a continuous building implementation will be reached.
