Lime is one of Wietersdorfer’s five Business Segments
This segment comprises:
• InterCal Austria, headquartered in Klagenfurt with a plant in Peggau
• InterCal Croatia d.o.o. in Sirac and Ličko Lešće, Croatia and
• InterCal Slovenija d.o.o. in Zagorje and Zidani Most, Slovenia
Limestone has been excavated near today´s INTERCAL plants since the nineteenth century. Lime production in Ličko Lešće began in 1955 where the new kiln was erected in 1980. The orginal two kilns in Sirač were erected in 1981. The decision to switch from calcitic to dolomitic limestone was met in 1995, so new excavation sites have been developed. Since 2004, a further Maerz PFR kiln has been running in Sirač.
