InterCal Slovenija<\/h2>\n

\nIn 2019 InterCal Slovenija took over the production and quarry of Apnenec d.o.o. for amplifying its product portfolio and securing its long term raw material supply.<\/p>\n<\/div>

Calcitic and Dolomitic Limestone from Slovenia and Croatia<\/h2>\n

In Zagorje, Slovenia, 40 km east of Ljubljana, lime has been burned for 200 years. Here we produce calcitic and dolomitic limes for ecological and technological applications as well as hydrated lime and putty lime. The Sira\u010d lime plant in Croatia specialises in the production of dolomitic limes, which are used as high-quality admixtures for various steelmaking processes. As hydrated lime, dolomitic lime is also characterised by very good processability for building materials.<\/p>\n<\/div><\/div><\/div>

Great diversity for Central and Eastern Europe<\/h2>\n

With five locations in the south of Austria, in central Slovenia and in Croatia, we can cover a large geographical area. With our calcitic and dolomitic limes, we can also serve a wide range of customers, from agriculture and forestry to the iron and steel industry, the chemical industry, the paper industry and the building materials industry.<\/p>\n<\/div><\/div><\/div>

Intercal expands<\/h2>\n

As demand for lime products from Sirac exceeds the current kiln capacity, a second kiln will go into operation this year.
\nTwo factors are crucial here:
\n1.) The worldwide bottleneck in the production of refractory products. Among those affected is the steel industry, which is aware of the issue and is focusing its attention increasingly on the lining (firebricks) of their furnaces. Dolomitic lime from Sirac is well suited for this purpose as it protects the lining of the furnaces (subject to technical processes), prolonging necessary inspection intervals and thus reducing costs.
\n2.) An entirely different topic, but no less important for the lime plant in Sirac, is the increased promotion of agriculture in the CEE region, which leads to an increased demand for fertilizer lime.<\/p>\n<\/div><\/div><\/div>
