Our Group of Companies

GEBR. ZIEGLOWSKI, INTERBIMS, KLANZ

The group of companies GEBR. ZIEGLOWSKI, iNTERBiMS, KLANZ

KLANZ is integrated into a solid and ownermanaged medium-sized group of companies together with our affiliates iNTERBiMS and GEBR. ZIEGLOWSKI.  


We own the mines and therefore the valuable raw material deposits ourselves. This  ownership, combined with our expertise as a manufacturer, developer and processor of the extracted raw materials, makes us an efficient and flexible high-performance supplier for the green industry.  


The main components of our plant substrates are washed pumice, zeolite and lava. These three mixing components complement each other perfectly and are an ideal rooting space for all plants thanks to the selected grain size composition. Their excellent nutrient storage capacity and good pH buffering make these mineral substrates excellent planting media.  


A range of additional mixing components are also available to meet customer requirements according to the customer's wishes and the needs of the different crops and plant species. Whether special fertilizers for a needsspecific nutrient supply or organic mixing components: There are many options and combinations possible.
