History of the Grodan Group
In 1949, the ROCKWOOL Group opened a manufacturing plant in IJmuiden, the Netherlands, relocating this facility to Roermond in 1968. One year later, the ROCKWOOL Group in Denmark founded the Grodan Group to focus on production of stone wool substrate for the horticulture sector. In 1979, the Grodan Group established itself in the Netherlands at the ROCKWOOL complex in Roermond.
Around the new Millennium, the Grodan Group profiled itself more as a supplier of total solutions: a combination of clean and manageable substrate, advising and support services. As part of this, the concepts of sustainable business became one of the Group’s most important concerns. Recognition followed quickly. The Grodan Group was the first substrate supplier to obtain ISO 9001/14001 certification, the Kiwa Keur (quality certificate) and the European Eco-label. At the same time, the Group extended its reach further and further. It is now a worldwide enterprise, active in over sixty countries, from America to Asia.
