From growing medium to brick ›

22 December 2015

Sustainability. It's a major global concern. And it is for us at GRODAN too. As producers of stone wool substrates, ‘sustainability’ for GRODAN extends far beyond the boardroom and a few lines on the website. Sustainability is evident in everything we do as an organisation. Not only as our contribution to creating a better world, but also helping growers meet the challenges of the constantly changing marketplace. At GRODAN we're not 'being green' simply for show. For us, sustainability forms the guiding principle underlying our technological innovation. Facilitating even smarter cultivation on stone wool growing blocks and slabs, today and in the future. Good for the environment, good for consumers and good for growers too.
