At ROCKWOOL Group, we’re committed to all aspects of circularity – and this includes rethinking how we use resources every day. The global food production system is under pressure, and the need to find more sustainable ways of feeding a growing and more urbanised population is becoming urgent. Our Grodan hydroponic products address this concern and enable food production in urban settings using fewer natural resources.

Dutch greenhouse with tomatoes grown in GRODAN

Since 2017, ROCKWOOL have collaborated with Wageningen University in the Netherlands to quantify the positive impact of growing tomatoes and cucumbers in Grodan horticultural substrates compared to greenhouse grown, soil-based crops. The results are  significant. 

Relative to growing in soil-based systems, Grodan products sold in 2019 resulted in an estimated 100 million litres less water used, more than 17,000 tonnes of fertilisers saved, and generated an extra yield of more than 2.1 million tonnes of vegetables.
