Growing more with less

Growing food sustainably and efficiently

The global food production system is under pressure. We need to find more sustainable ways of feeding a growing, more urbanised population. ROCKWOOL products enable modern horticulture to increase production while using fewer natural resources.

In places where agricultural land is scarce, new and innovative forms of food production hold the key to feeding city dwelling populations. Grodan hydroponics can be sited anywhere, including in urban areas that would otherwise be completely unsuitable for traditional soil-based production.

Relative to growing in soil-based systems, Grodan products sold in 2018 resulted in an estimated 94 million litres less water used. Grodan products also saved nearly 26 000 hectares of land, an area almost three times the size of Paris.

Dutch greenhouse with tomatoes grown in GRODAN

ROCKWOOL collaborates with Wageningen University

Wageningen University & Research developed an estimation model comparing soil based and mineral wool based cultivations systems in three distinct climate zones for crops like tomato and cucumber

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 2017 resulted in an estimated 94 million litres less water used, more than 17,000 tonnes of fertilisers, and generated and extra yield of more than 1.9 million tonnes of vegetables.
