Growing a kilo of tomatoes takes 60 liters of water. What if just 4 liters of water provided the same yield?

17/07/2017 - You would not only be using water more efficiently, but you’d also be contributing to the vitality of sustainable cities - soon to become significant contributors to the future dynamics of a changing planet. By the way, producing a kilo of tomatoes does require only 4 liters of water when grown in a state-of-the-art greenhouse using stone wool solutions.

By 2050, the earth’s population is estimated to reach 9 billion, and 70% of world’s people will live in cities. Modern, sustainable cities will be critical to influence the demand water, food and energy for the majority of people on earth. Greenhouses located in proximity of urban centres will play an increasing role in providing fresh, high-quality fruits and vegetables, while also managing the growing challenges of water scarcity.

Growing a kilo of tomatoes in the field requires 60 liters of water. In a state-of-the-art greenhouse with stone wool, it would take only four.

The ROCKWOOL Group, a global leader in sustainability solutions, cares deeply about the impact greater urbanization can have on the planet and its people.

ROCKWOOL is committed to enriching lives through its stone wool products that insure superior insulation, protect against fire and water damage, reduce noise pollution, and even make large-scale horticulture a reality.

Plus, ROCKWOOL stone wool growing solutions can be sited anywhere - especially in urban areas and in unused buildings - to grow fresh food sustainably in densely-populated areas.

Just one cubic metre of basalt is needed to produce 50 cubic metres of stone wool - enough to grow 350,000 kg of tomatoes, 1 million cucumbers, or 175,000 peppers in a sustainable manner. Remarkably, the stone wool created from that initial cubic metre of basalt can also be re-used as raw material to produce 8 cubic metres of brick.

Recycling stone wool after use means using fewer raw materials, while reducing the footprint on our planet.

Cities have a vital role to play in solving the world’s food-growing problems. If you’d like to learn more about sustainable agriculture or other areas supporting modern living, click here: http://www.rockwool.com/group-profile/modern-living/topics/modern-agriculture/
