“Vertical farms are all about minimizing carbon footprint, but today they still rely heavily on CO2 in cylinders or tanks, which is produced mainly as a byproduct of fossil fuels. Skytree’s decentralized direct air capture units can help close the loop,” says Max Beaumont, founder of Skytree.

“Our direct air capture technology makes it easier for vertical farms to make the switch to a cleaner and more reliable way to supply their plants with CO2. A truly circular method is meeting our needs for a sustainable economy in the long term,” he adds.

Proliferation of vertical farming is widely seen as a feather in the cap of a sustainable economy. Ard van de Kreeke, the founder of Growy, says, “Vertical farming has gained a lot of interest over the last few years because of its promise of sustainable food production.”

However, he also cautions about the fact that vertical farms are currently not as sustainable as we think. At Growy, he says they are working hard on creating a completely circular and sustainable farm. “Local and sustainable food production have gained a lot of interest and is also something that aligns well with Amsterdam’s policies on food production and sustainability,” says Ard.

While the interest in sustainability and vertical farming continues to grow, it is not necessarily helping with funding. Ard says raising funds is “still very difficult,” and the sustainability part has not driven investors to invest. The investment climate has especially turned cold for startups and scaleups in the last few months.
