Greenhouses in Europe and the Mediterranean produce 30% of the EU’s fruits and vegetables, yet are facing growing pressures on potable water use for irrigation - leading to the use of more efficient irrigation techniques together with non-potable water sources. The combination of these entails a strong and growing need for irrigation water treatment (IWT), to eliminate water-borne plant and human pathogens, to mitigate irrigation line clogging by bio-foul, and to improve water oxygenation. Our goal is to bring to market a novel irrigation water treatment (IWT) solution based on our technology breakthroughs in on-site generation of hydrogen peroxide (H2O2). Our compact and autonomous H2O2 generation device (HPGen) enables the safe, cost-effective and sustainable on-site generation of hydrogen peroxide, using only water, air and electricity as input. Hydrogen peroxide is a highly potent but eco-friendly disinfection and oxygenation agent, yet its use in IWT is very limited due the costs, risks and complexities of present-day H2O2 supply chain. HPGen will disrupt today’s hydrogen peroxide supply chain, and enable growers to reap the benefits of its use in IWT. In doing so, HPGen will substantially decrease grower’s IWT and irrigation line maintenance costs, eliminate the use of chlorine and other toxic-chemicals in IWT, improve farm safety and plant health, increase crop yields, and enhance agriculture sustainability and reduce its environmental impact – resulting in a positive economic impact for growers of €4k-€5k / ha per annum.
