A recent study conducted in the United States found that wastewater can be used effectively as a growing medium for hydroponic farming . This discovery could transform the way water is used in agriculture, providing a sustainable solution for crop irrigation while reducing costs. As an example, lettuce cultivation has been successfully tested, demonstrating that the nutrients present in wastewater can be sufficiently purified and adapted to support growth healthy plant health.
The study highlights the enormous potential of this innovative approach. The use of wastewater in hydroponics not only recycles a valuable resource, but it also reduces the dependence on chemical fertilizers, which are often expensive And harmful to the environment. The researchers emphasized that purification steps are necessary to eliminate contaminates . However, this process is less energy intensive than traditional water treatment methods. In 2023, hydroponic agriculture represented about 1.5% of total agricultural production in the United States, but this proportion is constantly increasing thanks to such innovations innovations.
