Water reuse: the new regulatory framework driving water sustainability

The approval of Royal Decree 1085/2024, which establishes new regulations for water reuse in Spain, represents a turning point in the management of water resources in our country. In a context marked by climate change, with prolonged periods of drought that particularly affect our territory, this regulatory framework is a practical and necessary response to ensure a more efficient and sustainable use of water, an increasingly scarce and valuable resource. The new decree introduces important developments, especially in sectors such as the food industry, by allowing the use of reclaimed water for specific processes. As a result of this regulation, this water can be used for tasks such as cleaning raw materials, materials in contact with food, or for use in closed-loop cooling systems and steam production. However, this is always subject to the strictest quality standards. This approach, in addition to optimizing the use of drinking water, will also allow us to reduce pressure on water resources by reorganizing them and allocating them to more essential purposes. Furthermore, the new regulation strengthens synergies with other environmental policies such as the European Green Deal and the sustainable agri-food systems promoted by the European Union. All of this aligns with international efforts that, through the Codex Alimentarius, advocate for a more balanced management of natural resources and greater flexibility in water use, always prioritizing food safety. At Edison Next, the reuse and optimization of water use is one of the foundations of our circular economy strategy, along with Energy Efficiency, renewable gas generation, and carbon capture and use (CCU). We are committed to offering companies and institutions innovative solutions that not only comply with regulations but go further, helping them transform environmental challenges into opportunities for sustainability and profitability. Our water treatment solutions are a clear example of this approach. Through advanced technologies, we transform wastewater treatment plants into highly efficient biofactories, capable of recovering and reusing water safely and sustainably, improving business operations and reducing operating costs. Additionally, these biofactories have the potential to generate valuable by-products, such as bioCO2, which is used to reduce dependence on fossil-based chemicals in industrial processes. This approach not only minimizes the environmental impact of our clients but also strengthens their competitiveness by aligning their activities with consumer expectations and the demands of an increasingly demanding market in terms of sustainability. A clear example of our expertise in water reuse is the project developed for Grupo Pascual. As part of its decarbonization strategy, we have transformed the wastewater treatment plants at its facilities in Aranda de Duero into advanced biofactories. Thanks to this initiative, these facilities now produce biogas and bioCO2, contributing to the generation of clean energy and closing the water cycle by enabling its reuse. This project has not only allowed Pascual to advance towards its goal of being a Net Zero company by 2026 but has also generated tangible benefits, such as reduced drinking water consumption and significant economic savings. Furthermore, it reinforces its leadership in the food sector in terms of sustainability and environmental responsibility. At Edison Next, we believe that water reuse is not only an environmental necessity but also a key business opportunity. Companies that integrate circular economy solutions into their operations will not only comply with regulations but will also improve their profitability, strengthen their reputation, and actively contribute to the fight against climate change. With the support of regulations such as the new Royal Decree, we are convinced that sustainable water management will be a fundamental pillar for building a greener and more resilient future. At Edison Next, we will continue working with this purpose, leading projects that demonstrate that sustainability, in addition to being a goal, is the right path towards a better world.
