In response to the escalating demand for water and the alarming pollution levels affecting water bodies, wastewater reuse plays a fundamental role in addressing the water crisis. Based on the principles of the circular economy framework, regeneration should be a key element of today’s and future urban water management strategies. Therefore, wastewater treatment should not only focus on safeguarding public health and minimizing the environmental repercussions of wastewater disposal, meeting discharge regulations at a minimum cost, but also as a source of non-conventional resources with significant economic and environmental value. Notably, the use of regenerated water in industrial contexts represents a comprehensive strategy that bridges regulatory compliance, resource conservation, cost-efficiency, and environmental sustainability. By adopting these innovative practices, industries are not only meeting their legal obligations but also taking proactive steps towards a more sustainable and responsible approach to their operations. Since the textile industry is notorious for its extensive water usage, the treatment and recycling of wastewater can significantly reduce these industries’ dependence on freshwater supplies, a critical concern in areas facing water scarcity.
