 The hospitality industry is increasingly aware of the potential benefits of integrating nature-based solutions into their operations to reduce their environmental impact while maintaining or improving service levels. One such solution is constructed wetlands, CWs. These systems use natural processes to treat wastewater and have been shown to be effective at removing pollutants from wastewater streams. Studies on CWs have been conducted in Europe, Asia and South America and have demonstrated high removal rates for various contaminants. Additionally, CWs are compact and require less space than other wastewater treatment technologies, making them ideal for applications in the hospitality industry.
