- Zero Liquid Discharge (ZLD) is a wastewater management approach that ensures that no liquid waste leaves the system, making it vital for industries under pressure to meet stringent discharge regulations. It is increasingly adopted in power generation, chemicals, pharmaceuticals, food & beverage, and textile industries
- The rising demand for ZLD systems is fueled by increasing industrialization, tightening environmental norms (e.g., by EPA, EU directives, and CPCB in India), and a growing emphasis on corporate sustainability goals
- Asia-Pacific dominates the Global ZLD Market, with the largest revenue share in 2025, due to strong industrial activity, government initiatives for pollution control, and growing ZLD mandates in China and India
- North America is expected to be the fastest-growing region, driven by strict regulatory frameworks, technological innovation, and the adoption of water recycling systems in key industries like oil & gas and pharmaceuticals
- The chemical & petrochemical segment is anticipated to lead the ZLD market with a significant market share, supported by high wastewater generation, complex effluents, and the necessity of meeting compliance standards
