With freshwater scarcity becoming a global concern, industries are under growing pressure to adopt sustainable wastewater management practices. Zero Liquid Discharge (ZLD) systems offer a comprehensive solution by treating and recycling industrial effluents until no liquid waste remains. Beyond environmental compliance, these systems are increasingly viewed as enablers of a circular water economy, allowing industries to reuse water while recovering valuable by-products such as salts and minerals. According to Stratview Research, the Zero liquid discharge systems market size was USD 8.30 billion in 2024 and is expected to reach USD 9.03 billion in 2025 to USD 16.04 billion in 2032, witnessing a market growth (CAGR) OF 8.5% during the forecast period of 2025-2032.

The Zero Liquid Discharge Systems Market is projected to grow robustly, supported by stringent environmental regulations, rapid industrial expansion, and technological advancements in modular and energy-efficient ZLD solutions.

Key Market Drivers

• Industrial growth – High-water-use industries such as power, textiles, and chemicals drive ZLD adoption.
• Modular systems – Scalable and cost-effective modular ZLD designs are gaining popularity, especially in emerging economies.
• Energy efficiency – Innovations in low-energy evaporation, advanced membranes, and hybrid systems reduce operational costs.
• Water scarcity – Regions facing water stress are accelerating ZLD deployment for sustainable reuse.
• ESG compliance – Corporates are integrating ZLD into their sustainability and resource management strategies.
