These chemicals are derived from biodegradable, non-toxic, and eco-safe ingredients, and are designed to minimize harmful environmental impacts while maintaining efficiency in applications such as industrial wastewater treatment, municipal water systems, and commercial water purification. Unlike conventional water treatment chemicals, green alternatives are engineered to comply with stringent environmental regulations and support sustainable water management practices.

The market is witnessing steady growth, driven by increasing environmental awareness, tightening regulatory frameworks, and rising demand for sustainable water management solutions across industrial, residential, and municipal sectors. Key end-users include power generation, food and beverage, chemical manufacturing, oil & gas, and water utilities. As companies and governments prioritize eco-friendly operations and carbon reduction, investments in green chemistry for water treatment are expanding. Innovation in plant-based formulations and low-emission technologies is further propelling market adoption, making green water treatment solutions a vital component of the transition to a circular and sustainable economy.

Key Developments:

• In April 2025, the UK Ministry of Defence began investigating PFAS contamination at military bases, including RAF Marham and RM Chivenor. These chemicals, used in firefighting foams, have led to significant environmental contamination. The investigation comes amid growing concerns about water quality and public health.
• In December 2024, Gradiant launched CURE Chemicals offering over 300 eco-friendly formulations for water and wastewater treatment. This new product range includes corrosion inhibitors, coagulants, and biocides. CURE Chemicals aims to enhance treatment efficiency while minimizing environmental impact. This move highlights the industry's shift toward sustainable water treatment solutions.

Green Water Treatment Chemicals Market Segmentation:

Based on the product type:

• Coagulants & Flocculants
• Biocides & Disinfectants
• Corrosion Inhibitors
• Chelating Agents
• Scale Inhibitors
• pH Adjusters & Stabilizers
• Others (e.g., anti-foaming agents, dispersants)

The coagulants and flocculants segment is anticipated to lead the market, driven by their widespread application and high demand across municipal and industrial water treatment sectors. These eco-friendly alternatives play a crucial role in separating suspended solids and organic matter from water, improving clarity and reducing contamination levels. The growing need for efficient wastewater treatment, especially in regions facing water scarcity and pollution challenges, is propelling the adoption of green coagulants and flocculants. Their biodegradability and low toxicity make them a preferred choice in environmentally conscious operations, positioning them as a dominant segment in the market.

Based on the source:

• Plant-Based
• Microbial-Based
• Mineral-Based
• Others

Based on the source, plant-based green water treatment chemicals are projected to lead the market due to their natural origin, biodegradability, and minimal environmental impact. Derived from renewable sources such as plant extracts, starches, and natural polymers, these chemicals offer a sustainable alternative to synthetic agents without compromising treatment efficiency. Their increasing adoption is driven by stringent environmental regulations and growing demand from eco-conscious industries seeking non-toxic and residue-free solutions. Plant-based options are especially favored in sectors like food & beverage and municipal water treatment, where safety and sustainability are paramount. Their scalability and consistent performance further reinforce their leading position in the market.

Based on the application:

• Cooling Water Treatment
• Boiler Water Treatment
• Raw Water Treatment
• Wastewater Treatment
• Process Water Treatment

The wastewater treatment segment is expected to dominate the market due to the rising global focus on water reuse, pollution control, and sustainable waste management. Increasing industrial discharge, urban population growth, and tightening environmental regulations are pushing both municipalities and industries to invest in advanced, eco-friendly treatment methods. Green chemicals used in wastewater treatment offer the dual benefit of efficient contaminant removal and reduced ecological harm, making them ideal for meeting compliance standards. As countries aim to minimize freshwater consumption and adopt circular water use practices, the demand for green solutions in wastewater treatment continues to rise significantly.

Based on the end user:

• Municipal
• Industrial
• Commercial
• Residential

Within the end-user segmentation, the municipal sector is anticipated to lead the market, driven by the growing need for sustainable water management in urban and rural communities. Municipalities are under increasing pressure to provide safe, clean water and manage wastewater effectively while complying with strict environmental regulations. Green water treatment chemicals offer a viable solution by ensuring effective purification with minimal ecological impact. The demand is further boosted by government initiatives promoting green infrastructure, public health priorities, and the need to modernize aging water treatment facilities. This sector’s scale, responsibility, and regulatory alignment position it as the dominant market driver.
