The growing global population and urbanization are positively impacting the water treatment industry. People’s access to clean drinking water directly affects their health, making it a vital issue. The chlor-alkali industry is benefitting from this as chlorine and sodium hydroxide are extensively used in water treatment systems. Chlorine serves as a disinfectant to eliminate bacteria and other microorganisms that may contaminate water. It is a strong water sterilizing agent and helps purify water that is delivered to homes and industries.
Globally, both developed and developing countries have been increasing the use medicinal chlorine for water treatment. For instance, as UNICEF reported in 2020, more than 800 million people lacked basic drinking water services, and water disinfection systems require further strengthening.
As more communities are to be provided access to safe water in coming years, the consumption of chlorine is projected to rise further. In addition to chlorine, the increasing complexity of water generated from various sources like surface water, seawater, and industrial wastewater has necessitated advanced treatment methods that employ caustic soda (sodium hydroxide) on a large scale.
Sodium hydroxide serves the purpose of pH balancing and eliminating heavy metals through coagulation and precipitation processes. It is important in the secondary and tertiary stages of water treatment. With sodium hydroxide being extensively used in water treatment, there is expected to be great change in the usage of sodium hydroxide for water treatment industrially over the next ten years. This is expected to support the growth of the chlor-alkali industry.
According to UN Water reports, the world is running out of freshwater. Industrialization, pollution, and climate change are responsible for water scarcity in various regions of the world. The sodium hydroxide market in the water treatment industry is anticipated to boost considerably in the next decade. This is good news for the chlor-alkali industry as whole.
Production of a variety of organic chemicals is another significant end-use sector where chlor-alkali chemicals are applied. Chlorine serves as a precursor or a raw material for several commodity chemicals, including vinyl chloride monomer (VCM), ethylene dichloride (EDC), polyvinyl chloride (PVC) resins, ethylene, propylene oxide, and others. These chemical intermediates are further processed into components for a multitude of industrial and consumer goods.
In supported regions, the global production of organic chemicals surged recently as a result of expanding markets like consumer durables, automotive industry, packaging, construction, and agrochemicals. There is also growing manufacturing activity in Asia Pacific and Latin America, which further stimulates domestic demand for organic chemicals alongside the international demand.
To expand access to domestic and foreign clients, chemical companies are investing heavily in facilities that produce organic chemicals. As this increase in production happens, the worldwide demand for chlorine and chlor-alkali products will continue to experience vigorous growth.
The construction industry’s increasing need for PVC creates a significant opportunity for expansion within the chlor-alkali market at a global scale. Due to its diverse characteristics and cost effectiveness, PVC or polyvinyl chloride is one of the most popular plastics in the construction industry. It is simple to cast into different shapes such as pipes, window frames, siding, flooring, and even as insulation boards.
Some numbers illustrate the sheer magnitude of construction projects taking place globally and the surge in demand for PVC. As reported by the United Nations, the global spending on infrastructure is projected to reach USD 94 trillion by 2040 for the building of roads, bridges, utilities, among other construction requisites. This will be due to accelerated urbanization where people move to cities for better living standards and job opportunities.
Asia and Africa are expected to account for roughly two thirds of all infrastructure spending in the next 20 years. China alone has plans for over USD 12 trillion in new projects by 2030. As development-stage economies focus on more housing, transport, and energy facilities, the availability of PVC materials will have to meet demand.
In terms of product, soda ash is expected to contribute 53.8% share of the market in 2025 owing to its increasing use in the flourishing pulp and paper industry. Soda ash, also known as sodium carbonate, acts as an important raw material in the manufacturing of paper. It has alkalinity properties that help remove lignin from wood fibers to extract cellulose needed for paper production. With more nations pushing initiatives to reduce reliance on plastics and increase paper product usage, pulp and paper companies are ramping up capacities. This bodes well for soda ash demand.
Additionally, growing e-commerce is propelling corrugated packaging board demand, another major end-use for soda ash. Further, favorable government policies in developing nations supporting local paper industries also aids the soda ash market. Its cost-effectiveness relative to substitute products cements soda ash's dominant position
In terms of production process, membrane cell is expected to contribute 43.8% of the market share in 2025 owing to its technology advantages over traditional processes. Membrane cell technology provides higher energy efficiency and yields compared to diaphragm cell methods. It allows producers to reduce operating costs and lower carbon footprint.
Additionally, membrane cells offer improved safety with reduced risk of gas leaks. Their modular design also enables easy capacity expansions. With sustainability and cost savings in sharp focus, many chlor-alkali companies are retrofitting plants or constructing new production facilities based on advanced membrane cell systems.
Government incentives for green technologies further accelerate widespread adoption. R&D continues to enhance membrane cell performance, helping cement its position as the preferred production process.
