Chlor Alkali Market Trends

Rising Adoption of Greener Production Technologies by Major Manufacturers to Bolster Market Growth

Chlor alkali production technology is subjugated by using membrane cell technology. However, many production facilities still operate using the mercury cell process. Mercury is a highly toxic element, and environmental concerns have compelled lawmakers to implement stringent environmental regulations on such processes. As a result, manufacturers are converting their mercury cell technologies to greener technologies such as membrane cells. In recent times, many plants in Europe converted their technologies, and the same is likely to get reciprocated in different parts of the world in the coming years on the back of rising environmental concerns. Asia Pacific witnessed a chlor alkali market growth from USD 30.46 billion in 2022 to USD 31.09 billion in 2023.

Chlor Alkali Market Growth Factors

Rising Demand for Vinyl Polymers to Augment Market Growth

Chlorine is used in large quantities in vinyl production. Various downstream chemicals are produced using chlorine that is further used to manufacture polyvinyl chloride (PVC). PVC is the world’s third-largest used polymer. It is prominently used in the construction industry to make pipes, window frames, and other products. The thriving construction industry in emerging countries has boosted the demand for chlorine in vinyl production. Moreover, PVC applications in various end-use industries are steadily increasing, which is expected to generate lucrative growth opportunities in the forthcoming years. For example, PVC tapes and cases are healthily used in electrical applications due to their unique properties. The emergence of electric vehicles in the developing world is likely to boost the consumption of PVC and chlorine used in vinyl. Thus, healthy demand from end-use industries is expected to drive the market.

Expanding Water Treatment Industry is Contributing to the Growth of the Market

The water treatment industry is witnessing considerable growth, resulting in a surge in product demand. This is primarily because chlor alkali is a crucial component used in water treatment plants to produce sodium hypochlorite. This disinfectant is widely utilized for treating drinking water and wastewater. Sodium hypochlorite is known for its effective and reliable disinfection properties, which makes it an indispensable element for ensuring the safety and purity of water.

Moreover, the expanding population and increasing industrialization have increased water pollution levels, further fueling the demand for water treatment solutions. As a result, the water treatment industry is projected to grow significantly in the coming years. Furthermore, chlor alkali is used to produce a wide range of products, such as paper, textiles, detergents, and plastics. Therefore, the increasing demand for these products will also contribute to the chlor alkali market growth.

RESTRAINING FACTORS

Stringent Environmental Regulations Confines the Market Growth

The market is exposed to various environmental regulations around the world. Mercury cell production technology has a high risk of polluting water bodies and other ecological bodies. Consequently, lawmakers are implementing stringent environmental regulations on such production processes. Moreover, the European chlor alkali industry already phased out membrane cell technology used in chlorine production after the European Union passed a regulation in 2017. Similarly, regulations are being made around the globe to minimize the impact on the environment. For Instance, Canada also amended chlor alkali Mercury Liquid Effluent Regulations.

Vinyl segment dominates the consumption of Chlorine and Alumina leads the Market growth for Caustic Soda

Based on application, the market is segmented into chlorine (water treatment, paper & pulp, inorganics, intermediates, organics, vinyl, and others) and caustic soda (textile, alumina, soap & detergents, organics, inorganics, pulp & paper, water treatment, and others). The vinyl segment dominates the global market in terms of chlorine consumption. Chlorine derivatives are prominently used in PVC production. The chlorine demand often fluctuates in tandem with the production of PVC. Besides, chlorine produces several organic, inorganic, and intermediate chemicals that collectively account for over one-third of global consumption. Water treatment and paper & pulp account for a single-digit share in chlorine consumption.

On the other hand, the alumina segment dominates the caustic soda market in terms of revenue and volume. The increasing use of aluminium in the automotive industry is set to aid the growth of caustic soda consumption. The organics segment accounted for the second-largest share due to the healthy adoption of caustic soda in the organic chemical industry. Textile is the second-fastest-growing segment used for scouring, mercerization, and dyeing in the textile industry. Soap & detergent segment has been one of the first industrial users of caustic soda. The strong presence of alternatives has hampered the adoption of caustic in soaps and detergent applications. Pulp & paper, inorganics, water treatment, and others accounted for around half of the global demand for caustic soda.
