Annual output exceeds 70 million metric tons, driven by the chlor-alkali process that co-produces sodium hydroxide and hydrogen. Demand tracks PVC, water treatment, and a broad set of intermediates. Roughly 35 to 40 percent of chlorine feeds the EDC-VCM-PVC chain. Asia-Pacific accounts for about 40 percent of global demand and continues to add capacity alongside downstream PVC. You should expect a steady shift in volumes toward construction, infrastructure, and urban services across India, Southeast Asia, and China.
Growth rests on three pillars. First, construction and infrastructure keep PVC demand resilient, with residential and utilities spend supporting pipes, profiles, and wiring. Second, municipal and industrial water markets expand, supported by stricter disinfection rules and water reuse. Many cities target chemical spend growth of 6 to 8 percent annually. Third, food safety standards lift usage in sanitation; typical chlorine concentrations range from 50 to 200 ppm for food-contact surfaces. On the supply side, electricity is the largest cost line; membrane cells typically consume 2,200 to 2,500 kWh per metric ton of chlorine. This makes regional power prices a key margin driver.
Risk factors are clear. Chlorine transport is limited, so producers rely on co-located demand or conversion to derivatives such as EDC and PVC. Co-product balancing with caustic soda can tighten availability or cap run rates. Formation of disinfection by-products, including trihalomethanes, prompts tighter limits in some markets and supports a gradual shift to on-site hypochlorite generation or alternative oxidants in sensitive applications.
Technology upgrades shape cost curves. Continued conversion from legacy cells to membrane plants cuts energy intensity by double digits and removes mercury-related liabilities. In India, the PAT scheme encourages higher-efficiency operations and membrane adoption. In Europe, prior mercury phase-out and recent energy volatility prompted capacity rationalization, improving utilization of remaining assets. In North America, debottlenecking aligns with stable power and integrated PVC chains. The Middle East presents an emerging investment case tied to integrated petrochemicals and salt resources. For investors, Asia-Pacific PVC, regulated water markets, and energy-advantaged chlor-alkali sites are the primary hotspots over the next decade.
