What SFC Environmental Technologies Ltd. does

SFC Environmental Technologies Ltd., founded in 2005 and headquartered in Navi Mumbai, India, designs, manufactures, and commissions wastewater treatment plants for municipal corporations and industrial customers. The company's flagship offering is the proprietary C-Tech Sequencing Batch Reactor (SBR) technology, which holds over 80% market share in India's SBR segment and has been deployed across 639 commissioned plants with cumulative treatment capacity of 15,000+ MLD across 25+ states. The technology stack is anchored by C-Tech and MABR for biological treatment, complemented by Fiber Disc Filters, Membrane Bioreactor, Submerged Ultrafiltration, and Closed Circuit Reverse Osmosis for recycle/reuse, plus energy-efficiency systems (Turbo Blowers, Wendewolf solar sludge drying). All systems are integrated with PLC/SCADA automation and supported by a 48-member in-house Erection and Commissioning team that delivers approximately 80 plant commissions annually.

The company operates a vertically integrated manufacturing model, with critical components (decanters, diffusers, panels) produced in-house at a 200,000 sq ft facility commissioned in 2023 and expanded tenfold within two years. Revenue is generated through technology supply and equipment sales, full-cycle engineering design and commissioning services, and post-handover operations and maintenance support, with pricing structured on a project-by-project basis tied to plant capacity in MLD. Customers are primarily Indian municipal governments reached through competitive bidding, alongside industrial customers in pharmaceuticals, textiles, food and beverage, and chemicals. Major project execution is conducted through EPC partnerships with engineering firms such as Larsen and Toubro, as exemplified by the 424 MLD Pirana STP in Ahmedabad under the World Bank-funded Gujarat Resilient Cities Partnership Programme. The company filed a Draft Red Herring Prospectus with SEBI in August 2025 in preparation for a public listing and operates a solid waste management subsidiary, Hindustan Waste Treatment.
