Excel Industries is fundamentally a technology house built on phosphorus chemistry - it has spent over eight decades turning a single reactive element into a portfolio of intermediates, performance chemicals and pharma ingredients, all made with processes it developed itself. Founded in 1941 to make India self-reliant in chemicals, the company commissioned the country’s first indigenous phosphorus plant in 1972 and has never stopped backward-integrating: it makes its own basic derivatives, runs its own R&D, and even generates nearly half its electricity from renewables. The recurring approach is simple - own the chemistry from the raw-material stage, keep the balance sheet debt-free, and let one generation of cash flows fund the next generation of products.
Business segments
Two engines at different stages - a chemicals core that supplies the world’s agrochemical and industrial supply chains, and a tiny but pioneering waste-management division that turns organic and construction waste into compost, biogas and recycled building materials.
1. Chemicals: where the phosphorus know-how lives
A deep-backward-integrated phosphorus-chemistry platform that makes the intermediates other chemical companies need, with global number-one positions in select products and a growing contract-manufacturing arm that puts its idle reactor capacity to work for multinational customers.
- World’s top maker of a key agrochemical building block - Excel is the number-one producer of DETC (Diethyldithiophosphoryl Chloride) globally, an intermediate used in organophosphorus insecticides and herbicides that the company has been manufacturing for four to five decades.
- Four product groups under one roof - the division spans agrochemical intermediates (50-60% of revenues), yellow-phosphorus derivatives like P2S5 and PCl3, performance solutions including phosphonates and biocides, and pharma intermediates and APIs for gout and diabetes, all made across three manufacturing sites in Maharashtra and Andhra Pradesh.
- Backward integration is the cost moat - the company manufactures its own basic phosphorus derivatives in-house rather than buying them, and it sources almost no raw materials from China, which shields it from the supply and pricing swings that affect competitors dependent on Chinese inputs.
- Contract manufacturing turns fixed assets into annuities - a five-year supply agreement with a multinational signed in 2024 marked the entry into dedicated contract manufacturing, and a second deal with an Indian specialty-chemicals company will add a new dedicated production line by mid-2026, funded partly by a Rs 25 crore customer advance.
- Flexible plants, not single-product pipelines - the asset base is highly fungible, with 19 unit processes and two million litres of process volumes running at 70-75% average utilisation, so the company can shift production toward whichever product group - agrochemicals, performance solutions, or pharma - is seeing stronger demand at any point in the cycle.
2. Environment and Biotech: a small-scale pioneer in waste-to-resource
A niche division that designs and operates composting, biogas and construction-waste plants for municipalities and institutions, representing roughly 1% of revenues but carrying the company’s sustainability ethos into physical infrastructure.
- Decentralised composters for kitchens and canteens - the Excel Organic Waste Converter handles up to two tonnes per day of organic waste on-site, turning it into compost for residential societies, hotels, hospitals and office canteens, and the division has exported these systems to the Maldives and is expanding its presence in markets such as Chile and the Philippines.
- Municipal-scale plants under long-term contracts - a construction-and-demolition waste processing plant in Rajkot runs under a 20-year public-private partnership, producing recycled aggregates and paver blocks, while a 50-tonne-per-day dry-waste sorting facility in Pune operates under a 10-year municipal contract.
- Biogas is the newest municipal offering - the division commissioned its first five-tonne-per-day biogas project in Maharashtra and handed over a plant to Chiplun Municipal Council, qualifying it to bid for similar-sized projects elsewhere.
- Loss-making centralised plants have been exited - the division closed its first large municipal solid-waste processing plant at Pirana, Ahmedabad, due to persistent financial losses, and returned the Varanasi plant to NTPC after completing the contract, refocusing on smaller, viable installations.
Group structure and partners
A promoter-led, publicly listed company with a clean holding structure, three subsidiaries that house its waste-management and investment activities, and a captive solar-power partnership that locks in green electricity for 25 years.
- The immediate parent is Anshul Specialty Molecules Private Limited, which held 42.63% of Excel as of March 2025, with other promoter-group entities holding smaller stakes.
- Three subsidiaries sit under Excel: Kamaljyot Investments Limited, a wholly owned NBFC for investment holding; Excel Bio Resources Limited, formed for waste processing; and Excel Rajkot C&D Waste Recycling Private Limited, an 80%-owned special-purpose vehicle that runs the Rajkot construction-waste plant.
- Two associate investments were divested to the Executive Chairman in 2025 - the company sold its stakes in Climacrew Private Limited and Mobitrash Recycle Ventures Private Limited, simplifying its non-core holdings.
- Excel owns 28.83% of First Energy 7 Private Limited, a Thermax-group SPV that built a captive solar-power plant supplying electricity to Excel under a 25-year arrangement, which helped the company source nearly 48% of its power from renewables.
- The original agri-inputs division was spun off as Excel Crop Care in 2003, leaving the current entity focused entirely on chemicals and waste management.
