JG Chemicals is fundamentally a recycling business that turns industrial waste into an irreplaceable ingredient for tyres. Born from a single 600-tonne plant in Kolkata in 1975, it has grown over five decades into India’s largest zinc oxide manufacturer and one of the top five globally, serving nine of the world’s ten biggest tyre companies. The recurring approach that explains everything else is a circular-economy model built on proprietary recycling technology, transparent cost pass-through to customers, and multi-decade relationships with both scrap suppliers and tyre makers - a combination that has made it the consolidator in a fragmented market.
Business segments
A single recycling engine at different stages of maturity - a zinc oxide cash cow, a young zinc sulphate business feeding the same agricultural market, and an emerging recycled-rubber adjacency that sells more into the same tyre customers - all built on the same proprietary scrap-processing backbone.
1. Zinc oxide: the tyre industry’s irreplaceable ingredient
The company converts zinc dross - a waste byproduct of steel galvanising - into over 90 specialised grades of zinc oxide using a proprietary French Process, and tyre makers cannot make rubber without it.
- Waste in, high-purity chemical out - the company uses 100% recycled zinc scrap for most grades, reserving virgin zinc only for high-end pharmaceutical and chemical applications, which gives it a cost advantage over competitors who blend the two. Its in-house recycling technology can process inferior grades of scrap that rivals cannot handle, and that know-how is notably difficult to replicate.
- No two customers want the same thing - zinc oxide is not a generic product; each tyre manufacturer requires a tailor-made grade with specific chemical and physical properties, and the company’s ability to customise across more than 90 grades is a key differentiator. Tyre and rubber accounts for roughly 85% of revenue, and the company supplies every major Indian tyre maker and nine of the world’s top ten - including Bridgestone, Michelin, Goodyear and Continental.
- The pricing formula removes the gamble - both raw-material buying and finished-product selling are indexed to the London Metal Exchange zinc price on an M-minus-1 basis, meaning the selling price is set using the previous month’s LME. The company transparently passes on higher freight, energy and other costs to customers, and its long-standing relationships mean those revisions are accepted.
- A global supply web built over decades - the company sources from over 100 suppliers across 50 countries, built through trusted relationships with family-owned businesses, and has a two-decade-plus track record of honouring every commitment, making it the preferred customer for the majority of dross suppliers globally. Small players have struggled with raw-material disruption, while the company’s network is the biggest constraint for any would-be entrant.
- The moat is time, not just scale - securing vendor approval with a major tyre company takes at least four to seven years, and tyre makers have spent the past two decades consolidating their supplier base toward large, established vendors. Between 2017 and 2021, a period with no volume growth in tyre production, the company’s volumes grew at a 13.3% compound rate as customers consolidated their buying. No major new entrant has emerged in the domestic zinc oxide market in the past decade.
2. Zinc sulphate and allied chemicals: turning in-house ash into agricultural nutrition
The company takes zinc ash generated as a byproduct of its own zinc oxide process and converts it into zinc sulphate - a micronutrient for zinc-deficient soils, with the largest plant in Southern India.
- Waste from one process feeds another - the majority of the zinc ash used is generated in-house during zinc oxide manufacturing, and the plant uses Zero Liquid Discharge technology, so no wastewater leaves the site. This makes the business an extension of the recycling logic rather than a standalone venture.
- Built where the soil needs it most - the 10,080-tonne facility at Naidupeta, Andhra Pradesh, sits in a region where soils have high zinc deficiency, putting production close to the farmers who will use it. The company is developing its own brand for deeper market penetration and exploring exports by cross-selling to its existing customer base.
- Small today, with a long tail of demand - zinc sulphate currently makes up less than 5% of revenue, but the addressable market spans agriculture, pharmaceuticals and nutritional supplements, and the company also produces recycled zinc ingots from the same recycling stream.
3. Recycled rubber and new adjacencies: more content per tyre
The company is developing a recycled-rubber business that sells into the same tyre customers it already serves, aiming to increase the material it supplies for every tyre on the road.
- Pilot done, customers interested - pilot trials for recycled rubber have been completed and have received extremely positive feedback from customers, and a detailed commercial-scale project is now being actively worked on. The company is also exploring products derived from waste tyres, with sourcing both domestic and international.
- R&D is being rebuilt to feed the pipeline - a new R&D unit is being set up at the flagship facility with an investment of about ₹6 crore, aimed at introducing new products, increasing productivity, and deepening penetration in existing markets. The company is also developing value-added zinc chemicals for electronics, petroleum and environmental protection industries.
Group structure and partners
The company operates through a holding structure where the listed parent owns 94% of its most critical manufacturing subsidiary, and the entire group runs on a zero-debt balance sheet.
- Three existing plants, one under construction - the manufacturing footprint spans two West Bengal plants (Jangalpur and Belur) and the Naidupeta subsidiary plant, with a greenfield facility at Dahej, Gujarat, adding over 40,000 tonnes of capacity and marking the company’s entry into Western India, close to key customers and the ceramics industry.
- Promoter-held and institutionally backed - the promoters’ group held roughly 71% as of March 2024, and marquee institutional investors include the Massachusetts Institute of Technology, Pinebridge Global Funds, Carnelian Structural Shift Fund and SBI General Insurance. The company carries no debt, funding its Dahej project entirely through internal accruals.
