Petro Carbon and Chemicals Ltd (PCCL) is a manufacturer that turns a waste byproduct of oil refining into a material the aluminium industry cannot make metal without. Born from a 70-year-old mining conglomerate and operating the same plant in Haldia since 2008, the company’s entire approach rests on a single idea: take a low-value input, apply intense heat, and sell a high-purity output to a handful of giant customers who have no substitute for it. # Business segments A single-engine business built around one plant, one process and one product - calcined petroleum coke - with a captive power unit that feeds the engine and an expansion pipeline that aims to add two more. ## 1. Calcined petroleum coke: the irreplaceable ingredient in aluminium smelting **PCCL bakes a refinery waste product into a high-purity carbon material that aluminium smelters have used for over 120 years and for which no commercially viable alternative exists.** - **The process is thermal upgrading** - Raw Petroleum Coke (RPC), a byproduct of oil refining, is heated in a rotary kiln at 1200°C to 1400°C to drive off impurities and moisture, leaving behind a hard, dense, almost pure carbon with the electrical conductivity needed to make carbon anodes for the Hall-Heroult smelting process. - **Aluminium is the anchor customer** - anode-grade CPC represents approximately more than 75% of global CPC production, which needs roughly 0.4 tonnes of CPC for every tonne of primary aluminium produced; the rest is sold as recarburizer to steelmakers and foundries, or to titanium dioxide manufacturers. - **The plant sits inside a port** - the single manufacturing facility, with a capacity of about 93,744 tonnes per annum, occupies roughly 30 acres within the Haldia Dock Complex in West Bengal, giving it direct access to highways, railways and the port that are critical because freight costs for both raw-material imports and finished-product dispatch make or break the business. - **Raw material is mostly imported** - more than 90% of RPC comes from foreign suppliers because the high-sulphur grade needed for aluminium-grade CPC is not available in sufficient quantity from domestic refineries; the company hedges 100% of its foreign-exchange exposure through a two-stage policy tied to letters of credit. - **Sales happen through tenders, not agents** - revenue comes from quarterly or regular tenders with large aluminium companies like NALCO and Hindalco, with marketing handled through direct contact from a centralised setup; in 2018 NALCO recognised PCCL as its top supplier among all petroleum, oil and lubricants vendors. ## 2. Captive power: turning waste heat into cheaper electricity **A 10 MW waste-heat recovery plant commissioned in March 2025 captures heat from the calcining kilns to generate electricity, cutting both the power bill and dependence on the grid.** - **Heat that was once lost now makes steam** - the Waste Heat Recovery Boiler plant uses exhaust heat from the calcining process to produce steam, which drives a turbine; in its first partial year it generated over 3.7 million kilowatt-hours of electricity and more than 15,000 metric tonnes of steam. - **Energy independence lowers the cost base** - by displacing grid power from the West Bengal State Electricity Distribution Company, the captive plant substantially reduces power costs for an operation where calcining is inherently energy-intensive. ## 3. Advanced carbon expansion: building a multi-product future on the same site **Environmental clearance received in April 2025 clears the way for three new plants - electrically calcined anthracite, coal-tar distillation and a revamped carbon-paste unit - that aim to break the company’s single-product dependence.** - **Three new product lines under one approval** - the Ministry of Environment clearance covers a 72,000-tonne-per-annum Electrically Calcined Anthracite plant, a 60,000-tonne-per-annum Coal Tar Distillation plant, and a 48,000-tonne-per-annum revamp of the old Carbon Paste Plant, all at the existing Haldia site. - **A deliberate move away from one-product risk** - the company has identified its single-product nature as a weakness and is using this expansion to enter adjacent carbon materials and chemicals, including exploring the carbon-based recycling industry and the potential future demand for CPC from lithium-ion battery component manufacturing in India. # Group structure and partners **PCCL sits inside the 70-year-old ATHA Group and has recently spun out two subsidiaries and a step-down partnership to stretch into neighbouring chemical markets.** - **ATHA Group is the parent** - founded in 1957 in Odisha as a mining and minerals company, the Kolkata-headquartered conglomerate now spans multiple products, technologies and locations. - **Two new wholly-owned subsidiaries** - ACL Advanced Materials Private Limited, incorporated in October 2024, will manufacture basic chemicals and petroleum products such as petroleum jelly, waxes and petroleum coke; ACL Alchemy Private Limited, incorporated in November 2024, will make coke-oven products including gas, crude coal and lignite tars. - **A step-down partnership for backward integration** - through ACL Alchemy, PCCL holds a 50% stake in Vishal Industries, a partnership firm effective April 2025 that manufactures calcined products, with the goal of strengthening backward integration in the carbon-chemicals space and opening access to newer markets.
