- **Deccan Cements is a four-decade-old south Indian cement maker that is in the final stage of completing an expansion that will double its production capacity to four million tonnes a year - a move that reshapes its future but not its identity.** Incorporated in Hyderabad in 1979, the company has spent its life making and selling cement in a handful of southern and eastern states, led for most of that time by a technocrat chairman with over 46 years in the industry. The recurring approach is an obsession with energy efficiency: the company consistently burns less power and less heat per tonne than the industry norm, and it feeds its own waste - fly ash, waste heat, even colony garbage - back into the production loop. # Business segments Two engines, one core - a cement business that is the company's reason for being, and a small power-generation side that exists to feed it and sell the surplus. ## 1. Cement: the main engine, now twice as large **A single-product manufacturer selling three types of cement across five states, running a plant so energy-efficient that it uses roughly a quarter less electricity per tonne than the industry average.** - **Cheaper to run than rivals** - in FY25, the plant consumed 75.33 KWH of electricity per tonne of cement against an industry norm of 100 KWH, and its kiln heat consumption was 745.63 K.Cal per kg of clinker against a norm of 800, which means lower power and fuel bills for every bag it sells. - **Waste feeds the process** - 100% of the fly ash and bottom ash from its own captive power plant goes into making Portland Pozzolana Cement (PPC), and the clinker factor (the proportion of clinker in cement) was 65.44% in FY25, so the company saves on limestone and coal by substituting ash. - **Rail-connected and self-contained** - the plant has its own railway siding for moving cement out and a wagon tippler for unloading coal in, which cuts logistics costs and keeps the factory fed without relying on third-party terminals. - **Doubled capacity in one leap** - after years of selling roughly 1.8 to 1.9 lakh tonnes a month from a 2.2 million-tonne-per-year base, the company commissioned a new Line-3 on 15 December 2025, taking total installed capacity to 4.00 million tonnes per annum at the same plant location. - **New limestone mines in the pipeline** - to secure raw material beyond its existing leases, the company won preferred-bidder status for a limestone block in Rajasthan (Rata Mandha-1A) and another in Telangana (Saidulnama Block), both now moving through statutory approvals. ## 2. Power generation: captive supply with a small surplus sold outside **A trio of waste-heat, hydel and wind plants that exist primarily to power the cement factory, with any leftover electricity sold to external customers.** - **Heat that would be wasted makes electricity** - a 7.0 MW Waste Heat Recovery plant captures hot gases from the cement kiln and cooler to generate power, so the company produces energy from a by-product it already has. - **Water and wind add clean megawatts** - a 3.75 MW hydel plant sits on the Nagarjunasagar Canal, and additional wind turbines contribute renewable generation, though the wind capacity is not separately disclosed in filings. - **Ash completes the loop** - the captive power plant's bottom ash and fly ash are entirely consumed in making PPC, so the power and cement operations form a closed resource circuit. # Group structure and partners **A family-controlled company with a single subsidiary created to build a future project in Rajasthan, and no joint ventures.** - **One subsidiary for a new geography** - Deccan Swarna Cements Private Limited was incorporated on 13 March 2024 as a wholly owned subsidiary to implement a project in Jaisalmer, Rajasthan, which is where the company secured its new limestone block. - **Promoters hold a stable majority** - the promoter group, including the late chairman's family and associated entities, held 56.19% of shares as of December 2022, with no foreign collaboration and only incidental foreign institutional holdings picked up through the secondary market. - **Lean board, recognised unions** - six directors (two executive, four independent) oversee the company, while about 6% of the 357 permanent employees belong to unions affiliated to TNTUC and INTUC, with a much larger temporary workforce of 683 contract and casual workers handling peak or project needs.
