Why Petcoke Has Always Been the Cement Industry’s Fuel of Choice

Petroleum coke, more commonly referred to as petcoke, was the predominant fuel for cement production for a few reasons: it is extremely high in calorific value and can be burned efficiently in rotary ovens and, for a large portion of the past two decades, it was economically priced when compared with coal.

In the clinkerisation process — which is the process that consumes the most energy in cement production, where material is heated up to high temperatures in order to create cement clinker. Petcoke ensures consistent, high-temperature combustion, which is hard to duplicate cheaply. In addition, cement plant operators running in-house thermal power plants have discovered petcoke to be an efficient and economical choice.

The industry was in a way dependent on petcoke and there was no need to diversify.

The West Asia Conflict and Its Ripple Effect on Fuel Markets

The current conflict within West Asia has significantly disrupted supply chains for energy around the world. The closing of the Strait of Hormuz — one of the crucial oil transport route — has caused a tightening of global markets for fuel. The rating agency ICRA predicts for crude prices would average around $95 per barrel for FY27, as opposed to $72 per barrel for the year ending in FY26. The sharp increase in the cost of crude is directly pushing up petcoke prices, that is the byproduct of refinery of crude oil.

The effects are already evident. Prices for Petcoke rose 19% monthly for April 2026 in a single month. Diesel prices likewise increased to Rs3.9 per litre from May 2026. This increased transportation and logistics costs as well as fuel costs. For cement plant owners it’s a double blow the fuel used for kilns is costly, as is fuel for trucks that move products and raw materials can be expensive as well.

So long as the geopolitical issue remains unclear, the soaring rates are predicted to last throughout FY27, and perhaps even beyond.

The Real Cost Impact on Cement Plant Operations

The figures tell a dramatic picture. Fuel and power costs together with sales costs combined, account for 50 % to 55% of the total operating expenses in a normal cement facility. ICRA estimates that the cost of power and fuel are expected to increase 10 to 12% during the fiscal year ending in. In conjunction with an increase of 6-8 percent increase in sales costs caused by increased freight and packing costs, the impact on margins is significant.

ICRA’s forecasts indicate that the operating profit per tonne for cement businesses is expected to fall between 10 and 15% by FY27falling from of Rs950-980 per tonne during FY26, to approximately Rs820-870 for FY27.

Companies that manufacture cement can shift some of the cost on to their customers by way of prices that increase. Some industry players have initiated price hikes ranging from around Rs10-12 per bag as of April 2026. The prices are anticipated to increase up to 3 to 5 percent throughout the course of the time. The intense competition on the market implies that a complete cost transfer is likely. Much of the costs will need to be handled internally, thereby making efficiency in operational fuel use and the use of alternative fuels an essential business priority.

• Industrial & Agricultural Waste Fuels
  Industrial and agricultural waste fuels such as bagasse, rice husks, and biomass are being widely adopted as alternative fuel sources in cement plants. They offer lower fuel costs, moderate calorific value, and are most effective near processing clusters.
• Refuse-Derived Fuel (RDF)
  Refuse-Derived Fuel (RDF), produced from municipal solid waste, is becoming increasingly popular in the cement industry. It helps reduce fossil fuel dependency while also supporting efficient waste management practices.
• Natural Gas & Hydrogen Blending
  Natural gas and hydrogen blending is emerging as a long-term sustainable fuel strategy for cement manufacturers. Although it provides flexibility and cleaner energy use, it requires major infrastructure upgrades.
• Coal Blending Strategies
  Coal blending strategies involve mixing petcoke with low-grade coal to reduce overall fuel costs without major equipment modifications. Effective implementation depends on precise process control and monitoring.
• Gradual Multi-Fuel Transition
  A gradual multi-fuel transition approach helps cement plants reduce petcoke dependency step-by-step. This strategy ensures smoother operations, stable kiln performance, and lower operational risks during fuel transition.

How to Achieve Alternative Fuel Transition Smoothly

Moving to alternative fuels is an intricate process that needs meticulous plan. If you rush the transition without doing an analysis of the engineering process could lead to unstable kilns, quality of clinker problems, as well as costly interruptions.

An effective transition usually starts with a comprehensive character study of the fuel that reveals the calorific content and moisture content, as well as the ash content, as well as the characteristics of combustion for the alternative fuel. It is then followed by a the evaluation of the burner system to find out the ability of existing burners to cope with the new mix of fuels or require modifications.

The process engineering industry plays a major function in this. Certain parameters such as the flame’s form, temperature profile and the distribution of heat in the kiln need to be revised in the event of a change in fuel composition. Kiln operators should also receive well-structured training for managing the changing combustion dynamics in a safe manner.

An approach that is phased beginning with a 10-to-15 percent substitution rate, and gradually growing as data on performance is collected — lowers risks significantly. Facilities should also undertake a thorough technical review prior to making the switch to find any electrical or mechanical constraints that may limit the flexibility of fuel.

Final Thought

The spike in petcoke prices of FY27 has been a clear indication that cement facilities cannot afford to be dependent on just one fuel source. The cost of crude-linked fuels is expected to stay high and competitive pressures limiting price transfer and fuel diversification, it is not merely a futuristic goal, but an operational need.

Facilities that are investing now in multi-fuel capabilities as well as process optimization and other engineering-driven changes will be better positioned safeguard margins, guarantee continuous operation, and develop the capacity to withstand long-term market fluctuation.
