Optimizing Citric Acid Production: A Comprehensive Cost Analysis
Citric acid is a naturally occurring weak organic acid found in citrus fruits, widely used for its sour taste, preservative properties, and acidity regulation. Industrially, it is produced through the fermentation of sugars and is a key ingredient in the food and beverage industry, where it enhances flavor and preserves freshness. Additionally, it has applications in pharmaceuticals, cosmetics, and cleaning products due to its ability to stabilize ingredients and chelate metals. According to an IMARC study, the global citric acid production market was 3.10 Million Tons in 2024, growing at a CAGR of 7.8% from 2019 to 2024. Looking ahead, the market is expected to grow at a CAGR of approximately 5.4% from 2025 to 2033, reaching a projected volume of 4.18 Million Tons by 2033. The growing demand for citric acid is driven by its versatile applications across various industries. In the food and beverage sector, it is widely used as a preservative and flavor enhancer, aligning with the increasing preference for natural additives. In pharmaceuticals, citric acid plays a critical role due to its antioxidant properties and ability to stabilize medications. The rise of eco-friendly cleaning products has also boosted its use as a safe, biodegradable alternative in household and industrial cleaners. Additionally, the expanding cosmetics industry uses citric acid in personal care products for pH regulation and exfoliation. Increasing health consciousness and a shift towards natural ingredients continue to fuel this demand.

Case Study on Cost Model of Citric Acid Manufacturing Plant
Objective: One of our clients has approached us to conduct a feasibility study for establishing a mid to large-scale citric acid manufacturing plant in KEZAD Free Zone, Abu Dhabi (UAE). We have developed a comprehensive financial model for the plant's setup and operations. The proposed facility is designed with an annual production capacity of 40,000 tons of citric acid and will cover a land area of 18,000 square meters.
Manufacturing Process: Citric acid is produced by fermentation, usually with the aid of Aspergillus niger and carbohydrates such as glucose, molasses, or starch hydrolysates. The feedstock is first sterilised, diluted, then nutrient supplemented. The fungal strain is scaled up for fermentation by inoculum preparation. In fermenters, the sterile feedstock is inoculated under controlled aerobic conditions. The pH and temperature are adjusted to maximise the generation of citric acid over a period of 5–10 days. Filtration or centrifugation are used to remove the fungal biomass from the broth following fermentation. After treating the citric acid-rich filtrate with lime, calcium citrate is precipitated. This calcium citrate then reacts with sulphuric acid to regenerate citric acid, with gypsum as a byproduct. Evaporation concentrates the citric acid solution, and cooling causes it to crystallise. The crystals undergo separation, drying, milling, and packaging to avoid contamination or moisture absorption. Throughout, quality control procedures are used to guarantee product purity and adherence to requirements. By using or disposing of by-products like gypsum and fungal biomass properly, the process is both environmentally sustainable and resource efficient.
Mass Balance and Raw Material Required: The primary raw materials utilized in the citric acid manufacturing plant include corn starch, enzyme, active carbon, calcium carbonate, sulfuric acid, hydrochloric acid, and sodium hydroxide. To produce 1 ton of citric acid, we require corn starch (0.9 ton), enzyme (glucoamylase) (0.003 ton), active carbon (0.0035 ton), calcium carbonate (0.8 ton), sulfuric acid (0.8 ton), hydrochloric acid (0.18 ton) and sodium hydroxide (0.08 ton).
Techno-Commercial Parameter:
- Capital Investment (CapEx): The total capital cost for establishing the proposed citric acid manufacturing plant is approximately US$ 28.12 Million. Machinery cost account for 57.6% of the total capital cost, while civil works costs are estimated at US$ 10.47 Million. The civil work cost for the citric acid manufacturing plant constitutes a significant portion of the total capital cost, construction of production buildings, storage facilities, wastewater treatment units, safety infrastructure, and administrative offices. The cost of land and site development is significantly low as compared to other involved costs. This ensures a robust foundation for safe and efficient plant operations.
- Operating Expenditure (OpEx): In a citric acid manufacturing plant, the operational cost for the first year of operations is projected at US$ 28.34 Million. This estimate includes the cost of raw materials, utilities, salaries and wages, transportation cost, overheads and all other costs. By the seventh year of operations, the total expenditure cost is expected to increase by 32.5% compared to the first year, driven by inflation, market fluctuations, and potential rises in the cost of key materials. Factors contributing to this increase include supply chain disruptions, growing market demand, and changes in global economic conditions.
- Profitability Analysis Year on Year Basis: The proposed citric acid plant, with a capacity of 40,000 tons per annum, achieved an impressive revenue of US$ 34.91 Million in its first year. We assisted our client in developing a detailed cost model, which projects steady growth, with revenue reaching US$ 47.38 Million by Year 7. Gross profit margins improve from 18.8% to 20.7%, and net profit margins rise from 11.5% to 16.5%, highlighting strong financial viability and operational efficiency.
Conclusion
Our financial model for the citric acid manufacturing plant was meticulously designed to meet the client’s objectives. It provided a thorough analysis of production costs, including raw materials, manufacturing processes, capital expenditure, and operational expenses. Tailored to the specific requirement of producing 40,000 tons of citric acid annually, the model highlights key cost drivers and forecasts profitability, considering market trends, inflation, and potential fluctuations in raw material prices. This comprehensive financial model offers the client valuable insights for strategic decision-making, demonstrating our commitment to delivering precise, client-focused solutions that ensure the long-term success of large-scale manufacturing projects.
