Zinc EDTA Manufacturing Plant Project Report 2026: Cost Analysis, ROI, and Feasibility Insights

The process starts by dissolving zinc sulfate in water and preparing an EDTA aqueous solution with a pH value of 6-7 using sodium hydroxide. The zinc sulfate solution is added to the EDTA solution at 60-70 degree Celsius with continuous stirring to form a Zn-EDTA complex, after which sulfuric acid is added to precipitate the product. The final product is obtained by filtering, washing, and drying the precipitate.

The main feedstocks are zinc sulfate, EDTA, sodium hydroxide, and sulfuric acid. EDTA accounts for around 50-60% of direct raw-material costs, zinc sulfate about 25-35%, sodium hydroxide around 5-10%, and sulfuric acid about 3-8%.

The major cost drivers are the prices of EDTA and zinc sulfate, which generally represent the largest portion of direct material expenditure. Other factors include sodium hydroxide and sulfuric acid consumption, energy requirements, reaction yield, filtration and drying costs, labor, maintenance, packaging, wastewater treatment, and logistics. Product purity and zinc content requirements can also affect the cost of raw materials and quality control. Commercial zinc EDTA products commonly specify controlled zinc content and limits for contaminants such as lead, cadmium, and arsenic.

Manufacturing requires appropriate controls for process wastewater, zinc-containing effluents, chemical handling, and gaseous emissions. Effluent treatment plants can be used to manage wastewater, while suitable ventilation and pollution-control systems help maintain workplace and environmental compliance. For agricultural-grade zinc EDTA, product standards may also specify minimum zinc content and limits for contaminants such as lead, cadmium, and arsenic. In India, IS 13921:2024 specifies a minimum 12% zinc content for Zn-EDTA and limits for these contaminants. Sustainability measures can include recovery of zinc from process streams, water recycling, minimizing EDTA and zinc losses, and improving energy efficiency during heating, filtration, and drying.
