Case Study on Cost Model of Stone Paper Manufacturing Plant

Objective: One of our clients has approached us to conduct a feasibility study for establishing a mid to large-scale stone paper manufacturing plant in Qatar. We have developed a detailed financial model for the plant's setup and operations. The proposed facility is designed with a production capacity of 16.67 tons per day, in a proposed land of 3,000 square meters.

Manufacturing Process: Stone paper production involves pelletizing and extrusion processes. It begins with internal mixing, where raw materials, auxiliaries, and additives are blended in a high-temperature, high-pressure kneader to ensure uniform dispersion. The mixed material is then granulated into pellets, making it suitable for extrusion. During extrusion, the granules are fed into an extruder with a screw and barrel system, where they are heated to 160°C and combined with molten PE. The molten material is then extruded through an O-shaped die, forming a cylindrical tube. Compressed air blows this into a stable film bubble, which is calendered through a three-roller system to achieve the desired thickness. Next, the material undergoes stretching and cooling for structural stability. Surface treatment, such as corona treatment, improves ink adhesion for printing. Slitting trims the edges to customer specifications, followed by coating for enhanced durability. Finally, the stone paper is wound into rolls for various applications.

Mass Balance and Raw Material Required: The primary raw materials utilized in the stone paper manufacturing plant include calcium carbonate, polyethylene (HDPE) and additive. To produce 1 ton of stone paper, we require 0.80 tons calcium carbonate, 0.18 tons polyethylene (HDPE) and 0.02 tons additive.

Techno-Commercial Parameter:

• Capital Investment (CapEx): The total capital cost for establishing the proposed stone paper manufacturing plant is approximately USD 6.37 Million. Civil works costs account for 44.8% of the total capital cost, while machinery costs are estimated at around USD 2.83 Million. The land and site development cost for stone paper manufacturing plant constitutes a significant portion of the total capital cost, including land registration charges, boundary development cost, and other development charges. This ensures a strong foundation for safe and efficient plant operations.
• Operating Expenditure (OpEx): In a stone paper manufacturing plant, the operating cost for the first year of operations is projected at USD 4.62 Million. This estimate includes the cost of raw materials, utilities, depreciation, taxes, packing cost, transportation cost, and repairs and maintenance. By the tenth year of operations, the total operational cost is expected to increase by 17.8% compared to the first year, driven by inflation, market fluctuations, and potential rises in the cost of key materials. Disruptions to the supply chain, rising consumer demand, and shifts in the state of the world economy are some of the factors causing this growth.

• Profitability Analysis Year on Year Basis: The proposed stone paper plant, with a capacity of 16.67 tons per day, achieved an impressive revenue of USD 6.00 Million in its first year. We assisted our client in developing a detailed cost model, which projects steady growth, with revenue reaching USD 7.60 Million by year 10. Gross profit margins improve from 23.0% to 28.4%, and net profit margins rise from 10.9% to 23.3%, highlighting strong financial viability and operational efficiency.
