Setting up a liquid carbon dioxide production plant in India presents a compelling investment case for entrepreneurs seeking exposure to a versatile industrial gas sector. Demand is driven by industrial gas production, beverage carbonation, chemical processing, food processing, and renewable energy industries. Because liquid CO₂ is non-toxic, non-reactive, and suited to food-grade, medical-grade, and industrial-grade applications, this production is critical to India’s food and beverage, healthcare, and industrial gas economy.
India’s expanding cold chain infrastructure, growing non-alcoholic beverages market, and rising industrial gas demand make the country a strategically sound base. As per the Ministry of Food Processing, India’s non-alcoholic beverages market was valued at USD 30,846.6 Million in 2023 and is projected to reach USD 64,248.9 Million by 2033, strengthening demand for carbonation-grade liquid CO₂. Recent domestic capacity additions further reinforce why India suits this venture.
This investment case rests on stricter environmental regulations promoting CO₂ purification and liquefaction infrastructure, cost-competitive access to industrial waste CO2 and purification media feedstock, and consistent demand from food and beverage, healthcare, and oil and gas sectors. With gross profit margins of 35-45% and net profit margins of 18-28%, the project demonstrates a viable path to break-even and long-term profitability across a range of plant capacities.
What is Liquid Carbon Dioxide?
Liquid carbon dioxide (CO₂) is a colorless, odorless, non-flammable, and chemically stable cryogenic fluid produced by compressing and cooling carbon dioxide gas below its critical temperature and pressure. It is stored and transported at high pressure in insulated tanks to maintain its liquid state. Liquid CO₂ possesses high density, rapid vaporization, and excellent cooling efficiency, making it suitable for refrigeration, carbonation, freezing, and inerting applications, and is commonly recovered as a by-product from ammonia plants, hydrogen units, ethanol fermentation, and natural gas processing.
The liquid carbon dioxide production process relies on scrubbing/purification, compression, and liquefaction as its core production stages. The end products serve industrial gas production, beverage carbonation, chemical processing, food processing, and renewable energy industries.
Cost of Setting Up a Liquid Carbon Dioxide Production Plant in India
The total cost of setting up the facility depends on capacity, technology, location, automation level, and regulatory compliance.
1. Capital Expenditure (CapEx)
Capital investment covers land acquisition, site preparation, and infrastructure, and can be planned around an industrial estate or SEZ location. Civil works costs cover the processing shed, laboratory, storage areas, and administrative block. Machinery costs account for the largest portion of total capital expenditure, and equipment must be corrosion-resistant and tailored for this operation.
Key machinery required includes:
- Compression systems
- Purification units
- Liquefaction trains
- Cryogenic storage tanks
- Vaporizers
- Cylinder filling stations
Other capital costs include land registration, boundary development charges, pre-operative expenses, and commissioning costs.

2. Operational Expenditure (OpEx)
Raw material cost is the largest component of operating expenditure, with industrial waste CO2 and purification media together accounting for approximately 30-40% of OpEx. Long-term supplier contracts are recommended to mitigate feedstock price volatility.
Utility costs, covering electricity, water, and steam, account for approximately 45-55% of OpEx. Other operating costs include transportation, packaging, salaries, maintenance, depreciation, and taxes, which rise by the fifth year due to inflation.
3. Plant Capacity
The proposed unit is designed with an annual production capacity of 50-200 Million Nm³, enabling economies of scale while maintaining operational flexibility. Capacity can be customized per investor requirements, and profitability improves with higher utilisation.
4. Profit Margins and Financial Projections
Financial projections cover capital investment, operating costs, capacity utilisation, pricing trends, and demand outlook, including NPV, IRR, and payback period. Gross profit margins typically range between 35-45%, while net margins range between 18-28%.
Why Set Up a Liquid Carbon Dioxide Plant in India?
Growing Demand from Food Processing Sector. The increasing global consumption of packaged foods and carbonated beverages is creating consistent demand for food-grade liquid CO₂, particularly in freezing, chilling, and carbonation operations.

Strategic Importance in Energy and Oil Recovery. CO₂-based enhanced oil recovery remains a technically proven method to improve extraction efficiency, sustaining demand in oil-producing regions.
Expansion of Cold Chain Infrastructure. Growth in temperature-controlled logistics for pharmaceuticals and perishable goods is increasing demand for reliable cryogenic cooling agents such as liquid CO₂.
Active Industry Investment. In September 2025, Rashtriya Chemicals & Fertilizers Limited (RCF) started commercial operations of a new liquid carbon dioxide plant at its Trombay Unit, with a production capacity of 100 metric tons per day. In January 2025, Alto Ingredients’ subsidiary Alto Carbonic, LLC acquired Kodiak Carbonic, LLC, a beverage-grade liquid CO2 processor, for USD 7.25 Million.
Industrial Versatility. The product’s wide applicability across food and beverage, healthcare, manufacturing, and oil and gas sectors reduces dependency on a single industry, supporting stable long-term market prospects.
Production Process – Step by Step
The liquid carbon dioxide production process uses scrubbing/purification, compression, and liquefaction as the primary production method.
- Scrubbing/Purification: Raw industrial waste CO2 is treated using purification units to remove impurities and achieve the required purity.
- Compression: Purified CO2 gas is processed through compression systems to raise its pressure.
- Liquefaction: Compressed gas is cooled below its critical temperature within liquefaction trains to convert it into liquid form.
- Storage: Liquid CO₂ is held under high pressure in cryogenic storage tanks to maintain its liquid state.
- Vaporization Control: Vaporizers manage controlled release of the product where required for downstream use.
- Filling and Packaging: Finished liquid CO₂ is filled and packaged for dispatch to end-use industries.
Key Applications
