§1What this business is
The work has 2 stages. First coconut shells are carbonised into shell charcoal in pits, brick kilns or metal kilns. The charcoal is then activated by steam at 900°C–1100°C under a controlled atmosphere in a rotary kiln, which opens up fine pores inside each grain. Below 900°C the reaction is too slow; above 1100°C the charcoal burns away from the outside. The product is cooled, ground, sieved and packed. Shell-based carbon is valued for its small pores, which adsorb gases, colour and odour well. It is used in refining vegetable oils and chemicals, water purification, solvent recovery, gold recovery and gas masks.
Capacity: 5 tonnes a day.
§2Is it right for you?
Who it is for
An industrial investor in a coconut belt with access to shell charcoal, process engineers and export or industrial buyers.
Who it is not for
A first-time small entrepreneur, or anyone without assured charcoal supply and pollution clearances.
Advantages
- Shell-based carbon is rated above carbon from coal, wood or husk
- Many industrial buyers: water treatment, edible oil, chemicals, gold mining
- Turns a cheap farm by-product into a high-value export product
- Steam activation needs no chemical activating agent
Drawbacks
- Heavy outlay of ₹4.32 crore besides 2 acres of land
- The profile gives no sales or profit figures, so returns must be worked out afresh
- Kilns run at 900–1100°C and need skilled operators round the clock
- Needs a large, steady supply of good shell charcoal
Skills you need
- Rotary kiln and boiler operation
- Laboratory testing of adsorption, ash and moisture
- Bulk buying of shell charcoal
- Industrial and export marketing
Why difficulty 5/5: A capital-heavy, high-temperature process plant with strict quality and pollution demands.
§3Market
Who buys
- Water purification and treatment companies
- Vegetable oil refiners and chemical plants
- Gold recovery units and solvent recovery plants

§6Schemes & subsidies
At ₹4.32 crore the plant is far above PMEGP's ₹50 lakh ceiling. CGTMSE covers loans up to ₹10 crore without collateral for a micro or small enterprise. Ask the Coconut Development Board about assistance under its Technology Mission on Coconut.
§7Money
How the investment is worked out: Building of 12,000 sq ft at ₹600 per sq ft ₹72 lakh + plant and machinery ₹275 lakh + preliminary and pre-operative expenses ₹15 lakh + electrification ₹20 lakh + working capital margin ₹50 lakh = ₹432 lakh (₹4.32 crore). The profile prints these lines without a total; they are added here. Land of 2 acres is extra — the profile calls its cost variable.
Working capital: Working capital margin ₹50 lakh.

§8Export potential
Confirm the HS code in the DGFT ITC(HS) lookup before you export
Export council / board: Coconut Development Board
- The profile itself prints no HS code; 3802 is the customs heading for activated carbon.
§9Risks — where people fail
- Shell charcoal price and supply swings
- Product failing buyer specifications such as adsorption value or hardness
- Kiln breakdowns and fire hazards
- Dust and emission norms tightening
§1030 / 60 / 90-day plan
A general plan that applies to any business. A plan for this business will be added after research.
- Days 1–30: Visit a working coconut shell activated carbon plant unit, ask 10 buyers about price and quantity, and get quotations from 3 suppliers.
- Days 31–60: Udyam and the licences you need (Udyam registration, GST registration), a project report (DPR), and the scheme or loan file.
- Days 61–90: Space and machines, trial production, and first deliveries to 10 customers.
