§1What this business is
Selected spirulina strains are grown in tanks of water with fertilisers (NPK, superphosphate, magnesium sulphate) while paddle wheels keep the water moving so all cells get sunlight. The algae are harvested with fine filters, dried in a cross-flow tray dryer and ground to powder; it is mostly sold as capsules in bottles of 50 or 100. Dried spirulina has 60–70% protein. Buyers are health-food and supplement sellers, chemists and feed makers.
Capacity: About 200 MT of wet biomass a year, giving 10 MT of dried spirulina (cultivation 3 shifts, drying 1 shift).
§2Is it right for you?
Who it is for
A life-sciences graduate in a warm region with a health-food or chemist sales network.
Who it is not for
Someone in a cold area or without a way to sell capsules.

- Cultures can crash from contamination
- The two official profiles give very different profits
- Capsule sales need a brand and FSSAI supplement rules
