Currently, research on algae focuses mostly on their application as a sustainable source of fuel. However, certain algae can be used to serve high-end markets such as the specialty food segment. Cyanidioschyzon merolae is an example of an algae species that can be used as a source of natural blue colorant. This research studies the cultivation of Cyanidioschyzon merolae in the tropics, using sunlight as a source of light and heat. A new reactor type is proposed which does not require degassing stations and has a high Surface Area to Volume ratio. Furthermore, a process design is proposed for the harvesting and filling of the specific reactors. A separate design is created of a comparable cultivation process in greenhouses. The outcome of the comparison of the two cultivation processes is a production price reduction of 20.87% in tropical cultivation, mainly as a result of a 86.72% reduction in energy requirements for utilities. However, even with the reduced cost price, these algae are not feasible for the production of natural blue colorant due to the height of the costs.
