Severino Becagli Spirulina grows in open ponds, called raceway ponds, inside computerized greenhouses, which allow for perfectly regulated temperatures, adequate aeration and sunlight exposure, while at the same time eliminating the risk of contamination of the final product. Raceway ponds have a special shape, designed according to hydrodynamic principles, so as to minimize areas of sedimentation. The harvesting is carried out without the need to handle the algae, thanks to complex innovative machinery which does not compromise the cells of the microalgae. The same machinery also transfers it to a building by the greenhouses. A “building inside a building” allows processing to be carried out in confined spaces, including 2 “clean rooms” for the filtration and desiccation rooms, which are temperature-controlled and air conditioned with Absolute HEPA filters, to make sure that all spaces meet ISO class 8 standards. The building also hosts a laboratory where the inocula for the Spirulina strains from the cultivation are kept active, and where cultivation in the greenhouses is monitored through microbiological and chemical check-ups and analyses.
