| Abstract | The search for natural raw materials rich in biologically active and harmless substances for the pharmaceutical, cosmetics and food industries is extremely significant nowadays, when modern life is characterized by numerous ecological problems. Microalgae are an untraditional but promising means to obtain the above purpose owing to possibilities to control, optimize and run large-scale production of useful and healthy biomass. The quality and economic efficiency of this production is site specific and highly dependent on climate, environmental conditions, developed know-how technology, as well as the existing local tradition of its use. The application of thermal waters, geothermal energy and carbon dioxide for microalgae cultivation provides high process optimization and considerably reduces the production costs. The article deals with the existing experience in Bulgaria for more than 35 years in terms of geothermal resource, cultivation, production and application of microalgae products. Special attention is paid to the economic efficiency of its cultivation. |
