ABSTRACT
This study is dedicated to realization closed biotechnology using Chlorella sorokiniana microalgae. It is a new source of valuable components for various kinds of industry and for obtaining energy such as biofuel and biogas. This technology includes several main stages: microalgae cultivation; extraction of lipids, pigments, pectic substances and carotenoids from the biomass; creation sorption materials based on residual biomass of microalgae for water treatment; using residual biomass and saturated sorbents as a fuel, as a co-substrate for organic waste fermentation and as fertilizers. It is shown that the realization of presented biotechnology allows to use each product on every step of the technology.
