Newly developed closed ecological cycle for solving environmental problems and obtaining high-quality biofuels
Abstract: Stagnant "green" zones of freshwater lakes, resulting from the excessive reproduction of phytoplankton in sunlit, stagnant waters, present a grave environmental hazard by causing the demise of phytoplankton and fish, and releasing hydrogen sulfide, rendering the water unsuitable for agricultural purposes. In this regard, the development of a closed ecological cycle, including the concentration of phytoplankton from the "green water" of the lake, which allows using most of the phytoplanktonconcentrate …
