In this imagined industrial world, heavy emitting industries have found a sustainable solution to their CO2 emissions. They have implemented a vertical closed photo bio reactor system consisting of 4 x 12 meters tanks to convert CO2 into microalgae biomass. These tanks are strategically placed in a central area, providing an aerial view of approximately 120 photo bio reactors connected to various industries. The purpose of this setup is to use the microalgae biomass for decarbonizing their operations. The reactors produce green microalgae, which can be utilized in different ways, such as biofuel production or as a source of nutritious supplements. This eco-friendly approach not only helps to reduce carbon emissions but also promotes the development of renewable resources within the industrial sector.
