There are closed systems of growing microalgae but as they are not able to produce algal biomass economically they are very few and far between and are only used to grow microalgae for very expensive produce. These closed systems also require large space. The result of the lack of economic closed systems is why almost all algal biomass production currently uses raceway ponds. This invention integrates a new compact, very economic and highly productive closed system of growing microalgae including good parameter control with carbon sequestration from say a coal fired power plant or organic waste management in a way that makes the whole process financially attractive and cyclic and if desired it could be made carbon negative. The compact nature of this invention allows algal farms to be sited next to most sources of carbon dioxide.

The present invention discloses a process mode of microalgal cultivation in semi- continuous on wine wastewater with no need to recirculate the microalgal biomass in the reactor, without dilution and sterilisation of the effluent applied as a growth medium. The process was experimentally carried out by semi-continuously applying, without recirculation of the biomass, the cultivation of Chlorella vulgaris on the digestate from the anaerobic co-digestion of winemaking lees and waste activated sludge. The integrated anaerobic digestion-microalgae treatment process is advantageous from a circular economy perspective as it leads to the exploitation of grape processing chain waste, eliminating the economic burden on producers and involving: i) the phyto-depuration of the effluent, ii) the production of bio- methane and iii) the production of biomass containing high value-added by-products (lipids, proteins and starch) that can be used to produce biodiesel, animal feed, nutraceuticals/pharmaceuticals and for producing bioplastics.
