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.

Components of oily sludge contaminate the environment, disrupt the endocrine system, and are carcinogenic. Proper and complete treatment of the oily sludge followed by its safe disposal is essential to minimize environmental impact and protect human health. Existing treatment methods for oily sludge include incineration, landfilling, pyrolysis, and supercritical water oxidation; however, these techniques are energy-intensive, costly, and pose higher risks of environmental pollution. The present invention discloses a novel process for oily sludge degradation using a mild hydrothermal-assisted microalgae-based phycoremediation strategy. The method achieves 70– 75% degradation of long-chain aromatic and aliphatic hydrocarbons within 4–6 weeks. The degradation efficiency may further increase when the treatment period exceeds 6 weeks. Compared with conventional energy-intensive technologies for oil sludge treatment, the proposed method is more economical, environmentally sustainable, and suitable for long-term scale-up, with added potential for revenue generation.
