Population growth, excessive consumption, increased greenhouse gas emissions from industry and vehicles, continued use of fossil fuels, and inadequate implementation of climate policies are causing temperatures to rise above expectations. The increase in temperature brings with it many problems such as water scarcity, access to clean water, decrease in agricultural activities, food shortages, epidemics, the deterioration of the natural balance along with the decrease in the number of living creatures in the ecosystem. For this reason, it is inevitable that studies that will contribute to an environmentally friendly, sustainable and circular economy will emerge in every field. In this context, microalgae offer significant potential. Recently, carbon capture, wastewater treatment and obtaining high value-added products from biomass are seen as promising and innovative approaches with microalgae. Especially the use of wastewater as a growth medium for microalgae is very important in terms of resource recovery. Türkiye is one of the leading countries in olive and olive oil production. Olive mill wastewater generated during the production phase constitutes an important environmental problem. Due to the high COD, BOD, TN, TP, polyphenol content, oil, acidic pH and dark color found in olive mill wastewater, its direct discharge poses a great danger to the water and soil ecosystem. In this study, domestic olive mill wastewater prepared naturally at home was used and Chlorella variabilis type microalgae were studied. Samples with different dilution rates (0%, 5%, 15%, 20%) were prepared from domestic olive mill wastewater. COD, TN, TP, pH and growth values were measured for each sample. After 24 days of cultivation, the same parameters were measured again and the removal efficiencies were obtained as COD 72.71%, TN 77.51% and TP 89.44%, respectively. As a result, the treatability of domestic olive mill wastewater with microalgae emerges as an alternative, innovative, environmentally friendly, sustainable, and economical method compared to traditional methods.
