With rising concerns over plastic pollution and climate change, microalgae-based bioplastics offer a promising alternative to petroleum-derived plastics. This study explores the dual role of Chlorella vulgaris in bioplastic synthesis environmental remediation through its cultivation wastewater-fed bioreactor. By leveraging wastewater as nutrient source, C. achieved biomass yield 3.472 g/L, with 20 mg/L polyhydroxyalkanoate (PHA) extracted. Fourier Transform Infrared (FTIR) spectroscopy validated presence PHA-specific ester functional groups, confirming suitability for applications. Additionally, process resulted complete reduction free CO2 within three days, demonstrating efficient carbon sequestration. Significant declines contaminants, including COD, BOD, nitrogen, phosphorus, highlight microalga's bioremediation capabilities, making it candidate sustainable treatment. introduces cost-efficient, self-sustaining microalgal bioprocess that eliminates need synthetic nutrients while achieving high-yield PHA production, sequestration, detoxification. integrating essential sustainability goals- capture, water purification- this work bridges gap between bio-based materials conservation. The results affirm multifunctional bioresource supports both biopolymer change mitigation. advances biotechnology by potential large-scale, closed-loop biomanufacturing, providing an eco-friendly, scalable solution reducing waste greenhouse gas emissions promoting industrial practices.
