Sustainable refinery waste management through biotechnological interventions: Health impacts, historical successes,...

In today's highly competitive and interconnected global market, economic achievement and prosperity are essential needs for every individual. However, in recent years, the "science of sustainability" has gained popularity due to mounting evidence of the damaging impacts of environmental issues. Lately, the expansion of petroleum industries and refineries has led to a substantial rise in the production of refinery oily waste. The treatment of such waste presents significant environmental challenges, necessitating the development of sustainable solutions. This review explores the latest advancements in biological processes for treating it, focusing on their efficacy and limitations. These processes are still facing challenges such as slow degradation rates, nutrient availability, and pollutant toxicity, which can hinder efficiency. To address these, efforts are being made to develop more viable biological treatments including exploration of microbial strains, optimizing process conditions, bioreactor systems, and integrating advanced bioremediation techniques. Potential applications of these processes across different contaminated sites are discussed along with commercially available technologies. Drawbacks related to bioprocess scale-up, cost-effectiveness, and regulatory constraints are also addressed. Additionally, it incorporates pertinent case studies that serve as illustrations of successful implementations of biological strategies. Ultimately, this sets the stage for practical bioremediation implementation as a solution for refinery waste management.
