Nano-Enabled Circular Economy Approaches for Restoring Oil Contaminated Ecosystems

Abstract

This study investigates the integration of nano-enabled technologies within circular economy strategies to remediate oil-contaminated ecosystems. By synthesizing current literature and empirical data from oil-impacted sites in the Absheron Peninsula, Azerbaijan, the study evaluates the efficiency, sustainability, and economic viability of nanomaterial-assisted remediation techniques. The study collated secondary data on soil contamination, application of nanomaterials, and waste management practices while comparative analysis was done for environmental and economic outcomes. The critical messages communicated are that deployment of nanotechnology with circularity such as waste valorization, resource recovery, and bio-based recycling enhances efficiency of hydrocarbon degradation by up to 85%, while the remediation cost is lower than that of conventional methods, and results in lower risks to the environment. The use of these approaches is strongly influenced by the policy and governance frameworks in place, with regulatory barriers and market readiness being cited as important. The researchers conclude that using circular strategies enabled by nanomaterials can help clean up soil contamination, as well as contribute to the goals of sustainable development. Further, it can be replicated in oil-producing regions around the world. To strengthen policy incentives, invest in nanotechnology research and incorporate circular economy indicators into environmental governance. This research contributes to knowledge by linking advanced nanomaterials with practical circular economy approaches, offering a novel framework for sustainable oil spill management.
