摘要

The escalating demand for sustainable energy alternatives has prompted the development of innovative strategies that integrate renewable resources with advanced waste management methodologies. This analysis investigates the transformative capacity of employing high-level nuclear waste, which constitutes an estimated 370,000 metric tons worldwide, in the synthesis of biodiesel. Such waste comprises essential isotopes including Cesium-137, Strontium-90, and Plutonium-239, which, notwithstanding their protracted half-lives and associated environmental hazards, present unexplored thermal and radiative energy reservoirs. By leveraging the thermal energy resulting from radioactive decay—potentially surpassing 300 °C—and utilizing gamma radiation, which can accelerate chemical reaction rates by as much as 15%, this pioneering methodology could considerably diminish the energy requirements for biodiesel production from non-edible feedstocks such as Jatropha, Pongamia, and Phoenix sylvestris. Initial investigations indicate that the incorporation of nuclear waste management within biodiesel production processes could lead to a reduction in greenhouse gas (GHG) emissions by as much as 50% in comparison to traditional approaches, thereby offering a dual advantage of energy efficacy and waste reduction. This review emphasizes the imperative for further inquiry to optimize radioactive catalysts and heat recovery systems, with the goal of establishing a scalable, economically feasible framework for diminishing the environmental impact of both nuclear waste and biodiesel generation.
