Biofuel production, particularly bio-jet fuel, has been incentivized due to the potential environmental benefits it can create. However, its production often relies on hydrogen from fossil sources, diminishing its sustainability. This work proposes a more sustainable alternative to the production of bio-jet fuel which involves generating hydrogen through the oxidation of metallic zinc in water, a safer and cleaner process. In this context, the study simulates bio-jet fuel production using non-fossil hydrogen from zinc oxidation. The process, modeled with Aspen Plus® V10, combines fatty acids and hydrogen to produce biokerosene, alongside zinc oxide, a commercially valuable byproduct. The proposed method operates under mild conditions (220 °C, 24 bar), reducing refinery dependence and offering economic advantages. The system was found to be economically viable with a 6-year investment payback and low CO2 emissions (4 kg CO2eq/kg H2), comparable to blue or turquoise hydrogen. Overall, this approach presents a sustainable and economically viable alternative for bio-jet fuel production, reducing the reliance on fossil sources and promoting greener aviation fuel.

Energetic materials release their chemical energy through slower exothermic reactions, as observed in propellants, or instantaneously, as with explosives. This narrative review provides a comprehensive and holistic perspective on the complex lifecycle of explosive solid waste (E-SW) and related energetic materials. It covers key aspects such as explosive waste research, definition, classification, history, applications, management complexities, environmental and health impacts, disposal methods, and green innovations. While explosives are critical in both civil and military applications, they pose significant environmental and health risks throughout their lifecycle. E-SW management remains an urgent yet underexplored area in scientific literature, especially compared to other explosive-related topics. Traditional disposal methods, like open burning and detonation, result in significant pollution, contaminating soil, water, and air. Despite this, these methods persist due to the lack of safer, economically viable alternatives. Innovative solutions such as biological treatments show promise in mitigating environmental damage, particularly in decontaminating metal residues for recycling. However, challenges in scalability and effectiveness remain. Prioritizing the development of biodegradable energetic materials and designing devices with safer dismantling procedures are essential. The pursuit of green innovations and further research is crucial to refining E-SW management strategies, reducing pollution, and protecting ecosystems and human health.
