Due to their properties, silver nanoparticles (AgNPs) are widely used in consumer products. The widespread use of these products leads to the release of such nanoparticles into the environment, during manufacturing, use, and disposal stages. Currently there is a high margin of uncertainty about the impacts of nano products on the environment and human health. Therefore, different approaches including life cycle assessment (LCA) are being used to evaluate the environmental and health impacts of these products. In this paper, a comparison between four different AgNP synthesis methods was conducted. In addition, four textile products that contain AgNPs were subjected to comparison using LCA analysis to assess their environmental and public health impacts using SimaPro modeling platform. Study results indicate that using alternative methods (green) to AgNPs synthesis will not necessarily reduce the environmental impacts of the synthesizing process. To the best of our knowledge, this is the first study that has compared and assessed the environmental burdens associated with different nanosilver-based textile products at different disposal scenarios. The synthesis of 1 kg of AgNPs using modified Tollens’ method resulted in 580 kg CO2 eq, while 531 kg CO2 eq resulted from the chemical approach. Furthermore, the manufacturing stage had the highest overall impacts as compared to other processes during the life cycle of the product, while the product utilization and disposal stages had the highest impacts on ecotoxicity. Sensitivity analysis revealed that under the two disposal scenarios of incineration and landfilling, the impacts were sensitive to the amount of AgNPs.

Abstract This paper evaluates the impacts of nuclear ammonia synthesis options on the environment through the life cycle assessment (LCA) technique. Ammonia is synthesized via the mature Haber–Bosch technique that combines hydrogen and nitrogen with 3:1 ratio to yield ammonia. For hydrogen production from water, five different hydrogen production methods are used, namely, conventional electrolysis (CE), high-temperature electrolysis (HTE), and 3-, 4-, and 5-step Cu–Cl cycles. The nitrogen required for ammonia synthesis is extracted from the air by the cryogenic air separation technique. The thermal and electrical energy need of production processes is supplied from a pressurized water reactor type nuclear power plant (NPP). The simapro software is utilized for LCA in the present study. The environmental impacts of nuclear ammonia are investigated through five impact categories, namely, abiotic depletion potential, acidification potential, global warming potential (GWP), ozone depletion potential, and human toxicity potential. According to LCA results, ammonia synthesis via HTE corresponds to the lowest environmental impact in all selected impact categories. Furthermore, the GWP for ammonia production via HTE is 0.1832 kg CO2 eq/kg ammonia, followed by CE (0.2240 kg CO2 eq/kg ammonia), 4-step Cu–Cl (0.3113 kg CO2 eq/kg ammonia), 3-step Cu–Cl (0.3323 kg CO2 eq/kg ammonia), and 5-step Cu–Cl (0.3370 kg CO2 eq/kg ammonia).
