“…Using life cycle assessment (LCA), processes and products with a quantitative impact can be evaluated. Recent environmental awareness has led to LCA studies being conducted on a variety of products such as food, , chemicals, , coffee, , and pharmaceuticals. , In recent years, many researchers have published articles on LCA of various active pharmaceutical ingredients − and articles related to the comparative life cycle assessment of various chemical compounds. − A scale up framework has also been evaluated using LCA studies. − Sahu et al (2023) have carried out a LCA for the antisolvent crystallization for the selective salt recovery .

Methylcobalamin, the active form of vitamin B 12 , is a vital supplement for vitamin B 12 deficiency. Hydrotropic antisolvent crystallization was utilized for reducing methylcobalamin particle size as it offers advantages like enhancing the processing capacity, using solvents with low toxicity and low risk to human health. Recently, environmental awareness has fostered the use of life cycle assessment (LCA) for evaluating the environmental impacts of various processes. In the present study, a comparative study of the LCA approach has been adopted for producing methylcobalamin nanoparticles using hydrotropic antisolvent crystallization and antisolvent crystallization. In both processes, production of 1 mg of methylcobalamin nanoparticles was selected as a functional unit to conduct the impact assessment. SimaPro software was used to carry out the LCA study. The analysis has indicated that the centrifuging and washing, and drying stages have significant impact on the environmental categories under consideration. The incorporation of a hydrotrope in the antisolvent crystallization process has reduced the processing cost and environmental impact. The hydrotropic antisolvent crystallization is more sustainable as it lowers the environmental impact by ∼35% compared to antisolvent crystallization.

Diversifying energy sources and managing waste biomass are two pressing contemporary issues. The new technology proposed in this study aims to address both by converting waste biomass into energy and fertilizer through the use of a biofuel cell (BFC). The purpose of this study is to assess the environmental impacts associated with this innovative technology through a Life Cycle Assessment (LCA). To achieve the goal, the production and use of the cell were modelled, considering both laboratory-scale operations and industrial-scale approximations. The study explored alternative scenarios, such as sensitivity analyses involving different acids and bases, renewable energy sources, and heat recovery. Comparisons with conventional biomass waste treatments (anaerobic digestion and composting) demonstrated that the BFC technology remains competitive. To further improve the BFC’s environmental footprint, efforts should focus on reducing energy requirements and enhancing nutrient recovery during scale-up. These insights are crucial for advancing sustainable waste treatment technologies and maximizing the potential of discarded biomass in an environmentally friendly manner.
