Life cycle assessment of nanofiber production obtained by biomass nanospheres from microalgal

Microalgae are rapidly being employed in carbon fixation due to their benefits over other crops for energy needs, such as high photosynthetic efficiency, massive biomass production and rapid development. Spirulina maxima is a microalgae whose based on cultivation with favorable growing conditions. Within the Life Cycle Analysis, steps that fed into Impact 2002 system included assembly cultivation, characterization of nanochitosan, flocculation filtration, drying, nanosphere, obtaining filter. The stages were evaluated regarding environmental impacts could be caused. To evaluate these processes, Analysis (LCA) was applied using SimaPro software version 8.5 Ecoinvent 3 database “Impact 2002+” impact method from Swiss Federal Institute Technology. Characterization normalization data considered. categories stood out most relation release particulates atmosphere by carrying carcinogenic, non-carcinogenic, inorganic breathables, depletion ozone layer, organic global warming, non-renewable energy. category carcinogens (Kg C2H3Cl eq), there total 1.81 kg eq released particulates, non-carcinogens 3.91 Kg breathables have 0 0418 during stages, damage destruction expressed 1.35 E-6 divided between totaled 0.00771, warming CO2 we 24.1 within 352 MJ. As final result, after evaluating main risks present LCA process, “Damage human health”. result obtained consumption electricity.
