چکیده
Abstract Purpose The study aimed to identify the environmental hotspots of lab-scale preparation high purity porous Al 2 O 3 pellets with suitable feature work properly as metal layer-based deposition substrates for hydrogen separation membranes. intention was providing hints that may help designing upscaled systems, fundamental development a possible future industrial production membranes technology. Methods goal this achieved assessing and analyzing impacts pellet at lab scale. Primary data were collected in Padua laboratories National Research Council Italy. Secondary retrieved from Ecoinvent 3.7 database. Life cycle assessment (LCA) performed using Environmental Footprint 3.0 method employing SimaPro 9.3 software. Moreover, CML LCIA v. 4.7 used verify robustness analysis characterized results. Results impact highlighted main driver mainly associated consolidation process their morphological characterization stage. In particular, first energy consuming resulted strictly related peculiar mix (linked laboratory geographical location). Conversely, stage found affect mineral resource depletion category due Au coating performing scanning electron microscope (SEM) analyses. Conclusions identified alumina substrate optimization strategies evaluated addressed improve profile experimental activities considering several scenarios, view scale-up.
