The maximum pressure for an aerosol can is typically 10 bar (145 psi) at 20 C (68 F). Therefore, a fully compressed air duster will exhaust air about 10 times the can volume.

Glass, by contrast, is made from the more easily accessible silica. As a result of bauxite mining's environmental toll, manufacturing a 12-ounce aluminum can is twice as energy-intensive as making a similarly sized glass bottle: 2.07 kilowatt hours of electricity for the can vs. 1.09 kilowatt hours for the bottle.”
