What's the difference between stainless steel, cast iron, non-stick, aluminum, hard-anodized productsAre they used in different types of cooking or something?? cheers
You need to look at the entire cycle of your process to determine efficiencyIt takes massive amounts of electricity to make aluminium - OK you are using recycle but energy is used to collect itThe cans are painted and lacquered - that will inhibit reactivity - how will you clean them up? It takes massive amounts of electricity to make sodium hydroxide - any environmental imact needs to take that into accountYou can buy 50lbs of NaOH for $35 - how much electricity can you buy for $35? In other words, what are the relative economics of buying the sodium hydroxide and aluminium scrap vs the cost of electricity to make the same amount of hydrogen? When you electrolise water you also get oxygen as a by-productThat too has valueAt the end of your process you will have large amounts of waste sodium aluminate solution - does it have commercial value? No? How will you dispose of it? Heavily contaminated with caustic soda that is a hazardous waste - disposal is ?$?$?$?$!
