The first step in aluminium recycling is the collection and sorting of aluminium scrap from various sources. [5] Scrap aluminium comes primarily from either manufacturing scrap or end-of-life aluminium products such as vehicles, building materials, and consumer products. [5]
This process does not produce any change in the metal, so aluminium can be recycled indefinitely. Recycling aluminium saves 96% of the energy cost of processing new aluminium, it also helps divert significant amounts of waste from landfills. [11] This is because the temperature necessary for melting recycled, nearly pure, aluminium is 600 °C ...
The most suitable materials for closed-loop recycling are aluminum and glass. These are known to maintain their quality throughout many cycles of extraction, production, use, and recycling. [5] For example, aluminum cans can be recycled and turned into new cans with practically no material degradation or waste. [citation needed]

Secondary production is the recycling of metallic aluminum derived from scrap. Secondary production can be from either new scrap (from aluminum manufacturing), or from old scrap (post-consumer scrap such as recycled aluminum cans). By 2021, secondary production accounted for 78% of US aluminum production. [17]
Recycling aluminum cans may not be the best way to become a millionaire, but it's certainly a great way to contribute to a greener lifestyle, and it can help you save each month.
All four can be made by high-temperature (and possibly high-pressure) direct reaction of their component elements. [52] Aluminium alloys well with most other metals (with the exception of most alkali metals and group 13 metals) and over 150 intermetallics with other metals are known.
Aluminium recycling is where pure aluminium products (previously used in another form) are re-melted into aluminium ingots and then re-used to new aluminium products. [9] While aluminium dross recycling is where the dross, a byproduct of the smelting process in the creation of aluminium from bauxite , can be mechanically recycled thus ...
