    Aluminium recycling is the process in which secondary commercial aluminium is created from scrap or other forms of end-of-life or otherwise unusable aluminium. [1] It involves re-melting the metal, which is cheaper and more energy-efficient than the production of virgin aluminium by electrolysis of alumina (Al 2 O 3 ) refined from raw bauxite ...

  3. Closed-loop recycling - Wikipedia

    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]

  4. Galling - Wikipedia

    en.wikipedia.org/wiki/Galling

    Aluminium is a ductile metal, which means it possesses the ability for plastic flow with relative ease, presupposing a relatively consistent and significant plastic zone. High ductility and flowing material can be considered a general prerequisite for excessive material transfer and galling because frictional heating is closely linked to the ...

  5. Recycling by material - Wikipedia

    en.wikipedia.org/wiki/Recycling_by_material

    Recycling is via a steelworks: scrap is either remelted in an electric arc furnace (90-100% scrap), or used as part of the charge in a Basic Oxygen Furnace (around 25% scrap). [20] Any grade of steel can be recycled to top quality new metal, with no 'downgrading' from prime to lower quality materials as steel is recycled repeatedly. 42% of ...

    Reuse of. boxes and other containers has been common for many years. For example, the automotive industry has long used reusable racks, totes, and boxes. [4] One type of “closed loop box reuse” was used by Jack D. and James F. Wilson, coinventors of supportive devices developed to keep cardboard box flaps closed or held open without the use of tape.
