    I used to to business with GM Saturn engine manufacturing. They mold engines using the "lost foam" method pioneered by the Aztecs to make gold figurines. (the Aztecs used wax, but the method is the same)

    They make a styrofoam mold of a block, a head, 4 or 6 cylinders. (Saturn engines)

    These molds are cast on a common stalk, then buried in sand in a huge kettle.

    Picture 4 foam engine blocks on a foam stalk, attached at all angles like brussel sprouts.

    Buried in the sand, everything that is not sand is shaped like an engine part. Then they pour molten aluminum onto the stalk. The foam flashes off under those temperatures, gets captured in the exhaust scrubbers.

    The spaces in the sand become exact replicas of the foam, in aluminum. Look closely at an unpainted Saturn engine, and you can see that it looks like a foam coffee cup.

    That's my aluminum story.

    Drive a few hundred miles in any direction, and the experience changes dramatically.

    Begger either you need to get back on your meds, or lay off the absinthe. You're not making sense.

    Too much aluminum exposure

    Recycle your aluminum and here is another reason why you should:
    Chances are, due to the global market, the origin of an appreciable portion of the aluminum you use everyday is from China. They produce 55% of the world's supply. They are getting massive government subsidies to maintain and further enhance their production, driving the cost down, and closing US production facilities.
    Their 3rd largest aluminum production facility produces more than all the smelters in the USA, combined. In fact, aluminum production in the USA is at its lowest point since the pre 1950 levels.
    While demand is up over 36% since 2009, US production is down 37% just from last year. Can't compete with China's government subsidies for their aluminum industry. Since 2007, With the market being flooded with Chinese aluminum, the price has dropped over a thousand dollars per ton.
    China uses coal for their energy to smelt aluminum. The Chinese government allocates billions of tons to support its aluminum industry. It is an inefficient use and unfriendly to their environment. Their aluminum manufacturing companies, operate annually losing billions, however the government subsidizes these companies, to keep them producing, in their worst economy in years, keeping millions employed.
    Since 2015, in the USA, 8 smelters have either closed or curtailed operations, including the nation's largest facility, Alcoa, in Warwick Indiana.
    Beer in bottles just tastes better.
    I am curious as to the origin of the aluminum used in the auto industry. F150 and the Cadillac CT series are examples that use aluminum bodies and frames.
    My understanding is that the Aluminum beer can you opened tonight watching a ball game was mainly RECYLCED aluminum from maybe 6 weeks ago.  
    As for some Aluminum Alloys?  Maybe 7000 series, I think they must be fabricated from raw materials and not 'recycle'.

    If you want to mitigate health issues through information based on collective science, just emulate the guidelines that the EU uses.  They are science based and common sense.  They have an agency called the EEA ( https://en.wikipedia.org/wiki/European_Environment_Agency) that is better than the US EPA/FDA insofar as our agencies are hamstrung by industry lobbyists and science denying idiots (you know who I'm talking about - like snowball man).
