🌎 Good morning and happy Earth Day!
Cleaner aluminum?

This Earth Day, here’s something a bit different, with an Apple hook.

Green aluminum:

  • An interesting Bloomberg Businessweek story explains how, with some help from Apple, rival aluminum makers have teamed up to try to smelt the metal without producing any direct carbon pollutants.
  • Why Apple? The company is estimated to use 15,000 metric tons of aluminum annually for its device, and like many businesses, seeks to reduce its carbon footprint.
  • Apple generated some 22.6 million metric tons of carbon dioxide in 2020, per its own report, and references its work with aluminum and Elysis, the Canadian company created to disrupt aluminum production.
  • It’s estimated the aluminum sector accounts for almost 3% of global emissions.


  • Aluminum is sometimes called “solid electricity”, due to the huge amount of power used to smelt alumina. 
  • Smelters are located in hydropower-rich regions, and increasingly use renewable energy. (I worked on a project at one in Australia that was shut down due to unsustainable electricity prices versus aluminum prices).
  • The process of smelting, though, generates enormous emissions. 
  • Bloomberg quotes a research group saying “for every ton of aluminum produced, as much as 11 tons of carbon dioxide are emitted.”

Anyway, the story goes that Apple prodded two smelting rivals, Rio Tinto and Alcoa, working on innovations to decarbonize the smelting process, to join forces. They did so under the name Elysis. 

And here’s where it gets interesting, via the Businessweek piece:

  • “The result [of collaboration] was the creation of Elysis, a joint venture between Alcoa and Rio Tinto with investments from Apple, the government of Canada, and the provincial government of Quebec, which is one of the biggest aluminum-producing regions in the world. 
  • “The venture has developed a technology that makes so-called green aluminum, whose production doesn’t emit carbon dioxide. If the partners can make the process work at commercial scale, it could be used to retrofit existing smelters, transforming them from some of the dirtiest industrial polluters into the kind of green manufacturing facilities business and government are shifting toward.

  • “We use noncarbon materials that do not react, and as a consequence you get the separation of aluminum on the one side and oxygen on the other,” says [Vincent] Christ from Rio Tinto, who’s spent 36 years working to create carbonless aluminum. “It’s absolutely magic how we do that, but the explanation is very simple, actually.”

Now, it’s a little greenwashy to say that aluminum will become a green manufacturing business:

  • It will still consume huge amounts of energy and materials, even if renewables become larger portions of the mix. 
  • Recycling will always be better than needing to mine bauxite ore. 
  • But this would be an enormous improvement, if it can reach commercialization.

Winamp was released April 21st back in 1997, making the MP3 media player 23 years old yesterday.

Initially, Winamp was freeware, but in January 1998, it was switched to shareware, where for $10, people would get absolutely nothing more. But, per Wikipedia, “Winamp’s popularity and warm reception brought Nullsoft $100,000 a month that year from $10 paper checks in the mail from paying users”

It was in March 1998 that the famous Demo.mp3 file was included, with the words “Winamp, it really whips the llama’s ass”

Founders Justin Frankel (who was 18 years old for the first release of Winamp) and Dmitry Boldyrev sold Nullsoft, which developed Winamp, for a cool $80M to AOL, where by 2001, it had 60 million users. The original Nullsoft team had left by 2004. 

Winamp still exists now — Belgian online radio aggregator Radionomy bought Nullsoft, the company that developed Winamp, and through various wranglings, the last major release was Winamp 5.8 back in 2018, on
