With so much happening in the world concerning climate change, we constantly desire to find more sustainable options to power our everyday amenities. But when it comes to our smartphones, the latest discovery in sustainable power sources may raise an eyebrow or two.

Researchers at the University of Colorado Boulder have made an unexpected discovery inspired by the beer breweries that are growing in popularity in the area. Surprisingly, the wastewater produced during the beer-brewing process helps grow a fungus, Neurospora crassa, that can be turned into critical components of lithium-ion batteries, used to power our smartphones and other personal electronics.

And since the wastewater has to be filtered (which is very expensive) before it can be thrown out, this is a much better option for the environment and beer-brewing companies (beer won’t be as pricey for consumers).

Though beer-brew wastewater-powered smartphone batteries aren’t hitting the market anytime soon, the excitement of them being launched in the near future does bring some much-needed optimism to the sustainability movement. In fact, researchers are already collaborating with Avery Brewing in Boulder with hopes for a pilot program to bring these sustainable smartphone batteries to a store near us sooner than we think.
