Dive Brief

Researchers in Colorado have found a way to use wastewater from brewing beer to produce lithium ion battery electrodes.

The researchers say using brewery wastewater could provide a more efficient and potentially cheaper source or materials for electrode production.

The University of Colorado-Boulder researchers have filed a patent on the process and created Emergy, a Boulder-based company aimed at commercializing the technology.
