About Phoenix Tailings 

Phoenix Tailings is the world’s first clean mining and metals production company. Each year, the mining industry discards over 200 billion tons of waste (tailings) and produces more than 7% of the world’s carbon emissions. Using our proprietary novel technology, Phoenix Tailings eliminates this harmful waste from the environment and sustainably creates valuable new materials used in next-generation technologies.

The foundation of Phoenix Tailings emerged from a group of friends’ backyard conversations about fixing the broken system of metals production. Today, Phoenix Tailings is one of the top sustainability startups in the world, pioneering zero-waste mining. With funding from the US Department of Energy and National Science Foundation, Phoenix has made significant progress on our clean mining mission.
