About Phoenix Tailings

Each year the mining industry discards over 200 billion tons of waste (tailings) and produces more than 7% of the world’s carbon emissions. Phoenix Tailings is on a mission to be the world’s first clean mining and metals production company. By eliminating this harmful waste from the environment, we can sustainably create valuable new materials.

We started with the humble beginnings of a few friends in a backyard, thinking of how they can fix this broken system of metals production. Now, Phoenix Tailings has become one of the top sustainability startups in the world. A Techstars Boston 2020 company with funding from the US Department of Energy and National Science Foundation, Phoenix has demonstrated early success in our clean mining mission. 

We still have a long way to go to achieve this mission. However, it’s our belief that together, the right people can overcome any obstacle and change the world.

Why Phoenix Tailings

At Phoenix, we believe that nothing great is ever accomplished alone or without the passion of people who push and motivate one another. If you are someone who shares our relentless pursuit of a better future, passion for innovation, and are excited about working with some of the top innovators in the world, then this is the place for you.

  • You are only crazy if you are wrong
  • It’s ok to be wrong
  • Lead with Compassion
  • Be Resourceful
  • Listen
  • Hustle
