How do we evolve?

• We need to explore new ways of doing things.

• We must move to a more sustainable economy where there is an extension in the use of resources.

What is BHP role?

Sustainability is one way road

In the last 15 years we have taken key steps to move to a

sustainable operation:

• Water: We stopped the water extraction from Monturaqui aquifer

and now we are 100% supplied from our desalinization plant.

• Power: by 2025 Spence and Escondida will be supplied with

100% of renewable power.

Our next step is focusing on waste management, introducing

technology and innovation in a collaborative approach to bring the

best of each one.

Contribute to a sustainable economy and bring people and

resources together to build a better word by transforming tailings

deposits into valuable materials
