Tony Pfaff,  geologist and founder of Unpollute Pty Ltd, has spent years working in the natural resources sector for environmental, geological, and geotechnical businesses. As mineral exploration becomes more costly with diminishing returns, it makes sense to return to old sites to recover those minerals which lead to pollution.

By addressing the Source-Pathway-Receptor (SPR) issue – a foundational concept in environmental remediation – we can do the right thing by the environment, and also contribute to the energy transition by recovering critical minerals.

After all, everything that is not waste is an asset.
