These absolute concentrations are rather lower than most metals, so platinum in often a by-product of another mined resource such as nickel or coal. |
| − | + | There is an '''urgency''' to find a way to produce it '''sustainably''' before '''2064''', its exhaustion date. It's probably better to think about '''how to change the economic pathway''' of platinum than to try to find an alternative metal to platinum since the only substiture to platinum, palladium has its reserves more depleted than the paltinum ones and should be exhausted in '''2024'''. | |

Instead of being wasted in the environment, platinum can re-enter the economy. | + | The process we’ve designed allows the shaping of a circularized economy. Instead of being wasted in the environment, platinum can re-enter the economy thus making platinum production sustainable.! |
