This start-up is looking to space to make mining more sustainable

AstroForge is building a system for mining asteroids, focusing on 6 elements, known as the platinum group metals. Platinum group metals are used across many different industries, from electronics and pharmaceuticals to the microchips that power AI. But platinum mining on Earth can be environmentally challenging. On an asteroid, concentrations of platinum are about 5,000 times greater which - theoretically - should make mining them in space greener, even factoring in rocket fuel.
