In the mind of Veena Sahajwalla, the way we think about waste is rubbish. The award-winning scientist — who's also been dubbed Australia's "queen of waste" — wants to start a revolution in recycling.

For her, recycling doesn't need to replace like-for-like.

Instead, she wants us to imagine a future where all things can be unmade into their component parts, like turning old tyres into steel (something Professor Sahajwalla's pioneered).

In this talk from the Australian Museum, the inventor of green steel tells us why we're on the cusp of a recycling revolution.
