How can we repurpose waste into valuable assets? Former Aurecon Managing Director for design, innovation and eminence Kourosh Kayvani chats with materials engineer and inventor Veena Sahajwalla about revolutionising recycling to help industries repurpose waste as a low-cost alternative to raw materials and fossil fuels.

In this episode of Engineering Reimagined, Veena shares her breakthrough invention of recycling used rubber tires from cars into parts replacement in steel-making, inspiration in becoming an inventor and the role of art and design in scientific disciplines. We also explore the concept of micro-recycling, the future of e-waste and green micro-factories.

“The fact that waste materials are complex, but yet, they offer us this beautiful opportunity to manufacture products so that we can actually be so much more sustainable in the way we make our materials and our products, to me, it's absolutely fascinating and mind-blowing,” says Veena.
