Veena Sahajwalla, material engineer

What if we saw rubbish as a valuable resource? Scientia Professor Veena Sahajwalla is an inventor, engineer and leading expert in the field of recycling science. She is the founding Director of the Centre for Sustainable Materials Research & Technology (SMART) at the University of NSW. Making waste valuable, her first invention reduced carbon emissions from the steel industry, and her second is promising to empower communities to become their own manufacturers. Adding a few more ‘r’s to the reduce, reuse, recycle list – such as reform and remanufacture – she is upending existing systems to engineer solutions for a waste-free world. Comedian Bec Charlwood is excited to be on such a classy podcast and we're thrilled to have her help host Rachel Rayner unravel our trash to reveal the treasure within.

Patti Talks Too Much Patti Hi. I'm Patti and it's been said - many times - that I talk too much. I'm a teacher, author, nature lover and for ten years I owned a coffeehouse cafe where my faith in the goodness of humans was restored every day. This podcast highlights the awesomeness of humanity - er...outside the warmongers, globalists, tyrants and politicians in general. You know, the rest of us weird, quirky and sometimes hilarious humans. We'll talk woo, probe mysteries and leave you thinking about something more interesting or entertaining or uplifting than your grocery list, or boss or that oil change your car needs. I talk too much because I can't help my Gemini moon and Leo Rising nature. I do a podcast because it's cheaper, funnier and more productive than therapy.
