Smart phones, computers, televisions and even children's toys are part of what makes our modern world so exciting. But these often rely on plastics and rare earth metals which are hard to recycle. Are there efficient ways to capture all those rare earth metals? How are rare earth metals in old phones recycled today, and can we make it better? Knowing which bin to put plastic in is difficult, so what if there was a more universal way to recycle plastics? How does turning plastic into a gas with the help of steam help create a circular plastic economy? How can some steam power help crack plastics back into their most basic forms? Is it possible to recycle plastics without to build whole new plastic refineries? Regulation is often playing catch up to making materials safe. Are the latest generation of 'safe' fire retardants any safer than those that came before?
