In this unique episode we are joined by Kidus Asfaw, Founderand CEO of Kubik - an Africa-based start-up transforming plastic waste into low-carbon construction materials that are cheaper and faster to build with than cement. Joining Kidus is our youngest guest to date, Helen Tekalign. A prodigious young student and already the winner of many local STEMcompetitions, Helen is in 8th grade at Pharo School Assosa located in a rural area of the BGRS state on the western edge of Ethiopia. The two discuss their entry into the field of STEM, and Kidus shares his journey from young tinkerer to CEO of his own successful start-up, and how he hopes to see Helen and other Ethiopian students like her do the same.
