Utilizing Carbon in Everyday Products w/ Aaron Fitzgerald of Mars Materials
Welcome back to another episode of the CleanTechies Podcast. This is episode 74 of the show and we are thrilled to have you joining us. If you're a ClimateTech Founder seeking introductions to capital or potential partnerships or are interested in sponsoring the show, please reach out: silasmahner@gmail.comToday we are joined by Aaron Fitzgerald the CEO and Co-Founder of Mars Materials. At Mars Materials they are creating a clean acrylonitrile (ACN) alternative that is used in materials that every person on the planet (nearly all) uses every year. Uses include carpet, carbon fiber products, waste treatment, and keyboards among other things. Conventionally, acrylonitrile is made from fossil fuels and their tech replaces the feedstock with other materials making it a much cleaner material. Their tech came out of NREL and is a way of sequestering carbon into these everyday materials helping reduce their carbon impacts of them. In addition to this being a conversation about incredible technology, Aaron's story is also very compelling so I'm glad to be able to share this discussion for that as well. Hopefully, it will inspire many. Without any further delay, please enjoy this conversation with Aaron Fitzgerald.

This was our first time talking about this topic, and for me, it was the first time I really have ever heard the argument for Propane.
