Bigger Than Us

By Nexus PMG

Nexus PMG welcomes you to the Bigger Than Us™ podcast, which we, as energy geeks lovingly refer to as the BTU. Bigger Than Us is a podcast that focuses on ideas that will shape the future of our planet and ultimately, our existence. We will occasionally lean into energy topics because after all, it’s the key to our collective survival, but we’ll also explore other areas that we believe will have an effect that is Bigger Than Us.

#218 Brittany Zimmerman, CEO of Yummet

Brittany Zimmerman, Founder and Chief Executive Officer of Yummet. Brittany is the CEO of a globally recognized organization with a diverse team of over 300 graduate-level experts hailing from over 50 countries. This organization has bridged the gap between space technology and terrestrial applications by bringing advanced solutions to meet the needs of humanity on earth. By mimicking the natural process of mother nature, Yummet's innovative, proven, and patent-pending technological approach breaks down waste, disassembles the molecules, and rebuilds them into valuable resources, minerals, soils, water, and clean air - just as nature does. In doing this they produce the strongest, most net-negative concrete ever tested made entirely from waste. They produce biochar that serves as a sustainable alternative to synthetic fertilizers, restoring soil health and purifying water. They desalinate water and treat waste water with no production of brine or other waste products. They produce Green hydrogen at costs that rival dirty hydrogen, providing an alternative to fossil fuels.

Ms. Zimmerman was selected early in her career as the Youngest National Aeronautics and Space Administration (NASA) Principal Investigator. She served as Principal Investigator (PI) for three NASA Programs.

She served as Program Manager and Lead Engineer for the NASA Integrated water Recovery Assembly (IRA) designed to reclaim water from planetary surface habitats for NASA. As Lead Systems Engineer for the Brine Processor Assembly (BPA), currently on the International Space Station, Ms. Zimmerman spent years designing, analyzing, testing, and managing programs that utilize membrane distillation for water recovery during on-orbit and planetary surface operations. This includes her role as Program Manager and Lead Engineer for the Boeing Starliner Humidity Control System (HCS) ammonia testing campaign, and her role as a PI, Lead Engineer, and Inventor of the NASA Condensate Separator for Microgravity Conditions (COSMIC).

Ms. Zimmerman’s role as Lead Engineering Analyst for the United States Special Operations Command (SOCOM) RAIDER program showcased her strength at mathematical analysis of thermal and fluid solutions. She has supported the development of the environmental control and life support systems (ECLSS) for a single person spacecraft and has been instrumental in the design of many extreme environment United States Department of Defense (DoD) ECLSS solutions.

Ms. Zimmerman earned her B.S. of Mechanical Engineering in 2011, followed by an M.S. in Space Studies focused on bioregenerative physical-chemical hybrid life support systems for long-duration spaceflight. Ms. Zimmerman specialized in the ecology of closed environments and biospherics, for which she designed the greenhouse module for the NASA Inflatable Lunar/Martian Habitat (ILMH).

Ms. Zimmerman has been a crew member on several analog Mars missions, including a mission to the Mars Desert Research Station, as an officer of Mission 171. She served in the ILMH, leading Crew 3, the first all-female crew.

Her background also includes rocket design, robotic launch systems, and high-altitude ballooning.

Mark Toman is the Founder & President of EggTech, as well as a forward-thinking and mission-driven entrepreneur.

Prior to founding EggTech, Mark held several strategic business development roles, focused in the areas of corporate strategy, innovation and partnership cultivation.

After being involved in the mining industry, Mark identified the possibility of utilizing a vast wastestream from liquid-egg processing operations, which would otherwise predominantly go to landfill, in the interest of offsetting the need to mine for raw material, and in hopes of being in a position to manufacture a pure form of calcium (as well as other nutritionally advantageous ingredients) for supply into the premium nutritional/ingestible markets.

Mark and his team were successful in developing an industrially-scalable and cost-effective process that has been formally patented in the US, Canada, Mexico, the EU, China, and India.
