Transforming Waste into Green Concrete,
Clean Air, and Clean Water

We've brought together 300 of the brightest people on earth and created technology to turn waste into valuable resources like green concrete, clean drinking water, biochar and green hydrogen.


We're taking stuff that's normally considered garbage and turning it into things that are actually useful, profitable and can make our world a better place.   


We're also working hard to remove carbon from our atmosphere, clean up our oceans, and make sure things are better for future generations.

Brittany Zimmerman introduces herself, Yummet's mission,  technology, and plans for the first, full-scale production facility to be built in Hawai'i with the help of industry leaders and passionate supporters like you.

what we do

What we do

By mimicking the natural process of mother nature, Yummet's innovative technological approach breaks down waste and transforms it into valuable minerals, soils, water and clean air.  Greenhouse gasses are removed from the atmosphere and oceans, while solid waste, plastics, glass, metals, construction waste, sewage waste, and agricultural waste are diverted from landfills and waterways and used as inputs in the Yummet facility.


We disassemble the molecules and rebuild them\ into valuable resources just as nature does.   We commercialize our outputs into green, carbon negative concrete, clean Hydrogen fuel, potable drinking water, and a sustainable soil amendment called biochar.  The result is a solution that rebalances the carbon of our planet.

Building Blocks


We developed the world’s strongest carbon-negative concrete.

3-5x stonger than traditional concrete.

Rocket Launch


We produce Green Hydrogen at scales and costs that rival dirty hydrogen production.

Glasses of Water


The 1st system that produces drinking water through desalination and wastewater treatment without producing brine nor waste.

Black Soil


The USDA Program 808/336 has ~$40B and is now reimbursing agricultural application of our Biochar.
