    • Proven to continuously run and scale on wide variety of feedstocks



The Pennsaco technology has been thoroughly tested and its continuous operations, ability to process a wide variety of feedstocks, economical design, low emissions, and high energy conversion rates confirmed by the United States Environmental Protection Agency, ensuring its practical application in a wide range of plant environments. Our core process is tried and true, and its efficiency is well-documented through more than a dozen existing & new patents.


One system, two carbon negative green hydrogen  pathways.  Pennsaco has pioneered production of carbon negative green hydrogen from waste through one system with two patented pathways that produce high volumes of low cost, carbon negative, pressurized hydrogen at rates 30% greater than current state of the art while simultaneously permanently removing tonnes of carbon from the atmosphere.  We make 4X the yield of green H2 of wind or solar at 8-10X less cost and 2-4X the yield of green hydrogen of thermal conversion technologies from the same amount of feedstock.


Pennsaco’s management has decades of proven experience developing and commercializing breakthrough clean energy & recycling technologies, financing & developing projects, designing, building, and operating commercial plants for waste management and renewable energy, leading industry advocacy & government relations, and breaking new ground in R&D.


Pennsaco’s technology is feedstock and product flexible, scalable, customizable to local needs, and serves multiple global markets worth trillions of dollars.


Pennsaco Technologies can be deployed anywhere in the world, advancing 12 of the 17 United Nations Sustainable Development Goals with each facility and generating billions of dollars of wealth creation

Dr. Mack Bowen, PhD, Chief Technology Officer Emeritus

Dr. Mack Bowen is Chief Technology Officer of Pennsaco. Dr. Bowen has over 30 years experience in thermal science and biomass conversion technologies and is the holder of patents covering more than a dozen claims in biomass conversion, hydrogen production, and gas to liquids. He is the lead inventor and developer of Pennsaco’s core technology, and he is responsible for the advancement of the company’s technology road map. Dr. Bowen manages all relationships with research facilities and commercial engineering firms.

Dr. Bowen developed the technology while a professor at the Georgia Institute of Technology (Georgia Tech), one of the country’s leading bioengineering and bioscience research universities. A multinational packaging manufacturer licensed the technology to capture and retain resources from waste streams, divert trash from landfills, and reduce material costs in their packaging facilities. It was commercialized under Dr. Bowen’s direction, and four successful industrial plants were built and operated prior to the company’s transition from manufacturing to financial services, and its subsequent divestment of Dr. Bowen’s division.

Dr. Bowen previously worked on defense and aerospace for Lockheed and Martin (now one company) developing high-heat transfer materials necessary for rockets to withstand intense thermal pressure generated in hypersonic velocities.
