The CES OxyNol™ Process
The Core of Masada


Masada and its affiliates developed the proprietary CES OxyNol™ Process to safely process and dispose of garbage and sewage sludge while generating ethanol, a renewable clean-burning fuel.

To the best of the company’s knowledge, the CES OxyNol Process is the only fully developed and demonstrated commercial process that produces ethanol from municipal wastes.

The CES OxyNol Process was the result of a public-private research partnership among Masada, the NREL, the TVA and Mississippi State University.

Though based upon a core process that was widely utilized in World War II, the current CES OxyNol Process represents the successful culmination of years of research, development and demonstration for commercial deployment.

Masada tested the CES OxyNol Process and major vendor equipment extensively at the TVA’s biomass-to-ethanol conversion facility in Muscle Shoals, Alabama. In Masada’s process development phase, cellulose separated from MSW was successfully converted to sugar via acid hydrolysis. The sugar was then fermented and distilled to produce ethanol. Masada added key economic technologies to make the entire process commercially viable.

In 2002, working in collaboration with Evolution Markets, Inc. (, Masada assessed the commercial and technical viability of using the CES OxyNol Process as a basis for creating Certified Emission Reductions (“CERs”) under the UNFCCC. Masada completed the detailed analytical work necessary to determine whether the CES OxyNol Process reduced the carbon footprint typically associated with landfilling operations and quantified the carbon emission reductions. A typical Masada plant, processing a minimum of 1,000 tons of MSW per day, produces 280,342 tons of CO2 equivalent emission reductions per year.

To date, over $55 million USD has been invested in the development and deployment of the CES OxyNol Process.


Masada’s core CES OxyNol waste-to-ethanol process was proven at industrial scale during WWII. Four years of testing with the TVA demonstrated the process’s viability and flexibility. Twenty-first century updates use off-the-shelf equipment to minimize risk. Key process systems and hardware are in daily operation in similar applications and have been thoroughly tested at a large-scale demonstration plant.

The CES OxyNol process involves five steps whereby the cellulose in municipal wastes is converted into sugar (primarily glucose). The sugar is subsequently fermented into alcohol, which is denatured to produce fuel-grade ethanol.

The process is illustrated below:
