Liquid biofuels—including ethanol, renewable diesel, and sustainable aviation fuel—are a key part of a low-carbon energy future.

Our mission is to revolutionize biofuel production with hyper-efficient, electrified, energy-recovery systems that dramatically reduce energy usage and carbon intensity while saving facilities money.

Our patented designs can retrofit existing facilities with minimal disruption to operations, and are already commercially proven in the field, including at Europe’s largest biorefinery (Pannonia Bio).

Commercial History

Versions of our technology, mechanical vapor recompression (MVR), have been widely deployed in single processes, but integrated, comprehensive designs that consider multiple processes are relatively revolutionary and novel.

EII has been awarded 10 patents for its technology in the United States (USPTO), with multiple additional patent filings spanning Canada, Europe, South Africa, China, Brazil, and India. The patents validate our innovative incorporation of proven process concepts into comprehensive, integrated designs that improve efficiency, save project capital, and mitigate risks.

Today, integrated MVR systems from EII are in operation at Pannonia Bio, with additional plants’ systems under development. The systems' demonstrated flexibility, reliability, and efficiency attest to the technology’s commercial value.

Process Engineer
Zach Schafer
Zach’s interest in chemical engineering started early in life due to his father’s career as an engineer in the natural gas industry. He studied chemical and biological engineering at Colorado State University, and received a Master of Science in materials science and engineering from Arizona State University. Zach joined EII in 2022 as a process engineer, undergoing an intense immersion into MVR process engineering guided by then-CTO Lynn Crawford. Since Lynn’s retirement, Zach has taken on process engineering responsibilities for EII.
Former CTO (retired)
Lynn Crawford
Lynn Crawford’s early life on his parents’ farm near Frederick, South Dakota, gave him an early appreciation for agriculture and the potential benefits of renewable energy. He studied physics and chemistry at South Dakota School of Mines and taught undergraduate Engineering Thermodynamics while in graduate study at Montana State University. The combination resulted in his recognition of the importance of a positive energy balance for biofuels. He designed a plant with an MVR system that began operations in 1982—far in advance of today's mature ethanol industry.
