Whitefox Announces its Fifth Successful ICETM Start-up in the U.S. at Ace Ethanol in Wisconsin

Whitefox’s Membrane Technology is now installed in a third of all Wisconsin Ethanol Plants

Stanley, Wisconsin, April 24, 2019 – Whitefox Technologies Limited is proud to
announce its fifth successful installation and start-up of its Whitefox ICETM
system at ACE Ethanol’s plant in Stanley, Wisconsin. One-third of all Wisconsin
ethanol plants now have a Whitefox ICETM system installed.

Whitefox’s membrane solution is a key part of a wider project that will integrate
with D3MAX’s technology for taking corn kernel fiber-to-ethanol, enabling
significant energy savings for the integrated facility.

Neal Kemmet, president and general manager at Ace Ethanol, LLC and Fox
River Valley Ethanol LLC said, “After seeing the benefits of the Whitefox ICE™
membrane system at Fox River Valley Ethanol in Oshkosh, we were eager to
replicate the energy reduction solution at ACE. Whitefox has demonstrated its
ability to help our two plants reduce energy consumption and reduce loadings on
our columns and mole sieves. We are also running a more stable production at
the plant, which is an additional benefit we didn’t anticipate but is greatly
appreciated by our folks in the control room. We are experiencing a positive
impact on our energy consumption plus a reduction in our carbon emissions and
cooling.”

Gillian Harrison, CEO of Whitefox said, “Working with Neal Kemmet and his team
at both ACE Ethanol and Fox River Valley Ethanol has been really rewarding for
us at Whitefox. We are excited to be part of a project bringing D3MAX’s
technology to the industry. Energy and water efficiency are central to Whitefox’s
purpose and we were pleased to see USDA’s recent report that projects that by
2022, with further improvement, US corn-based biofuels could reduce
greenhouse gas emissions by 70% compared to gasoline. ACE is showing
leadership by investing in new technologies to further improve the sustainability
of US biofuels and we are proud to be part of such projects.”

Wisconsin is home to nine ethanol plants and is the ninth largest ethanol
producing state in the country. It has the capability to produce 500 million
gallons of ethanol per year.
