Butamax and Highwater Ethanol Break Ground on Biobutanol Retrofit Project
Including Installation of Novel Corn Oil Separation Technology

WILMINGTON, Del., Oct. 2, 2013 (GLOBE NEWSWIRE) -- Butamax™ Advanced Biofuels
LLC, the leading biobutanol technology company, and Highwater Ethanol LLC, a
leading producer of first generation ethanol, have begun to retrofit
Highwater's ethanol plant in Lamberton, Minnesota for the production of
biobutanol. Butamax's cutting edge technology package will include the
installation of novel corn oil separation technology. Butamax and Highwater
have entered into definitive agreements for license of Butamax's patented corn
oil separation technology, which is an integral part of a full retrofit to
biobutanol production and can also be installed independently as a first phase
of the conversion.
Installation of the patent protected Butamax separation system has already
commenced with commercial production expected this winter.

Butamax CEO Paul Beckwith said "This is an important milestone for Butamax and
its partners. We formulated a strategy to provide the most advanced technology
to improve current biofuel production, offer better co-product profiles, and
pave the way for near-term, large-scale isobutanol production. Today, our
vision is becoming reality."

Highwater Ethanol CEO, Brian Kletscher stated, "We investigated other options
for corn oil recovery, but we had the advantage of seeing the Butamax system
first-hand and we were impressed with what we saw. Not only was the production
class leading, but the expertise Butamax assembled is unparalleled, including
experts from BP, DuPont and Fagen. We are very excited to execute this stage
and move to negotiations for biobutanol production."


Beckwith added, "We have spent significant time and energy building the right
team and developing and protecting the right technology. We could not be more
excited about the next steps towards a whole new biofuels industry."

Additionally, Butamax has reached agreement with Fagen Inc. for the
engineering, procurement, and construction (EPC) of this project and as part
of Butamax's vision for roll-out of its full biobutanol production technology.
