Ace Ethanol, Wisconsin's first large-scale corn ethanol production facility, announced a partnership Friday with Sweetwater Energy of Rochester, N.Y., to generate cellulosic ethanol at Ace's plant in Stanley for up to 16 years.

The contract, which has a potential value of more than $100 million, calls for Sweetwater to convert locally available non-food biomass such as crop residues, energy crops and woody biomass into fermentable sugar, which Ace will ferment into ethanol.

"Ace Ethanol has been bench testing Sweetwater's cellulosic material for some time and we're confident that this project will be commercially profitable," said Neal Kemmet, president of Ace Ethanol. "With Sweetwater, we'll move from 100 percent corn to a combination of corn starch and 7 percent cellulosic sugar as our feedstocks."

The agreement calls for Sweetwater to place one of its cellulosic facilities adjacent to the Ace Ethanol site, and deliver enough refined sugar for Ace to produce up to 3.6 million gallons of ethanol per year during the initial phase of the relationship.

These companies are taking all the matter that should be put back into the ground and using it for other purposes. Someone will have to build a huge chemical plant somewhere to make fertilizer to put nutrients back into the ground.

Is this partnership a means to put off the inevitable bankruptcy in an industry that can't survive without subsidies?


This article means nothing. Who is ACE, WHERE are they located, WHO do they employ and how many jobs do they provide directly and indirectly, WHEN will creditors be paid, finally WHY should the readers care? Can you give us some background to make this article relevant?
