Far from taking corn out of the global food supply the distillation process yields a protein-rich grain byproduct that's being used to feed livestock.

The deficit I am talking is the US imports too much and exports too less.

Thus exporting lots of corn is good.

The US is transforming itself on a ag export juggernaut. Exporting corn to pay for Chinese high tech goods.

The rise in corn exports continues despite the fact that maize is proving to be a viable alternative energy source for crude oil, a commodity on which the U.S. economy has become over-dependent.

The analysis below lists the countries that imported the most corn from the U.S. in 2007.

and wiht higher prices ethanol is coming back com gusto:

Plants mothballed during the economic downturn are reopening. Domestic ethanol production hit record levels last year, topping 13.2 billion gallons, according to the Renewable Fuels Assn. in Washington. Oil companies including Valero Energy Corp., Sunoco Inc. and Marathon Oil Corp. that snapped up facilities when the industry hit a rough patch a few years ago are looking to expand.

One tonne of corn produces 378 L of ethanol and 479 kg WDG (70% moisture content), or 309 kg of DDGS (10% moisture content).

Wet and Dry Distillers Grains

There are two common types of distillers grains.

Wet Distillers Grains (WDG) contains primarily unfermented grain residues (protein, fibre, fat and up to 70 per cent moisture. WDG has a shelf life of four to five days and involves the transport of 70 per cent water by weight of total product. WDG supply transport is economically viable usually within a 200 km radius from the ethanol production facility. These facts are important as they affect both profitability and logistic issues.

Dried Distillers Grains with Solubles (DDGS) is WDG that has been dried with the concentrated thin stillage to 10-12 per cent moisture (Figure 1). DDGS have an almost indefinite shelf life and may be sold and shipped to any market regardless of its vicinity to an ethanol plant. Drying is costly, as it requires the input of further energy. In the US, it is packaged and traded as a commodity product
The nutrient composition of distillers grains, depends on the type, variety and quality of Dry mill ethanol processing creates wet and dry forms of distillers grains.
