NEWS FLASH!!! - Ethanol plants produce a co-product. It is called animal feed DDGS (Distillers Dried Grains) You take feed corn to the ethanol plants & you get back both food & fuel!!!
Cattle that would have eaten the corn grain and soybean meal to supplement their diet, now eat distillers grains as that part of their balanced diet. Equal or better performance (rates of gain for beef cattle or milk yield in dairy cows) are usually reported when diets with up to 20% of their food intake from distillers grains are compared with control diets.
NEWS FLASH! Government invents perpetual motion machine!
The corn starch caused methane in cattle that was released into the atmosphere. It was not making beef, hamburgers, steaks or milk. Methane gas is 15 times more powerful of a greenhouse gas than CO2. Now this starch is converted into ethanol instead of methane gas.
