Where is corn ethanol produced?

U.S. ethanol plants are concentrated in the Midwest because of the proximity to corn production. Plants outside the Midwest typically receive corn by rail or use other feedstocks and are located near large population centers.

What plant produces the most ethanol?

Corn
Corn is the leading U.S. crop and serves as the feedstock for most domestic ethanol production. Corn ethanol meets the renewable fuel category of the Renewable Fuel Standard (RFS), which is limited to 15 billion gallons.

Which plants are used for industrial production of ethanol?

Ethanol Crops

• Sugary Crops- Sugarcane, sugar beet, rotten fruits and molasses.
• Starchy Crops- sorghum, grain sorghum, switch grass, poplar, barley, hemp,
• potatoes, sweet potatoes, cassava, sunflower, stover, grain, wheat.
• Cellulosic Crops- wood, paper, straw and cotton.

How much ethanol can be produced from a bushel of corn?

Modern dry-grind ethanol plants can convert corn grain into ethanol (2.7-2.8 gallons per bushel) and DDGS (17 pounds per bushel). This rather energy- efficient process produces a renewable liquid fuel that has significant impacts on the agricultural economy and energy use in the U.S.

How much ethanol can be produced from corn stover?

Production of second-generation biofuels is now under way, with three major facilities on track to produce a combined 80 million gallons per year of ethanol from corn stover. Stover is the corn plant residues typically left in the field after corn grain harvest—the cobs, husks, leaves, and stalks.

Where is corn stover going to be produced?

A new DuPont facility in Nevada, Iowa, is expected to generate 30 million gallons annually of cellulosic biofuel produced from corn stover residues. It opened in 2015, with full production provisionally delayed until 2017.

What do you use to make corn stover?

Stover is the corn plant residues typically left in the field after corn grain harvest—the cobs, husks, leaves, and stalks. Stover has the advantage of not being a food source like corn itself, and as a by-product of corn production, it has lower production costs.

What kind of enzymes can corn stover be used for?

In addition, corn stover is considered as a promising substrate for the production of industrially important enzymes (e.g., cellulases and xylanases) that are widely used in animal feed, food, textile, brewery, wine, laundry, as well as pulp and paper industries.
