Eemsborg loading beet pulp Terminal A Duluth Minnesota

Beet pulp from Duluth, Minnesota, is primarily a byproduct of sugar beet processing in the Upper Midwest, handled and exported through the Duluth-Superior Harbor via facilities like Hansen-Mueller's Grain Elevator A. It is dried, pelletized, or shredded for storage and transport, and its main applications focus on animal nutrition due to its high digestibility, fiber content, and energy value as a low-starch carbohydrate source. Here's a breakdown:
1. Animal Feed (Core Use)
Livestock (Cattle and Dairy): Widely used as a structural carbohydrate in dairy rations to lower rumen acidosis risk, improve butterfat production, and extend forage supplies. It's a non-starch energy source for beef cattle, stock cows, and lambs, often supplementing corn or soy.
Horses: Popular for its palatability and low sugar; soaked in water to aid hydration, prevent colic/ulcers, and support older horses with chewing issues. It enhances coat bloom in show animals and replaces part of hay rations.
Other Animals: Fed to goats, sheep, and pigs for fiber and energy; firms stools for cleaner operations.
Pet Food Ingredient: Acts as a lower-tract cleanser and stool firmer in dog/cat foods.
2. Export for International Feed Programs
A significant portion is shipped from Duluth to Europe (e.g., Netherlands) and Japan as pelleted dried beet pulp for animal feeding programs, aiding global trade balance.
3. Emerging Biotechnological Applications
Beyond feed, it's explored as a feedstock for biofuels, biohydrogen, biodegradable plastics, and chemicals like lactic/citric acid, though these are not yet primary in Duluth-sourced pulp.
