Slide Soy Uses

After Harvest

After harvest, soybeans are either stored in a grain bin or sold to a processing plant, like Cargill in North Carolina. These processors are able to separate the soybean meal from the oil. When processed, a 60-pound bushel will yield about 11 pounds of crude soybean oil and 47 pounds of soybean meal.

Because soy is rich in quality protein and digestible energy, most of the soymeal is turned into animal feed, by baking the protein-rich fiber that remains after the oil is removed. The remainder of soymeal is used to make some soyfoods like tofu and soy milk. The soybean oil that remains after processing out the meal has many uses including cooking oil, biodiesel and bioheat, and non-toxic industrial supplies like paints and cleaners.

Animal Feed Production

The high-protein fiber that remains after soybean oil is removed is toasted and prepared into animal feed for poultry, pork, cattle, fish, and pets. Over half of the soybeans processed for livestock feed are fed to poultry. In N.C., however, hog farms are more abundant than poultry farms, making pigs the number one customer of N.C. soy.

Soy protein is increasingly found in fish food, both for home aquariums and for farm-raised aqua protein. Most marine species were fed fish meal at one time, but wild caught fish feed has become scarcer, making soyfeed a more sustainable and affordable choice.

Other Uses


Biodiesel fuel for biodiesel engines can be produced from soybeans through a process called transesterification. This process simply removes the glycerin from the oil. Soy biodiesel is desirable because it burns cleaner than petroleum-based diesel. Advantages include reduction of particle emissions, non-toxicity, renewability, and environmentally-friendliness.

Soy Crayons

Soy crayons made by the Dixon Ticonderoga Company replace the petroleum found in regular crayons with soy oil making them non-toxic and safer for children.


Biocomposites are building materials made from recycled newspaper and soybeans. They replace other products traditionally made from wood such as furniture, countertops, and flooring.


Soy products are used in many home and commercial carpets, as well as automobile interior upholstery.


Candles made with soybean oil burn longer, but with less smoke and soot.


Soy oil produces environmentally friendly solvent that safely and rapidly removes oil from streams, creeks, and shorelines without harming people, animals or the environment.

Soy Ink

Soy ink is superior to petroleum ink because it is non-toxic and easy to clean up.

Soy Tires

Goodyear has recently launched a line of tires made from soybean oil that rival traditional tires for performance, and are more environmentally friendly than petroleum-based tires.

Soy Foams

Soy-based foams can be used in refrigerators, coolers, automotive interiors, and footwear.

Concrete Protector

Brands like Poreshield have created non-toxic concrete sealants made from soybean oil that extend the life of paved surfaces.
