Why is soybean ink good for the environment?
Much of the soybean crop requires no irrigation, limited fixed nutrients, and leaves fewer agricultural residues than other crops. Soy ink also has low levels of VOCs, (volatile organic compounds) which helps to reduce air pollution by minimizing toxic emissions.
Why does soy ink take so long to dry?
A major problem with soy ink is that it takes more time to dry than petroleum-based inks, due to its lack of evaporative solvents in the form of VOCs. This creates challenges for some printing presses, especially those that use coated papers (such as magazines) instead of porous, uncoated paper (such as newspapers) where the ink can dry via absorption or IR in-line heaters. Current studies into UV -reactive ink curing are being conducted by many ink producers, most prominently the Flint Group. This process dries much faster, is cheaper, uses less energy, and emits no VOCs. This requires a significant equipment change and has not been scaled down to consumer size as of 2006.
When was the National Soy Ink Information Center established?
The National Soy Ink Information Center was established in 1993 by the Iowa Soybean Association to promote research and use of soy ink. The center created the SoySeal mark used to identify products meeting basic requirements. The success of soy ink was judged to be sufficient to justify the closing of the National Soy Ink Information Center in 2005.
Why use clearer soy bean oil?
By using clearer soy bean oil grades, less pigment is necessary to produce the same optical effect, which reduces the overall cost of the ink. Recent studies involving engineering of certain oils in the bean have resulted in even clearer oils.
Is soy ink biodegradable?
To make soy ink, soybean oil is slightly refined and then blended with pigment, resins, and waxes. Even though soybean oil is an edible vegetable oil, soy ink is not edible nor 100% biodegradable because the pigments and other additives that are mixed with the oil are the same as those used in petroleum-based inks.
Why is soy ink so popular?

Is soy a renewable resource?
Soy may be a renewable resource . But it does take diesel to grow soy, so thinking that each drop of soy ink used is a drop of petroleum saved is a fallacy. (For comparison, one reliable estimate for biodiesel production is about 2.5 gallons of soy biodiesel per gallon input of standard diesel fuel.)
What is soy ink?
Soy ink is made up of a slightly refined soybean oil incorporated with pigments, resins, and various waxes. These waxes and resins are usually natural based additives. Newspaper printing companies use soy ink regularly because of how easily the ink absorbs into the paper. As of lately, nearly ninety percent of American newspaper companies utilize soy ink as their ink of choice. A quarter of all commercial printing companies within the U.S. already use soy ink for their prints. Since refined soybean oil is clearer, this allows for less pigment to be incorporated within the oil for the color to show. Additionally, the clearer base allows for the colored ink to appear sharper and brighter which is more desirable when printing.

Is soy ink biodegradable?
The soybean oil within the soy ink is completely biodegradable; depending on what the additives of the ink are, they too can be 100 percent biodegradable. Soy ink produces no hazardous waste and makes the paper it is printed on much easier to recycle. During the de-inking process while recycling paper, soy ink can be removed more easily compared to petroleum-based inks. Unlike the petroleum used within inks, which is usually crude oil, soybean oil is completely renewable. Soybean oil is also low in VOCs, twenty percent lower than petroleum-based inks. This allows soy ink to comply with the Clean Air Act’s thirty percent limit on VOCs.
Is soy ink toxic?
Another downside can be the soy ink not being fully natural and non-toxic. Because the refined soy oil is only a component in the ink, depending on the manufacturer, the pigments added to the soy oil may cause it to become slightly toxic or unable to biodegrade fully. This downside can be resolved by picking a soy ink with safer pigments and additives.

Because factory availability is limited and they typically take a bit more time to work with, alternative inks can cost significantly more than traditional inks. But since ink is such a small fraction of the overall volume of your packaging, the cost increase per item is relatively small. Of course, to cut down on ink costs, you can design your packaging to use less of it.
What are pigments in ink?
Pigments are the concentrated powders that give ink its color. They can be derived from minerals or made synthetically. Before the mid-70s, many of the vibrant pigments in inks were made using relatively high levels of heavy metals like cadmium, arsenic, mercury, antimony, lead, and selenium.

Is paper biodegradable?
Newspaper is a biodegradable substance. The Nuffield Foundation, which focuses on science and social science, conducted an experiment with its students which demonstrated how microbes in the soil break down materials. In short, soil microbes contain enzymes that break down cellulose. Since paper is made from wood, and therefore is composed greatly of cellulose, soil microbes easily break down and digest paper. During this process, carbon is released into the soil. Carbon is an essential element to healthy soil. You can read more about the experiment, and how microbes digest these materials here: https://www.nuffieldfoundation.org/practical-biology/microbes-ate-my-homework
