Soy ink benefits
Soy ink and the environmentSoy ink may be the solution to the environmental health and safety concerns of the printing industry. A new study confirms that soy ink can help to reduce the environmental burden of the printing industry. Soybean oil comes from a renewable source: soybeans. Soybeans beans are widely available at low cost. Soybean agriculture uses only 0.5 percent of the total energy needed to produce soy ink. Almost half of all soybeans produced in America needs no irrigation. As soybeans are growing they temporarily remove damaging carbon dioxide, a greenhouse gas, from the atmosphere.
Soy ink is naturally low in VOCs (volatile organic compounds, chemical compounds that evaporate and react to sunlight) and its usage can reduce emissions causing air pollution.
Researchers at Western Michigan University have found that soy ink is removed more effectively from newsprint than petroleum ink during de-inking, resulting in less paper fiber damage and a brighter paper. In addition, the waste is not considered hazardous and can be treated more easily, completely and cost-effectively. Residue waste ink is considered a liquid industrial waste that requires proper disposal. Many newspapers and large commercial printers are recycling their ink by mixing black ink with unused color inks. This process reduces waste and results in a more cost-effective, efficient use of ink.
Other benefits of soy inkSoy ink is available for newspapers, magazines, commercial printing, packaging, business forms and many other uses. Each form of printing requires a different type of ink and manufacturers have made various efforts to meet with the demands of customers. Soy inkt has following benefits:
