The use of soy ink has greatly decreased solvent disposal problems for the printer.
Soy ink does not release a significant volume of volatile organic compounds (VOCs) into the air when it dries. VOCs are chemical compounds that evaporate and react in sunlight and form smog at lower atmospheric levels.
Soy ink is not 100% biodegradable, but it is far more biodegradable than oil solvent-based inks. Furthermore, soy ink is more effectively removed from papers during recycling, resulting in less paper[paper?:paper sample maker cutting machine] damage and a brighter paper. The use of soy ink helps printers meet the federal Environmental Protection Agency's clean-air standards. Waste papers are generally recycled by the printer as well.
