Indian Institute of Technology – spins off a start-up, EnNatura, working on green ink

BY 2017 printing presses around the world will lap up 3.7m tonnes of ink, worth some $18 billion. Most of it will contain hydrocarbon-based solvents resulting in emission of volatile organic compounds (VOCs), an undesirable by-product of the manufacturing process 다운로드. But not all. EnNatura, a company spun out of the Indian Institute of Technology in Delhi has created a formula for making ink that is environmentally friendly 맥용 kies.

In the creation of ink, the current “mixture is spiked with petroleum distillates…EnNatura’s proprietary resin chemistry does the same thing using castor oil, a natural purgative.”

Other companies, especially in America, make biodegradable ink 다운로드. But most use petrochemicals to clean the resin from printing plates once the printing job is complete, which defeats the purpose. EnNatura, by contrast, employs a liquid concentrate made from a surfactant, a substance which, when mixed with water, eats into the resin and scrapes it off the printer 다운로드.
