Eco-Friendly Ink

India has always been known for its use of vegetables, fruits, leaves, etc for producing dyes/paints. So it doesn't come as a surprise that two gujrati girls have used these materials to produce ink.

Two students of a school in Rajkot have developed an eco-friendly ink from vegetables and fruits which can replace the synthetic petrochemical-based ink used in sketch pens.

Following six-month long experiments to formulate the special ink, Pooja Dholakia and Ridhi Dasani of Rajkot's S. G. Dholakia school in Gujarat, were successful at deriving ink from fruits and vegetables. Both the girls are standard nine students.

During experiments, the ink was extensively tested for retention of originality of the colour on paper as well as cloth. Its shelf life was also ascertained.

"Vegetable dyes are also used in fabric printing. So we thought to use it in sketch pens as well. So we tried to analyze what happens from the colours extracted from vegetable and flowers. When we experimented, we got many colours, and hence, we initiated the project," said Pooja Dholakia

The duo has formulated six natural eco-friendly ink colours by crushing beetroots, turmeric and coriander and motley of other vegetables. The inks are suitable for sketch pens and markers.

The idea to extract ink from vegetables and fruits struck Pooja' mind after she noticed some young students at her school licking ink from sketch pens. She made up her to do something for the safety of all others. She consulted with her friend Ridhi and both of them experimented.

"Bright" minds indeed!
