With mountains of non-biodegradable pens piling up in their bags, school students Dhanraj, Danush, Manojkumar, Jothipriya, Sankar, and Tamilselvan were keen on finding a sustainable alternative. What these students of Panchayat Union Middle School in Pudupalayam Village, Tamil Nadu, then created was an organic pen which, when disposed of, converts into organic manure.
The pen is made from plantain leaf, papaya leaf stem, coconut leaf, and castor stem, and the tube is sealed with maida starch at one end and filled with ink. The only thing about the pen that is not organic is its nib. These pens, which can be used for a few months before being discarded, have been in use at the school for some time now.
This invention has already been reviewed by the Tamil Nadu Science Forum and will soon be submitted at the prestigious National Science Congress 2017, says a report by Homegrown.
According to a report by The Hindu, S Dinesh, a teacher who has mentored these children, said,
The project was designed for the National Science Congress 2017. The Thulir Illam unit sponsored by the Tamil Nadu Science Forum functioning in the middle school has been submitting different projects in the National Science Congress for the last few years.
Over the last few years, there have been a number of inventions that will help reduce the harm we cause to the environment. A couple from Bengaluru developed handmade cigarette filter tips that when disposed of, release live seeds into the ground. A California-based company called Reduce. Reuse. Grow has designed a coffee cup which is not just biodegradable but also has seeds that can be planted and grown embedded in its walls.
