A group of students of the Panchayat Union Middle School in Tamil Nadu have been using eco-friendly pens in an effort to check the usage of plastic materials.
A majority of the students use the use-and-throw plastic pens available in the market, which badly affect the environment.
Plantain leaf, papaya leaf stem, coconut leaf, and castor stem are used as body of the pen. They have fixed the nib at one end of the stem, and closed the other end using maida starch to hold the ink.
Noville Opticians, an England based independent optician has launched spectacle frames that are made of eco-friendly plastic.
The frames are made of plastic which has 65% castor oil content. The material called natural PX is light and flexible.
It is known that castor oil is being widely used in pharmaceuticals, cosmetics, soaps, lubricants and more.
US based Zeal Optics, developed its sun glass frames, using a bio-based plastic made from castor bean oil. Zeal Optics uses castor oil to produce Z-ResinTM, which makes up the foundation of their entire line of frames (as opposed to using crude oil, which is what sunglass frames are traditionally made from).
The company’s bio based lens,is said to be the first lens of its kind that provides an ecological alternative to crude oil based lenses. Currently ZEAL produces all their sunglass frames with Z‐resin, thus eliminating harmful crude oil from the manufacturing process.
