You enjoyed the fizz but don't know what to do with the polyethylene terephthalate (PET) bottle. Don't worry, students of a Jamshedpur cradle, Tarapore School in Agrico, have a bright green idea.

Over 200 students of the school, from Classes VIII to IX, have recently learnt how to grow a garden using the PET bottle as the container for saplings.

Now, students will try to reuse these beverage bottles by developing gardens growing entirely in them - a natural showpiece that uses very little space and hence is ideal for space-crunched cities - instead of buying earthen tubs and pots.

People for Change, a city-based NGO, trained the students on June 18 and 19 on how to make this bottle garden possible as an eco-friendly project titled Garbage to Goal.

Hashneet Kaur, a Class VIII student who is taking part in the project, feels a tower garden is a great idea.

"At every home, you have these old PET bottles that keep piling up. We've learnt a unique way to use them to add a touch of green to our planet," this eighth grader said.

She elaborated on what they learnt.

"Saplings of decorative plants can be grown in used PET bottles. We set the bottle horizontally and scoop out the middle portion of a bottle, put soil in it and plant the sapling. And, with the help of wires, you can have a vertical chain of such PET planters. That's the tower garden concept," Hashneet said.

"It will look amazing on balconies at home too," she added.

Tina Bodhanwala, administrator, Tarapore School, Agrico, said they wanted to do something fresh and inventive. "Students must also know how to reduce and recycle waste. We will come up with a garden in the school premises where we would use these planters. Walls can also look pretty with these planters," Bodhanwala said.

PET planters apart, Tarapore students planned a kitchen garden where they would grow chillies and tomatoes as of now. They also learnt to make brooms and paper bags with beautiful collage on them.
