The Indian state of Sikkim, the first 100% certified organic state in the world, has introduced re-usable bamboo water bottles for tourists to encourage them to stop littering.
The all-organic state previously made headlines when it became the first in India to completely ban the use of plastic water bottles, and other single-use plastics, over 20 years ago.
They have now gone one step further to strengthen their reputation as a committed eco-tourism destination, and ensure the beautiful Himalayan paradise is kept pristine.
Tourists are being asked to leave their plastic bottles at the border and to instead start using the reusable water bottles, available at most shops.
There are various re-usable options on offer at the shops including the bamboo ones made by a local Indian man.
These bottles cost between $3 and $5 and they are also biodegradable in case they are ever disposed of or lost.
The bottles have a cork attached to a bamboo cap to seal them and keep the contents securely inside when on the move.
During the annual Tibetan New Years’ festival last month, the town of Lachen purchased 1000 of these bottles to introduce them to the public.
