Once you have collected a minimum of 30 bottles, you can send them to us and we will hand them over to our partner-Chintan, a sustainability organisation committed to recycling and upcycling. Please ensure that the bottles and caps have been rinsed. On a paper write: your name, order number, email address and your feedback too. Courier the bottles, caps and the note to "Recycling Team, GoodVitamin Foods Pvt. Ltd. House Number: 27/9 C/O DTDC 3PL Fulfilment Limited, Internal Road, Kapasehra, South West Delhi, 110037 Ph: 7838437657" That's it! You have done your bit to save the environment. As a reward, we will email you a special 25% discount coupon for your next purchase once we receive the package.
