About Us

GreenThinker DC was founded in 2019 to promote zero/low waste living in DC through education and support. Too much of our daily life revolves around disposable products and throwing stuff away. In reality there is no ‘away’ and our ever-growing pollution problem is harming both people and the planet. We strive to encourage individuals and organizations to learn more about and practice environmentally-friendly habits. GreenThinker DC hosts a weekly support group for those trying to reduce their waste and carbon footprint. We also have a directory of online and local zero/low waste resources, as well as a party supply library to borrow reusable dishes. We hope you will join us on this journey to promote sustainable alternatives to the wasteful status quo.

Board of Directors

Rini Saha, President and Founder

Rini Saha is the founder of GreenThinker DC. Its focus is to promote zero and low waste living in the DC area by teaching individuals and organizations to live more green. Rini spent most her professional career in secondary education. She spent 7 years as a special education teacher in various DC Schools. Rini’s passion for the environment came to her when she started to research recycling to teach her students. In her research she read some eye opening books, like Garbology, and Plastic- A Toxic Love Story. This started a slow journey to that led to a burning passion and a new calling. Rini is happy to join a movement of people who are trying to reduce their trash. Rini hopes GreenThinker DC will serve as resource for other like-minded people.
