NGO Samajbandh works with middle-class, lower-middle-class and Adivasi or tribal women on menstrual health and education. They use old and discarded clothes to make cloth pads called 'Asha Pads'. Once collected in Samajabandh's Pune office, the clothes are sorted by fabric into hosiery, denim, cotton and synthetic clothes. While cotton and hosiery help keep the pad soft and absorbent, denim comes on as the last layer to help keep the Asha pad leakproof.
