India’s menstrual waste is estimated to be 1,13,000 tonnes annually. Around 121 million women and girls in India use disposable sanitary napkins. On average, an Indian woman bleeds 80 ml in one period cycle. A normal commercial pad can hold 5 ml to 7 ml of blood which means that women use at least 10 pads in one cycle. Sustainable menstruation refers to the usage of eco-friendly products during your period to contain your bleeding without it affecting the environment.
