Kristin Kagetsu left the United States in 2014 with an idea: to bring sanitary pads to India. The 27-year-old MIT graduate co-founded Saathi Pads - a health care startup that produces biodegradable sanitary pads made of banana fibers. According to a 2011 study ... only 12% of Indian women use sanitary pads during menstruation. Tampons, menstrual cups and reusable pads are practically unheard of, except in elite circles. Affordability is the key factor preventing many women from using sanitary pads. For lower income families, they can be a luxury. Saathi Pads said it plans to sell its product ... online and in urban areas but will distribute them for free in rural areas, or at heavily subsidized rates. The lack of proper feminine hygiene and sanitation facilities can affect women's productivity at work and in school. More than 30% of girls interviewed in northern India dropped out of school after they started menstruation. Kagetsu and her co-founders ... decided to manufacture their own compostable sanitary pads using banana fibers, a byproduct of fruit production. The pads Saathi produces are biodegradable and can be upcycled to compost or biogas after use. The company claims its production process is completely chemical and plastic free. The company's purchase of agri-waste material also helps provide banana growers with additional income.
