I think she got the idea from Ananya Maskara in Deli
This 16-Year-Old Delhi Girl Empowers Hundreds With Biodegradable Sanitary Pads:
The first time I heard about Ananya Maskara was through her grandmother at a school fete. Ananya’s grandmother sat at a stall urging everyone who was walking past to come and buy scented candles.
She said,
“I am selling these to help my granddaughter. She uses the proceeds from these sales to supply bio-degradable sanitary napkins to girls from underprivileged backgrounds.”

Or watching Padman:
The movie “Padman” - which depicts one of Hindi cinema’s most popular action heroes, Akshay Kumar, wearing a sanitary pad - has generated debate over the taboo subject in India.
The Congress party - which governs the state - has promised free pads to students in government colleges and to scrap the current tax on them.
Campaigners say it is important to make pads more widely available as girls are often forced to stay at home during their periods because they cannot afford them, while also facing stigma and a lack of toilets in schools.
The ruling Bharatiya Janata Party (BJP) has vowed to give free sanitary pads to students and the poor, and to fix the price at 1 rupee (1 U.S. cent) for all women if voted to power.

There's a number of NGOs in India supplying education concerning menstruation an associated health issues:
Pad ‘organisations’ working to bring menstrual health, hygiene to women across India
If reports are to be believed, due to lack of awareness and poverty, thousands of menstruating women/girls don't use sanitary napkins in India. Instead, they use rags, ashes and husk sand. Thus, incidents of Reproductive Tract Infection (RTI) are very common among these women. The National Family Health Survey (NFHS) 2015-16 report shows that the use of sanitary napkins among Indian women is 48.5 per cent in rural, 77.5 per cent in urban and 57.6 per cent total. Reports say in India, 24 per cent teenagers are forced to skip their schools owing to menstruation.
