With Banana Fibre, This Entrepreneur-Couple is Breaking Taboo Around Menstruation

Sparkle co-founders Chirag and Hetal Virani

Surat-based couple Chirag and Hetal Virani are on a mission – to break one of the biggest taboos in India by spreading awareness on menstruation, and improve menstrual-care through eco-friendly pads. Their startup, named Sparkle, has built biodegradable sanitary pads from banana fibre. Additionally, their ‘Buy One Give One’ initiative ensures that every time a Sparkle pad – which cost about Rs.20 – is sold, one is also sold to a woman who needs it but cannot afford it.  

To their credit, Sparkle was selected as one of top five most innovative startups in health category by one of the biggest start-up competitions in the world, Tech Crunch Disrupt, in the US last year.

Speaking to MAKERS India, Hetal spoke about her vision:

Chirag, despite the social stigma associated with a non-glamorous business like theirs, is clear about his path too. “In 2010-11, after my engineering and before doing my MBA, I went to Kenya, Tanzania, Vietnam, and quite a few other underprivileged areas where I volunteered at orphanages. I participated in medical awareness campaigns and that was the first time I was exposed to how menstruation can really affect girls’ life. I saw that since they don't have access to sanitary pads, many girls could not even go to schools. I got the inspiration to do something then,” he says.  

Hetal and Chirag co-founded an NGO, United World Foundation, in 2017, for working on women’s healthcare and educational prospects, and improving the farmer economy in rural areas. Initially, this NGO would buy pads available in the market and donate it to underprivileged women. But it was not sustainable as plastic waste is not bio-degradable. 

As environment-friendly as it gets

Chirag comes from a family of farmers who own banana plantations. Once banana is harvested (in every 9-12 months), there is no need for the stems – which are about eight feet long and 60-100 kg heavy. Since the farm has to be cleared up for the next crop, hundreds of tonnes of stems were either burnt, causing air pollution, or had to be removed from the farms at higher labour expense.

On researching how to use this agro-waste as a sustainable raw material, he found that banana fibres have been used for making sanitary pads in Africa. Chirag and Hetal decided to do something along this line, as Hetal herself was finding commercially available sanitary pads dissatisfactory, a problem faced my many users in India.

Their family was shocked when Chirag presented the idea to them – why would he do this when he has an engineering degree and MBA? But the duo was determined.

Hetal, a chartered accountant, had earlier worked with Chirag in e-tail of diamond jewellery too. Pooling in $100,000 from their savings, they started product research and development (R&D) in 2018.

Long process  

The first step to building Sparkle pads was to extract fibre from the banana stem. So the duo started with a machine that was readily available in the market. However, as a mechanical engineer, Chirag found many inefficiencies in the machine: it was too labour intensive, not cost effective, and had many safety issues.

After months of researching and spending 2-3 months at the farm, he developed a new machine to make the whole fibre extraction process efficient. Although Chirag designed the pads after wide research, Hetal rejected the first two attempts, but liked the third one. So they distributed the third model among 500 women, asking for feedback. With their input, the fourth model version eventually went to market. Within a month, they had sold around 50,000 pads.

3 birds with one stone

The duo wanted to address multiple factors: recycling agro-waste, removing the taboo around periods, and reducing plastic pollution.

According to Chirag, India has 800,000 hectares of banana plantation and they generate 65 million tonnes of agro-waste. Once the R&D stage was over, the duo started collecting agro-waste from the farmers in banana plantations in the region near Narmada river.

“We buy the agro-waste at a nominal cost. Earlier it was an expense for the farmers; now it is an income. So far we have processed more than 500 tonnes of banana stems. We're also filing patents for these machines,” says Chirag.

Conventional pads contain up to 90% plastic, with the top layer made of polypropylene, bottom layer with polyethylene, and in the centre there is sodium bicarbonate. They take about 600 to 800 years to degrade in the landfill after disposal. In Sparkle pads, the top layer made of bamboo fibre, naturally antibacterial and very soft, and the bottom layer is made from corn starch. The base is an absorbent material made from the agro-waste. Chirag claims that the entire composition of the pad degrades in six months.

“In India, just one in six women are using pads today; so 150,000 tonnes of pad-waste is generated per year. And if all of 350 million women (of menstrual age) start using the pads, that will result in around a million tonne of pad waste.”

Reaching out

Conventional, commercially available plastic-based pads are sold at Rs.7-13, and most biodegradable pads (both domestic and foreign ones) are priced between Rs.18 and Rs.35.

To make their product accessible to the masses, Sparkle will soon launch a new version which costs Rs.10 per piece, with different packaging and layers. It is 100 percent biodegradable too, says Chirag, adding that the R&D was conducted in collaboration with multiple hospitals and gynaecologists, and their outreach is conducted by collaborating with multiple NGOs.   

“Many investors and social enterprises they've approached us in terms of how they want to be part of us. There are no short cuts for success; our journey has only begun,” Chirag signs off.
