How Phool Turned 8 Million Tonnes of Temple Waste Into India's Rs 50 Crore Sustainable Revolution

On January 14, 2015—Makar Sankranti—Ankit Agarwal sat on the banks of the Ganges in his hometown Kanpur with a visiting Czech friend. Around them, 150 devotees performed ceremonial dips in the holy river. Nearby, tonnes of temple flowers—marigolds, roses, jasmine—were being dumped directly into the water.

As sunlight refracted through the murky water, Agarwal's friend posed a simple question: "If the river is so sacred, why is it so polluted?"

The question haunted Agarwal. He'd grown up in Kanpur, witnessed this ritual thousands of times, yet never questioned it. That day, he started researching. What he discovered was staggering: approximately 8 million tonnes of flowers are dumped annually into India's rivers from temples, mosques, and gurudwaras—flowers laden with pesticides and heavy metals, slowly poisoning the waters millions consider sacred.

In 2017, Agarwal and his childhood friend Prateek Kumar co-founded Phool (initially called HelpUsGreen) to solve this paradox. By 2024, their biomaterials startup had flowercycled over 42,300 tonnes of floral waste, prevented more than 4,230 kilograms of pesticides from entering waterways, employed 324 marginalized women, and generated Rs 50 crore in revenue—growing 75% year-over-year.

This is the story of how two IIT Kanpur graduates turned religious devotion's unintended consequence into India's most innovative circular economy model.

The Founder: From Automation Scientist to Social Entrepreneur

Ankit Agarwal was born and raised in Kanpur—an industrial city on the Ganges known for leather manufacturing and, unfortunately, severe river pollution. He graduated from IIT Kanpur with an engineering degree and initially worked as an automation scientist at Symantec (now NortonLifeLock), a major software company.

Prateek Kumar, his co-founder, was an environmental engineer at Apollo Tyres. Both had stable careers, comfortable salaries, and conventional futures ahead.

But that January 2015 moment on the ghat changed everything. Agarwal couldn't stop thinking about the contradiction: offerings meant to honor the divine were destroying the sacred river. For months, he researched temple waste management, pollution impacts, and potential solutions.

The numbers were devastating. In Uttar Pradesh alone, over 8.4 tonnes of pesticide-laden flowers were dumped daily into the Ganges. The chemicals—used to grow flowers commercially—leached into water, creating toxic compounds that threatened marine life and the 420 million people depending on the Ganges.

In 2017, Agarwal made a decision that seemed crazy to family and friends: he quit his stable job to start a flower-recycling business.

The First 18 Months: When Nobody Believed

The initial period was brutal. Agarwal spent 18 months experimenting in makeshift laboratories, trying to figure out how to process flowers into something useful. The concept seemed absurd to most people—further using waste flowers appeared impractical and economically unviable.

His biggest challenge wasn't technical—it was cultural. Convincing temple authorities and priests to give up sacred flowers meant navigating faith, tradition, and deeply held beliefs. Flowers offered to gods couldn't just be "waste." Many religious leaders found the idea disrespectful.

"People were initially skeptical and felt I was wasting time," Agarwal recalls. "The idea seemed ludicrous to most."

But Agarwal's sincerity and mission-driven approach gradually changed minds. He explained that letting flowers poison the river wasn't honoring the divine—it was desecrating creation. Slowly, temple partnerships formed across Uttar Pradesh.

January 2018: The IIT Kanpur Connection

The breakthrough came through Professor Amitabha Bandyopadhyay, Professor-in-charge of the Technology Business Incubator at IIT Kanpur. Impressed by Phool's mission, he introduced Agarwal to the BIRAC-funded BioNest at the Startup Incubation and Innovation Centre (SIIC) at IIT Kanpur.

The very next day—January 2018—Agarwal gained access to laboratory infrastructure and began developing the patented "flowercycling" technology.

This partnership proved transformative. With proper facilities, Phool's team created a multi-step process: collect flowers from temples, segregate petals from stems and threads, wash petals to remove pesticides, dry them, powder them, knead into dough, roll into incense sticks, dip in essential oils for fragrance, and pack for sale.

The lab at IIT Kanpur eventually employed seven scientists working to ensure products were completely organic and chemical-free.

The Product Innovation: From Incense to Vegan Leather

Phool's first commercial product was charcoal-free incense sticks and cones made entirely from recycled flowers. Unlike traditional incense containing charcoal and synthetic chemicals, Phool's incense was natural, toxin-free, and certified organic.

Consumer response was overwhelmingly positive—drawn by natural fragrance, ethical sourcing, and environmental impact. But Agarwal wasn't satisfied with just incense.

In 2020, while developing incense, Nachiket Kuntla—Phool's head of research and development—noticed something remarkable: unused piles of flowers had developed a mat-like coating with unusual morphology.

"It had a very strange morphology. I was very intrigued by it," Agarwal explained. "Slowly, after three years of hard work, we were able to figure out this material behaves exactly like animal leather."

This discovery became Fleather—India's first plant-based, cruelty-free leather alternative made entirely from recycled flower waste. Unlike traditional leather (which involves chromium tanning and releases toxic chemicals) or plastic-based alternatives, Fleather was biodegradable and genuinely sustainable.

Phool also developed Florafoam—biodegradable packaging material made from floral waste, positioning it as an eco-friendly alternative to thermocol/styrofoam that takes centuries to decompose.

Women at the Heart

From inception, Phool centered its model on employing marginalized women—many from Dalit communities, previously forced into manual scavenging or other dehumanizing labor.

By 2018, Phool employed over 200 women across collection units in Kanpur, Tirupati, Mathura and Varanasi. By 2024, that number exceeded 324 women across five major pilgrimage towns: Kanpur, Varanasi, Ayodhya, Bodh Gaya, and Badrinath.

These weren't just jobs—they were dignity restored. Women received fair wages, safe working conditions, and social security. The company also enabled education for over 67 children from these communities.

An "office bus" picks up women daily, transporting them to clean facilities where they sort flowers, weigh waste, and process materials—far from the dangerous, dehumanizing work many had endured previously.

The Vision: India's Tesla of Sustainable Materials

Agarwal's stated vision is bold: "Make Phool the Tesla of sustainable materials—beautiful, scientific, scalable, and socially inclusive."

The startup operates at the intersection of culture, sustainability, and design—proving that solving India's problems doesn't require abandoning tradition but reimagining it.

Future plans include expanding collections to major temples nationwide, developing new biomaterial applications, and scaling Fleather production to disrupt India's toxic leather industry.

The Philosophy

"Have patience," Agarwal advises aspiring entrepreneurs. "Purpose-driven ideas often take time to gain traction. If your vision solves a real problem and is rooted in integrity, the world will eventually listen."

Phool's mission intersects three challenges: preventing river pollution, ending manual scavenging through dignified employment, and replacing toxic industries with sustainable alternatives.

The Legacy

From a question on a riverbank in 2015 to Rs 50 crore revenue in 2024, from skepticism to global recognition, from discarded flowers to vegan leather—Phool proves that India's biggest problems can become India's biggest opportunities.

When 8 million tonnes of temple flowers were dumped annually, most saw religious obligation. Agarwal saw environmental catastrophe—and business opportunity.

When women from marginalized communities faced dehumanizing labor, most looked away. Agarwal created dignified employment restoring their humanity.

When leather and packaging industries released toxins, most accepted it as necessary evil. Agarwal developed plant-based alternatives proving profit and planet aren't opposites.

The Czech friend's simple question—"If the river is so sacred, why is it so polluted?"—sparked a revolution proving that honoring tradition and protecting nature aren't contradictions. They're complements, waiting for someone courageous enough to reconcile them.

That's not just building a business. That's healing a river, empowering communities, and proving that India's circular economy solutions can lead the world—one recycled flower at a time.
