Assam-based startup Kumbhi Kagaz Pvt. Ltd. is proving that one of the world’s most invasive aquatic weeds can become a powerful solution for environmental sustainability. Founded in 2022 by Rupankar Bhattacharjee and Aniket Dhar in Guwahati, the venture transforms water hyacinth into eco-friendly handmade paper, reducing pressure on forests while helping restore wetlands.
By converting an environmental menace into sustainable stationery products, the startup is creating livelihoods, promoting a circular economy, and demonstrating how innovation can address ecological challenges.
What began as an idea to tackle Assam’s growing water hyacinth problem has evolved into an award-winning enterprise. The company has processed more than 92 tonnes of water hyacinth, generated over ₹20 lakh in sales, secured grant funding, and earned national recognition, including a mention in Prime Minister Narendra Modi’s Mann Ki Baat, for its innovative waste-to-resource model.
From Invasive Weed to Sustainable Innovation
Water hyacinth is among the world’s most invasive aquatic plants, rapidly spreading across lakes, rivers and wetlands. In Assam, it has severely affected ecosystems such as Deepor Beel, the state’s only Ramsar site, by choking water bodies, reducing oxygen levels, disrupting fishing, obstructing irrigation and threatening biodiversity.
Instead of viewing the weed as waste, Kumbhi Kagaz developed a sustainable alternative. The startup manually harvests water hyacinth, extracts its natural fibres and transforms them into tree-free, chemical-free handmade paper through an eco-friendly production process.
The handmade sheets are then crafted into notebooks, journals, calendars, conference pads, greeting cards and other stationery products, offering a sustainable alternative to conventional paper while reducing dependence on wood pulp.
Building Livelihoods While Restoring Wetlands
Beyond producing eco-friendly paper, Kumbhi Kagaz has built a circular economy that benefits both people and the environment. The company works with local communities to collect and supply harvested water hyacinth, creating additional livelihood opportunities while helping clear invasive weeds from wetlands and waterways.
Its zero-waste approach ensures that discarded biomass is transformed into valuable products instead of ending up in landfills or water bodies. Over time, the initiative has contributed to wetland restoration, encouraged sustainable resource use and demonstrated how environmental conservation can go hand in hand with entrepreneurship.
The startup’s innovative approach has received recognition through national and international platforms, including WasteAid UK’s Zero Waste Cities Challenge, while its mention in Mann Ki Baat brought wider attention to its efforts in sustainable manufacturing and environmental conservation.
The Logical Indian’s Perspective
At The Logical Indian, we believe Kumbhi Kagaz highlights how local innovation can turn environmental challenges into opportunities for sustainable development.
Looking ahead, Kumbhi Kagaz aims to expand its production capacity and collaborate with more communities across Assam and beyond to scale its sustainable paper-making model. By encouraging the use of invasive biomass as an alternative raw material, the startup hopes to reduce dependence on conventional wood-based paper while promoting responsible consumption and environmental stewardship.
Its journey illustrates how locally driven innovation can create scalable solutions that benefit both people and ecosystems, offering a blueprint for sustainable entrepreneurship in India.
By transforming an invasive weed into handmade paper, the startup has created a model that supports conservation, generates rural livelihoods and promotes responsible production without relying on tree-based raw materials.
As India works towards a more sustainable and circular economy, initiatives like Kumbhi Kagaz demonstrate that meaningful environmental solutions often begin at the grassroots. Supporting such innovations can help restore fragile ecosystems while encouraging businesses that prioritise both people and the planet.
