Under the Wind2Water project, India’s green vessel startup  (Guwahati) has trialed a patent-pending catamaran built from discarded wind turbine blades as a solution for the circular economy. With more than 43 million metric tons of wind blade waste expected globally by 2050 according to research from Cambridge University — India alone is projected to generate 25,000-30,000 tons annually by 2030 — the company’s Wind2Water technology re-engineers end-of-life (EOL) blades into modular hulls, pontoons and docks. The approach reduces landfill disposal costs for wind firms while creating affordable, low-maintenance vessels for inland and coastal transport.

Extensively tested on Deepor Beel, near Guwahati, the four-person prototype has proven stable, maneuverable and robust — offering what the company believes is a direct pathway to converting a mounting waste stream into safe, affordable vessels for the global south and environmentally conscious buyers worldwide. The hulls of this vessel are repurposed from the tip section of a wind blade, while the frames and the deck are comprised of bamboo composites.

“Every wind turbine blade is an environmental disposal headache in the waiting,” says Ravi Jyoti Deka, founder of Akvotransiro. “We have shown they can be re-engineered into reliable working boats that not only address waste, but also provide the water transport solutions that developing countries urgently need. This is not a concept note; it is a working vessel ready to scale.”

Founded in 2020 and supported by the Technology Innovation Hub at IIT Guwahati, Akvotransiro is reported to be India’s first startup dedicated to green, affordable water transport solutions. The company has developed BamBateau bamboo composite boats, creating unsinkable flood-rescue craft, lightweight fishing canoes and an 18-passenger river trimaran. Its bamboo composite process is a proven, production-ready sustainable boatbuilding technology. Wind2Water extends this legacy, demonstrating how EOL blades can be transformed into modular hulls, floating docks and pontoons.

According to Akvotransiro, the Wind2Water project extends the working life of discarded blades by 10-15 years, without energy-intensive recycling. It addresses a pressing waste challenge while creating safe, affordable vessels that could revolutionize inland and coastal transport worldwide. The Wind2Water proposal was a finalist in the EU’s Horizon 2020 EIC program, but could not advance due to country restrictions. Now, with full-scale trials in India, the concept has moved decisively from theory to practice. End products in development include:

• 24-36-meter multipurpose catamarans (up to 25 tons displacement) for inland and coastal transport
• 10-12-meter catamarans, pontoon boats and trimarans built from blade sections
• Low-carbon floating docks and jetties derived from turbine blade stems.

Akvotransiro’s solutions target wind energy companies, which are currently paying up to €18,000 per 10-metric ton blade for co-processing in cement plants or €5,000 for landfill disposal. They are also well suited for inland water transport operators in developing nations, where blade-derived hulls can be built at one-third to one-quarter the cost of conventional vessels and shipped worldwide for on-site assembly.

The company is currently seeking global partners across the wind energy sector to advance to the next stage: Building a full-scale 12-38-meter multipurpose catamarans and scaling its Wind2Water technology internationally.
