When life hands you an invasive plant species choking entire ecosystems, why not turn it into a solution for one of the planet’s most pressing problems — plastic pollution?
That’s exactly what Kenyan entrepreneur Joseph Nguthiru did when he founded HyaPak Ecotech Ltd., a company turning the notorious water hyacinth into biodegradable packaging. What began as a frustrating experience on a university field trip is now a testament to the transformative power of innovation — proving that environmental challenges can become opportunities in the hands of a determined visionary.
THE PROBLEM: AN UNSTOPPABLE GREEN MENACE
Water hyacinths might look harmless on the surface, with their delicate purple blooms and lush green leaves, but beneath the surface, they are a menacing force. Dubbed the “world’s most widespread invasive species“, these plants form dense mats on freshwater lakes, blocking sunlight, depleting oxygen, and strangling aquatic ecosystems.
In Kenya, the invasive species has wreaked havoc on Lake Naivasha, a freshwater lake critical to both biodiversity and local livelihoods. In 2021, Nguthiru learned just how disruptive the plant could be when his boat became trapped in the lake’s thick layer of hyacinths — for five grueling hours. Instead of simply cursing the problem, he set out to solve it.

A BRILLIANT SOLUTION: FROM PEST TO PACKAGING
As part of his final year project at Egerton University, where he studied civil and environmental engineering, Nguthiru developed a method to transform dried water hyacinth into biodegradable bioplastic. The resulting product is a game-changer — tackling two environmental crises at once by reducing plastic pollution and removing invasive plants from vital ecosystems.
His company, HyaPak Ecotech Ltd., uses a proprietary process to blend dried hyacinth fibers with binders and additives, creating packaging materials that break down in just a few months. It’s the kind of innovative thinking that makes you wonder — why hasn’t anyone thought of this before?
A TIMELY INNOVATION FOR KENYA’S PLASTIC BAN
Kenya instituted a nationwide ban on single-use plastic bags in 2017, setting an ambitious precedent for environmental protection. However, the ban came with its own challenges — affordable, sustainable alternatives were in short supply, leading many to smuggle plastic bags from neighboring countries.
Nguthiru’s bioplastic could fill this gap, offering a locally sourced, fully biodegradable option for packaging. He believes his invention is truly “killing two birds with one stone” — cleaning up lakes while providing a much-needed alternative to harmful plastics.
“Most single-use plastic products tend to have a lifespan of about 10 minutes after they come out of supermarket shelves,” Nguthiru told CNN. “So why not make them biodegradable?”

WHY THIS INNOVATION MATTERS FOR THE FUTURE OF SUSTAINABILITY
Nguthiru’s bioplastic has the potential to revolutionize both waste management and invasive species control. By turning environmental threats into valuable resources, his work could inspire a whole new wave of circular economy innovations — where waste isn’t just minimized but actively repurposed.
His achievements haven’t gone unnoticed. In 2023, Nguthiru was named an Obama Foundation Africa Leader, an honor that recognizes emerging leaders across the continent making a positive impact in their communities.
