Jack Oyugi Omondi: Turning Lake Victoria’s 'Green Menace' into Gold

For decades, the shores of Lake Victoria have been besieged by a silent, suffocating invader: the water hyacinth (Eichhornia crassipes). This fast-growing weed forms impenetrable mats across the water’s surface, blocking sunlight, depleting oxygen, and bringing local fishing economies to a standstill. While most saw an environmental catastrophe, Jack Oyugi Omondi, a Kenyan biotechnologist and former dairy farm manager, saw an untapped resource. Driven by the high cost of traditional livestock feed and the sight of hungry cattle grazing on weeds despite their natural irritants, Oyugi embarked on a journey to turn a botanical nuisance into a nutritional cornerstone for African agriculture.

The journey began in 2016 at "Ground Zero" in Homa Bay County. As a dairy manager, Oyugi was frustrated by a common dilemma: the skyrocketing cost of fishmeal and soy-based feeds, which squeezed the margins of local farmers. He observed that during dry seasons, cows would instinctively graze on the hyacinth along the lake shores, though they struggled with the plant’s tough, irritating leaves. This observation sparked a multi-year research project involving the University of Nairobi and experts in the Netherlands, aimed at unlocking the plant's nutritional potential through high-tier biotechnology.

The technical breakthrough was achieved through a proprietary, patented fermentation process. In its raw state, water hyacinth contains only about 14% protein and is heavily reinforced with lignin, making it difficult for animals to digest. Oyugi’s company, Bio-fit Agritec, developed a workflow that begins with mechanical harvesting from the lake surface. The harvested biomass is steam-boiled to neutralise aquatic pathogens and weaken the cellular walls, then dried and crushed into a high-surface-area substrate. The "secret sauce" is the introduction of a specific local fungal strain that metabolises the complex carbohydrates and softens the fibrous lignose. This fermentation process effectively concentrates the protein levels, resulting in a product called Aquaprotein that boasts a protein concentration of 50% to 55%.

The impact of this innovation is twofold: ecological and economic. By removing two tons of hyacinth weekly, Bio-fit is helping restore the limnology of Lake Victoria, allowing fish to breed and transport channels to open. For the farmers, the results are even more immediate. Pilot studies in Homa Bay and Meru Counties demonstrated that cows fed with Aquaprotein-enriched meals saw a 20% increase in milk production, while the cost of feed dropped by 30%. Beyond cattle, the feed has proven effective for poultry and fish farming, providing a balanced nutritional profile that is free from the synthetic hormones found in many imported alternatives.

Bio-fit's social model is equally revolutionary. Instead of using large-scale industrial harvesters, Oyugi has contracted 20 local fishermen to collect the weed, providing a vital income stream for those whose traditional livelihoods were destroyed by the hyacinth mats. Local women are employed in the sun-drying phase, ensuring that the economic benefits are distributed throughout the lakeside communities. By-products from the process are even repurposed into organic fertilisers and soil conditioners, creating a true circular economy.

Looking ahead, Oyugi’s vision is continental. With the support of partners like the SNV Netherlands Development Organisation, Bio-fit aims to remove 10 tons of hyacinth daily and produce 100 tons of feed monthly by late 2023. Plans are already underway to expand into Ethiopia, Nigeria, Tanzania, and Uganda, nations all struggling with the same aquatic invasion. Jack Oyugi Omondi is proving that African makers don’t just solve problems; they re-architect them into opportunities for prosperity.

Lessons for Budding Makers

Jack Oyugi Omondi's journey offers valuable insights for aspiring creators and entrepreneurs:

1. Circular Economic Thinking: Instead of treating environmental waste as a problem to be disposed of, identify how its chemical or physical properties can be valorised into a high-demand market product, such as transforming an invasive weed into high-protein feed.
2. Localised Technical Rigour: Success in the "bottom of the pyramid" markets requires combining traditional observations with rigorous scientific testing; Oyugi didn't just dry the weed, he patented a fungal fermentation process to ensure safety and nutritional efficacy.
