From waste to wealth: Farmer turning maggots into millions

In the quiet town of Karatina, Nyeri County, an agricultural revolution is quietly brewing, one that is transforming waste into wealth through an unlikely hero: the Black Soldier Fly (BSF).

At the forefront of this change is Patrick Maina, the founder of Flourish Farm Ventures, who has turned his vision of eco-conscious, sustainable farming into a thriving enterprise that’s capturing national attention.

Maina’s journey into BSF farming began with a desire to explore an untapped niche in agribusiness.

“We wanted to pursue a unique agribusiness idea that wasn’t saturated in our community, something sustainable, affordable, and profitable,” he reflects.

With traditional feed costs rising, he saw the potential in BSF farming, an approach that utilises larvae to convert organic waste into high-protein feed for livestock, pigs, and fish.

After training at a BSF farm in Othaya, Maina returned to Karatina to launch Flourish Farm Ventures.

His enterprise now supplies larvae to other farmers and provides hands-on training to equip aspiring agripreneurs with practical skills to build their own BSF farms.

The BSF training programme is comprehensive, covering everything from the fly’s life cycle and breeding to managing larvae and extracting value from by-products.

For Ksh 10,000, each trainee receives structured lessons, demonstrations, and personalised mentorship.

“Knowledge is power,” says Maina. “Training helps new farmers avoid costly mistakes and fast-tracks their path to success.”

Targeting youth and farmer groups keen on sustainable agriculture, Flourish Farm relies on social media platforms like Facebook, YouTube, and WhatsApp to spread the word.

Maina also hosts virtual training sessions to accommodate learners from distant counties.

But the journey hasn’t been without hurdles. “Our biggest challenge has been finding reliable and skilled workers,” Maina reveals.

Inconsistent labour and limited capital have slowed expansion, particularly the setup of a cost-effective mechanised system for processing larvae.

This, in turn, affects the supply of BSF-based dairy cow and animal feed, which remains costly and limits uptake.

Still, the potential is immense. Beyond producing feed and organic fertiliser, Maina is exploring the BSF value chain, from selling BSF materials for use in animal feed to processing waste into oils and chitin, a valuable resource in pharmaceuticals.

“BSF farming is a powerful model of circular agriculture,” he explains.

On a good month, Flourish Farm Ventures generates over Ksh 120,000 in revenue, with increasing demand for both larvae and training services.

Maina’s vision, however, stretches far beyond profit. He believes that with the right support, BSF farming can uplift Kenyan youth, provide sustainable income, and drive food security.

“We need support in acquiring machinery and expanding infrastructure to make BSF products cheaper and accessible,” he appeals to stakeholders. “Partnerships with NGOs, government, and private investors are key.”

Maina’s parting message is as bold as his venture: “Ukulima sio ushamba. BSF farming is not only a game-changer in agriculture, it’s a livelihood multiplier. For Kenyan youth and farmers looking for a sustainable income source, this is a goldmine in disguise.”
