Madafu Bio collects used cooking oil from kitchens across Kenya and supplies it to biorefineries, where it becomes biodiesel. Waste stays out of drains and landfills — and displaces fossil fuel instead.
Vegetable oil and fat consumed in Kenya each year — roughly 40% of it ends up as waste.

Market Data Forecast, 2025We handle the part that's hard for everyone else: getting oil out of thousands of small kitchens, keeping it clean, and delivering it at a volume and quality refineries can use.
We supply sealed containers to restaurants, hotels, food processors and institutional kitchens, and collect on a schedule that fits how fast you actually fill them.
Oil is filtered, tested and aggregated into refinery-grade batches, with every collection documented so the material stays fully traceable back to source.
Batches are supplied to biorefinery partners, who convert them into biodiesel — a drop-in fuel that replaces diesel refined from crude oil.
Poured down a drain, it congeals and blocks sewer lines. Dumped on open ground, it contaminates soil and water. Resold informally, it re-enters the food chain. Collected properly, the exact same oil becomes one of the lowest-carbon liquid fuels available — because the carbon in it has already done a job before it's burned.
That's the whole idea behind Madafu Bio: no new land, no new crops, no competition with food production. Just a waste stream that already exists, routed somewhere better.
Restaurants, hotels, bakeries, food processors, schools and hospitals — anyone running a fryer.
Reliable feedstock supply out of Kenya, with the paper trail your compliance team needs.
Madafu Bio is a Kenyan circular economy company. We exist because a valuable, low-carbon resource is being thrown away every day in kitchens across the country — and because the infrastructure to capture it doesn't really exist yet.
We're early, and we're building deliberately: strong relationships with the kitchens we collect from, clean documentation from day one, and a network that can scale without losing traceability. Environmental impact is the point, not the marketing.
Whether you've got oil to hand over or you're looking for supply, send us a note and we'll get back to you.
