Where there are people, there’s potential.
Used Cooking Oil (UCO) begins in the same place as most meals: the kitchen.
Collected from restaurants, food processors, and industrial kitchens, it’s one of the few truly global waste streams.
Wherever people cook, there’s UCO.
At Connex, we work with this material every day. It’s not a product we sell – it’s a system we manage to keep materials flowing efficiently and waste under control.
Because UCO is not grown or produced for energy, it represents genuine circularity: we recover, refine, and redirect what already exists.
From fryer to fuel
The origins of UCO connect directly to the history of diesel itself. The first diesel engines were designed to run on fuel made from peanut oil and lard, which are the same kinds of fats UCO contains today.
That chemistry makes UCO naturally suitable for renewable fuel production, from biodiesel to HVO and SAF. Still, each batch comes with its own character. Levels of saturation can affect processing performance, leading to wax formation or polymeric residues if not handled correctly. No batch of UCO is the same; each kitchen cooks differently, and the quality of its UCO is unique to its practices.
This is where expertise matters. Through controlled blending and detailed analysis, we ensure a consistent, processable feedstock. That’s how waste becomes a reliable input for advanced biofuel production.
Greater impact
UCO is a supplement, not a replacement – it won’t fix our dependence on fossil fuels, yet it offers something real: a working option that reduces emissions today while bigger solutions scale tomorrow.
At Connex, progress means action. Every tonne of UCO we move, test, and supply turns intent into impact, closing the gap between current demand and future responsibility. Together with our partners, we turn that progress into consistent supply chains, measurable reductions, and real operational value.
