Hong Kong's Green Jet Fuel Push: Kitchen Waste Feedstock, High Costs, and Supply Chain Hurdles

Hong Kong is pushing for sustainable aviation fuel, but the economics are difficult. Biofuel producer EcoCeres is sourcing used cooking oil, once known as gutter oil, across the Greater Bay Area. That waste now costs more than conventional fuel, which makes SAF expensive before it even reaches an aircraft. The article examines how Hong Kong can scale SAF supply chains and whether airlines can pass costs to passengers. It also looks at the gap between policy goals and available feedstock. For anyone tracking low-carbon fuel policy or biofuel project finance, this is a useful look at the real constraints.

Interesting piece on SAF feedstocks. The part about gutter oil now costing more than fuel says a lot about supply and demand. Worth a read if you follow biofuel economics. Would like to know how much of Hong Kong's aviation fuel demand this could realistically cover.

The feedstock economics are brutal. If waste oil is more expensive than the fuel it replaces, SAF only works with policy support or a price on carbon. Article doesn't dig into which mechanism Hong Kong is leaning on.

As an aviation fuel story, the bottleneck is supply chains and cost, not the tech. The article mentions EcoCeres but not the actual production capacity or how much SAF Hong Kong could source from GBA waste. That's the number that matters.

SAF mandates are the usual answer, but they push costs onto airlines and then passengers. The piece asks if travelers will pay, which is the right question. Hong Kong has no clear carbon price for aviation, so expect a lot of voluntary offset noise until a rule forces the issue.

Not my usual area, but the same pattern shows up in building retrofits: when feedstock or labor costs spike, the project math falls apart. The article could use a breakdown of SAF cost per litre vs fossil jet fuel, not just anecdotes.
