Global used cooking oil (UCO) supply is expected to increase from 14bn litres (3.7bn gallons) in 2022 to 18.9bn-37.8bn (5bn-10bn gallons) by 2030, according to a new report by US trade association Clean Fuels Alliance America.

Meanwhile, US supply could increase from 3.2bn litres (850M gallons) to 4.1bn litres (1.1bn gallons) by 2030, according to report authors LMC International and GlobalData.

“Growing demand for … cleaner fuels like biodiesel, renewable diesel and SAF is creating an … opportunity to develop additional supplies of low-carbon fats and oils, including used cooking oil and surplus crop oils,” Donnell Rehagen, CEO of Clean Fuels Alliance America, said in the 13 September report.

“Our industry envisions sustainably producing 22.7bn litres (6bn gallons) of clean fuels by 2030, and this report identifies crucial additional feedstocks. Our vision supports national goals to decarbonise aviation and other heavy-duty transportation sectors.”

The USA has the most well-developed UCO collection system, due to long-standing practices for its use and disposal, according to the report.

Increasing biodiesel and renewable diesel production in the USA was boosting domestic UCO use – curbing recent export trends, the report said.

According to the report, most UCO supplies are transported from Asia to Europe and there is potential to increase UCO collection in Asia, Europe and South America to meet global demand.

Additional collection could be achieved in those countries with the adoption of US-style collection practices, the report said.

Clean Fuels Alliance America represents the biodiesel, renewable diesel and SAF sectors in the USA.
