China’s Used Cooking Oil Ships to US as War Drives Biofuel Boom

American imports of used cooking oil from China are set to accelerate as increased US biofuel-blending requirements kick in and the Iran war drives up energy costs, making the feedstock a relative bargain.

Two cargoes carrying a combined 339,000 barrels of so-called UCO arrived in the US in the last month or so, according to Kpler data. The supplies represent the biggest imports this year, with about half of it delivered to Port Arthur, Texas, where Valero Energy Corp. partners with Darling Ingredients Inc. at the Diamond Green Diesel facility.
