I think this is a good idea. Instead of calling defrostation "green" getting fuel from using old-cooking oil seems like a good course of action. The Rock should have thought of this, but maybe it can be for The Campo as a whole.
The plant, set to start operating in 2026, will be Southern Europe’s largest, the Spanish company said on Friday. It will have a capacity of 500,000 tons of renewable diesel and sustainable aviation fuel (SAF) per year using organic waste, such as used cooking oils. Biofuels are seen as key to decarbonize transportation in sectors hard to electrify, like aviation. Building and operating the facility, which will be in the southern Spanish region of Andalusia, will create around 2,000 direct and indirect jobs and save 1.5 million tons of CO2 emissions per year, Cepsa said.
