Kenya Airways and Rubis Energy Kenya have signed a memorandum of understanding to develop what they say would be Africa's first dedicated sustainable aviation fuel refinery.

The refinery is expected to have a production capacity of 32,000 metric tonnes, with a project investment estimated at 60 to 70 million euros ($70.5 million to $82.2 million), the two companies said in a joint statement.

The agreement was signed in the presence of Kenya's President William Ruto and President Emmanuel Macron of France on Tuesday, the companies said.
