Synthetic Manure

"The synthetic cow copies the real animal almost completely, and it even eats the same organic food. However, despite the high quality of work of the waste processing systems, there's still much waste produced by the cows after eating such food. This manure was widely used as cheap fuel, but now it's mostly used for making facial masks."

Can be found primarily in the biolaboratory area not far from the engine wreckage. Look for white debris.
