Orujo (olive waste)
This article needs additional citations for verification. (June 2015)
Orujo is called the wet solid waste, which is generated by the traditional methods of extraction, based on presses, and the continuous three-phase decanting processes. The process generates additionally one stream of olive oil and two streams of wastes, the Orujo and an aqueous waste called alpechín.
