Several women’s cooperatives produce argan oil, providing an important socioeconomic function in the areas where the tree grows. It is estimated that this production of argan oil currently supports about 2.2 million people in that region.

Manual production of argan oil begins by removing the soft pulp of the fruit for use in animal feed. Then, the hard nut is cracked by hand between two stones to remove the seeds. They are then roasted and ground to a paste with a little water. This paste is hand-squeezed to extract the oil. The remaining paste is used as animal feed, so there is little to no waste in the process.
