Olive oil production generates olive by-products: pomaces (solid waste) and olive mill wastewater (liquid waste). The latter are a source of pollution for the environment; they are very harmful to the quality of water, soil and even air. Therefore, causing damage to environment which will affect humanity. Thus, the need for their treatment or recovery is necessary. The present inquiry aims at valorizing these margins in the field of cold soap production. The choice of the cold method is due to its ability to maintain the performance and characteristics of each oil used. Analyses show that the mixture of sodium hydroxide (NaOH), 40% of olive oil wastewater (oleic acid) obtained by natural decanting of olive mill wastewater, 30% of olive oil, 20% of cocoa oil and 10% of castor oil make a soap with a neutral pH and recommended criteria in the cosmetic field, which will lead to better results.

Abstract
Olive oil production generates olive by-products: pomaces (solid waste) and olive mill wastewater (liquid waste). The latter are a source of pollution for the environment; they are very harmful to the quality of water, soil and even air. Therefore, causing damage to environment which will affect humanity. Thus, the need for their treatment or recovery is necessary. The present inquiry aims at valorizing these margins in the field of cold soap production. The choice of the cold method is due to its ability to maintain the performance and characteristics of each oil used. Analyses show that the mixture of sodium hydroxide (NaOH), 40% of olive oil wastewater (oleic acid) obtained by natural decanting of olive mill wastewater, 30% of olive oil, 20% of cocoa oil and 10% of castor oil make a soap with a neutral pH and recommended criteria in the cosmetic field, which will lead to better results.

Abstract: (french)
La production d’huile d ’olive génère de sous-produits oléicoles: les grignons d’olives (déchets solides) et les margines (déchets liquides). Ces dernières présentent une source de pollution pour l’environnement, elles sont très nocives pour la qualité de l'eau, du sol et même de l’air, ce qui nécessite de les traiter et/ou de les valoriser.Ce travail a pour objectif de valoriser les effluents liquides (les margines) dans le domaine de fabrication des savons de type froid, le choix de la méthode froid dû à sa capacité de conserver les performances ainsi que les caractéristiques de chaque huile utilisée. Les analyses montrent que le mélange d’hydroxyde de sodium (NaOH), de 40% d’huile des margines (acide oléique) obtenu par la décantation naturelle des margines, 30% d’huile d’olive,20% d’huile de cacao et 10% d’huile de ricin permet de fabriquer un savon a un pH neutre et a des critères recommandés dans le domaine cosmétique.
