Idea description

Spanish startup Souji

This is the first formula based on mineral and vegetable compounds that, when mixed and shaken in the correct proportions with waste oil, provide a saponification reaction (the chemical process by which the fatty body together with the base forms soap) in just 1 minute, without the need for heating and without any heating or corrosive agents such as caustic soda.


  • Secondary recycling


The startup offers soap and detergents made from recycled vegetable oil. The detergent is suitable for use in washing machines or hand washing, as well as for cleaning floors and dishes.
