• •Potencial of the bagasse ash is analyzed for the treatment of cooking oil.•The ash has good properties and characteristics for this application.•It was shown that the sugarcane bagasse ash decreases the acidity of cooking oil.•The residual oil treated with bagasse ash can be used for energy purposes. The adsorption potential of sugarcane bagasse ash (SBA) and activated carbon (AC) for free fatty acids in waste cooking oil has been investigated by batch technique, with different operating conditions, like temperature, adsorbent mass and agitation. AC and SBA were characterized by nitrogen physisorption, scanning electron microscope, energy dispersive spectroscopy and X-ray diffraction, to identify porosity characteristics, elementary composition and functional groups. The maximum result obtained for activated carbon, commercial adsorbent, at acidity reduction was 63%, using 22,4°C, 169,64rpm and 3,39g of adsorbent mass. Already using SBA, the higher reduction was 68%, at the same conditions, however in shorter times. The above reveals ash’s capacity in oil treatment. Since it is a by-product of burnt bagasse, with little added value and with low costs, its employment in these processes becomes an asset.
