The increase of population demands more food, another important issue. In most countries the soybean oil is widely used as cooking oil. The incorrect disposal of waste cooking oil represents a threat to environment, and to human health. This paper evaluates the Brazilian bentonite modified by acid attack in the ceramic filter manufacturing aiming to use in waste cooking oil recycling. The cylindrical and prismatic samples were calcined, and the characterization tests were performed: porosity, density, mechanical strength; DRX, CEC, XRF, SEM/EDS, specific surface area (BET), stereomicrography; spectrophotometry and bleaching capacity. The Brazilian bentonite sample modified by acid attack presented a good potential for ceramic filter manufacturing.
