The growth in the generation of the waste of electrical and electronic equipment (WEEE) has won global importance. Cell phones are highlighted between these wastes because of its short life cycle and its great amount of hazardous materials. Thus, this work aims to obtain an effective method for indium extraction from liquid crystal displays (LCD) screens of cell phones using alternative organic acids. For comparative purposes, leaching tests are performed with supercritical CO2 and co-solvents, as well as under conventional conditions using citric and malic acids. The results showed that at atmospheric pressure, 76.5% of indium was extracted after 180 min. The use of supercritical CO2 besides providing a reduction in extraction time also provides a higher extraction, reaching 94.6% in just 30 min. In summary, a novel method for indium recovery was developed. Furthermore, the process was more efficient using supercritical CO2, increasing the extraction and turning the process 6 times faster than conventional extraction. (C) 2016 Elsevier B.V.
