Fuel has been obtained by recycling waste and/or polluted multilayer packaging beverage (WMP) through microwave assisted pyrolysis (MAP). WMP are composite materials manufactured using layers of paper, polyethylene (PE), and aluminum (Al). MAP was performed at a frequency of 2.45 GHz, a microwave (MW) power of 3 kW, using different MW absorbers (none, chopped tire, carbon, and iron powder) and apparatus set-ups. Paper was pyrolyzed to a bio-oil containing water, alcohols, aldehydes, acids, and anhydrosugars accordingly to pyrolysis conditions. PE was converted into a high viscosity liquid, solid at room temperature, except when a fractionating system was directly connected to the pyrolysis oven. In this conditions linear alkanes, alkenes, cyclic, and aromatic hydrocarbons were present in the liquids. Al was always recovered as unscratched samples. (C) 2014 Elsevier Ltd. All rights reserved.
