Abstract
The current energy scenario requires studies and efforts to develop innovative technologies in a sustainable manner, with respect to optimize the use of renewable and non-renewable energy sources. More specifically, it is noted nowadays an exaggerated consumption and consequent accumulation of plastic residues derived from petroleum. Plastic, one of the symbols of disposable consumer society and one of the most common constituent of garbage, has the following characteristics: low cost, low weight, good mechanical endurance, impermeable, transparency, durability, staining capacity. Such characteristics provide irresistible triumphs for its use in several important applications in society. But, their residues cause considerable problems in the world, due to its large volume and the difficulty of treatment. Thus, alternatives and strategies recycling’s and recovery of post-consumer plastics are being developed to reduce the impact created, such as: landfill, physical recycling and thermochemical recycling (incineration, gasification, liquefaction and pyrolysis). The pyrolysis consists of a thermal decomposition in the absence of oxygen, typically used in some industrial processes, such as: charcoal production and polymers formation. But with the recent panorama, there is a growing interest in the application of this process in solids residues to generate fuel and raw materials for chemical industries. Thus, it is proposed in this work to research and develop an equipment to carry out the pyrolysis of plastics residues in order to extract its by-products: condensable and non-condensable gases. In a broader sense, it is proposed to develop new technologies for energy recycling from plastic residues in order to give a correct destination to the hydrocarbons intrinsic to its structure.
