This Thesis starts from a very important problem for the society which is that of the accumulation of wastes in the environment. It has been told that the advancement of technology has given us many materials and means that make our life more comfortable but at the same time these materials, due to their excellent characteristics, when discarded affect our environment and persist for a long time without disintegrating. That is why the human being has set the task of finding ways to reduce the amount of waste and, as a way of doing so, has developed methods to recycle the valuable products from the waste. PET (Poly Ethylene Terephthalate) is one of those wonderful materials invented by man, which, unfortunately, after its use, is accumulating in the environment and therefore requires to be eliminated or, much better, recycled to re-produce the goods that all we need. This Thesis aims to study first the different methods of PET recycling, but especially its decomposition in its constituent monomers for use in the production of other goods while reducing the accumulation of their waste in nature. The Thesis studies the decomposition of the PET by means of the method of hydrolysis in acid medium and looks for the best conditions to maximize the decomposition yield. During the experimental work many tests have been developed with different reaction temperatures, concentrations and quantities of reagents, reaction times and methods of separation and it has been determined the set that lead to the highest yield in obtaining the constituent monomers. We could obtain high purity terephthalic acid and in near stoichiometric quantities, however the ethylene glycol quantities obtained were far lower than expected.
