Due to the increase of municipal solid waste (MSW) as the population and their consume increase, new technologies of waste removal have to be developed, in order to find a MSW disposal method which do not fill lands and neither pollute the environment. Therefore, pyrolysis is raised as a way of MSW removal which at the same time can produce profitable products. This thesis is aimed at measuring the yields obtained from a pyrolysis process from different MSW mixtures, as well as the influence of temperature on the product yields is determined. For this purpose, a characterization of MSW components and the resulting products has been carried out by means of thermogravimetric, calorimetric and elemental analyses. After a quick introduction to the MSW production as well as the nowadays technologies of removal, the description of the equipment used during experimentation and discussion of results, the thesis arrives to final conclusions, where an overall view of the results is done.
