Chemical recycling of municipal packaging waste by pyrolysis

[EN]The present doctoral thesis centers on studying pyrolysis as a chemical recycling technique for rejected packaging waste fractions coming from separation and sorting plants. The pyrolysis experiments have been carried out in a lab-scale installation equipped with a 3.5 L semi-batch reactor and a condensation and collection system for the liquids and gases generated. In the present thesis, an experimental study on the conventional pyrolysis process applied to the aforementioned waste fractions has been conducted, as well as the study of non-conventional or advanced pyrolysis processes such as catalytic and stepwise pyrolysis. The study of the operating parameters has been carried out using a mixed plastics simulated sample, the composition of which is similar to that found in real fractions, and subsequently the optimized process has been applied to real packaging waste. An exhaustive characterization of the solids, liquids and gases obtained in the process has been made after each experiment and their potential uses have been established. Finally, an empirical model that will predict the pyrolysis yields (% organic liquid, % aqueous liquid, % gases, % char, % inorganic solid) as a function of the composition of the initial sample has been developed. As a result of the experimental work done, the requirements have been established for an industrial packaging waste pyrolysis plant that aims to be sufficiently versatile as to generate useful products regardless of the nature of the raw material.

Rumbo al Gran Banco: una etnohistoria de la pesca industrial del bacalao en los Bancos de Terranova

[ES]Rumbo al Gran Banco parte de los comienzos de la pesca industrial del bacalao española en el primer tercio del siglo XX, la situación que allí encontraron, los avatares humanos y los avances tecnológicos que se van incorporando, la Guerra Civil y la guerra mundial, la bonanza pesquera, la incorporación de las parejas, la concurrencia, así como la exploración de todo el Gran Banco. La gestión por parte de Canadá de las doscientas millas marinas y la moratoria del bacalao. También se presenta la historia de la pesca en Galicia y Terranova a lo largo de todo el siglo XX, dos territorios que comparten el mismo océano y una mirada puesta en la mar.
