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.

The impacts of leadership in the quality of municipal public services: case study of a portuguese municipal council

[EN]The present research work, based on some of the components of the Common Assessment Framework, sets to analyse the influence held by leadership in specific factors that constitute the organisational climate, and also the impact that these factors have on the quality of municipal public services. For the purposes of this study, we propose Likert’s exploitative autocratic and participative leadership styles to explain the genesis, structure and workflow. As far as the organisational climate is concerned, the variables used are motivation, satisfaction, empowerment, conflict and stress. The main conclusions that arose was that a participative leader confers higher relevance to the quality of service, through motivation, satisfaction, empowerment and human resources positive results, than an exploitative autocratic leader. Performed contributions are based on the empiric research hereby presented, and new research guidelines are proposed. The research methodology used was qualitative, based on the case study.

An austerity-driven energy reform

In July 2013, the government approved a major overhaul of the Spanish electricity sector to correct existing imbalances that have led to an exponential increase of regulated electricity costs and a huge tariff deficit. The reform addresses the problem of financial sustainability of the sector, severely affected by weak demand and overcapacity. Previous regulation introduced in 2012 and early 2013, also aimed at restoring financial stability of the sector, failed to correct the tariff shortfall and new regulatory measures were needed to reduce the 4.5 billion euros forecasted deficit for 2013. The frequent change of the rules of the game in the sector has created regulatory uncertainty, more so as it is not clear that the present reform will be sufficient to eliminate the deficit. Moreover, the government has left the door open to new regulation that would deal with the price formation system. In general, short run financial criteria have prevailed, while efficiency principles and a long run perspective have little weight in the reform.

Reform of Spain's profesional services market: Implementation of the EU Services Directive

The implementation of the European Commission Services Directive initiated the modernization process of services markets within the European Union. The objective was to guarantee the creation of a single market by ensuring the freedom of establishment and circulation. The transposition of the Directive in Spain triggered an initial wave of reforms in the Spanish legal system. A second package of reforms is currently underway, following recommendations by the EC, IMF and OECD, which highlight the relative lack of competition in Spain’s services as one of the major imbalances in its economy, alongside the public deficit and unemployment. Both the implemented and planned reforms represent a major step forward. Nevertheless, the government has recently announced modifications to the draft bill of the Professional Services and Associations Law, which is expected to soon be submitted for parliamentary debate and approval. Taking into consideration modifications already introduced, together with anticipated further changes, it will be important to maintain the main points of the draft bill and to introduce a deeper review of the legal framework for professional services, of the professional associations themselves, and for the activities that are subject to compulsory membership within a professional association. Spain’s territorial map of professional associations must too be redrawn.

Reposición de la Red Básica Municipal de Donostia/San Sebastián

En el presente Trabajo Fin de Grado, se trabajará sobre la Red Básica Municipal de Donostia/San Sebastián, donde el autor ha sido partícipe en la campaña de reposición de la Red. Nos remontaremos a los orígenes de la Red, explicando cómo nació la Red Básica Municipal de Donostia/San Sebastián y la metodología que se usó para los trabajos previos a su implantación. A lo largo del trabajo, se explicará la metodología de observación y cálculo que se ha empleado en la actual reposición de la Red, el cual ha sido desarrollado por la empresa Geograma S.L. para el Ayuntamiento de San Sebastián entre enero y mayo de 2014. Finalmente, se estudiará como metodología alternativa las observaciones RTK en Red (NRTK), con el fin de validar el método para trabajos de observación de Redes Urbanas de Referencias Topográficas.

Estudio empírico homologable del Servicio Municipal de Deportes de Santurtzi

[ES] En este trabajo presentamos un estudio empírico homologable del Instituto Municipal de Deportes de Santurtzi, en el cual se analizan las características y evolución del deporte en este municipio, el nivel de autofinanciación del servicio, el conocimiento de las diferentes instalaciones deportivas, etc. En definitiva, el estudio trata de profundizar en la gestión deportiva del Municipio de Santurtzi, para ello, se emplea un cuestionario específico en el que l obtenemos datos concretos y reales sobre las variables económicas, sociales, técnicas y de Recursos Humanos. Con los datos y resultados de las variables se consigue que al final del estudio se llegue a conclusiones que permitan la autoevaluación en el transcurso del tiempo y la valoración comparada, con municipios de similares características.
