“…The decreased levels of certain metals observed at 700 C in relation to lower temperatures indicate partial defractionation and/or their partial volatility at elevated temperatures [12]. Decrease in the content of Cd is a typical phenomenon, observed also by other authors [25]. To better understand, observed changes the atomic ratios of heavy metals to Ca (which does not volatilize) were calculated [26].…”

“…The treated bio-oil showed a higher content of aliphatic and aromatic hydrocarbons compared to the bio-oil produced by pyrolysis only. Nitrogenous species were removed in the form of gaseous ammonia and in the biochar [45][46][47]. Still from Table 3, a notable range of yield fluctuations in bio-oil, biochar, and gas outputs is evident, contingent upon the distinctions of pyrolysis conditions, particularly temperature and reactor design.…”

With the increase in the world population and economic activity, the production of sewage sludge has grown, and its management has become an environmental problem. The most traditional method of managing sewage sludge is to dispose of it in landfills and on farmland. One way to valorize sewage sludge is to use thermochemical conversion processes to produce added-value products such as biochar, biofuels, and renewable gases. However, due to the high moisture content, thermochemical conversion using processes such as pyrolysis and traditional gasification involves multiple pre-treatment processes such as material drying. Hydrothermal thermochemical processes usually require high pressures, which pose many challenges to their application on a large scale. In this work, the advantages and disadvantages of the different existing thermochemical processes for the recovery of sewage sludge were analyzed, as well as the resulting industrial and environmental challenges. A SWOT analysis was carried out to assess the different thermochemical processes in terms of technical feasibility, economic viability, and broader market considerations.

“…Dicha disminución en el contenido del Cd es un fenómeno típico, también observado por otros autores (Beckers et al, 1999;Freddo et al, 2012). Los residuos orgánicos (por ejemplo, los lodos de depuradora) se sabe que generalmente contienen altas concentraciones de metales, que permanecen en el biochar final producto de la pirolisis (Chan y Xu, 2009y Hospido et al, 2005.…”

No sé porqué los agradecimientos es una de las cosas, sino la última, que se escriben cuando se realiza un trabajo de este tipo. Los agradecimientos deberían constituir una parte más del trabajo, ya que sin el apoyo de la gente que tienes alrededor las cosas nunca saldrían… y eso, sin duda, es importante hacerlo público. Y todavía merece aún más la pena destacar este apoyo de la gente de tu entorno cuando, por desgracia, no se tiene la "suerte" de poder contar con una ayuda o financiación para la realización de la tesis, que, de una forma u otra, haría que este duro trabajo pudiera ser más llevadero. Por ello, sin duda alguna, la clave para que esta Tesis haya llegado a buen puerto ha sido la vocación científica que siempre he tenido y seguiré teniendo y la ayuda incondicional de toda la gente de mi alrededor que ha hecho que esta vocación no se pierda.En primer lugar, me gustaría agradecerles muchas cosas a mis directores de tesis, la Dra. Ana Mª Méndez Lázaro y el Dr. José Manuel Fernández Arroyo, no sólo por su apoyo técnico/intelectual, sino sobre todo por su dedicación de tiempo, disponibilidad y confianza.
