Sustainable Valorisation of Biowaste for Soilless Cultivation of Salvia Officinalis in a Circular Bioeconomy
2020
The aim of this work is to assess the usefulness of biowaste deriving from CircularBioeconomy (CBE) processes (i.e., vermicompost, compost and digestate), as growing substratesfor the partial or total replacement of peat, by measuring the vegetation biometric parameters ofsage (Salvia officinalis L.)&mdash
Risk of Invasive Lupinus polyphyllus Seed Survival in Biomass Treatment Processes
2021
Invasive plant species threaten native species and habitats causing ecologic, economic and social burden. When creating climate friendly solutions by utilizing plant biomasses in biogas and fertilizer production, safety should be ensured concerning the use of residues. This study concentrates on the treatment of biomasses containing invasive plant material by tunnel and windrow composting, and by farm-scale and laboratory-scale anaerobic digestion (AD) in mesophilic conditions. Germination of the nationally settled and harmful invasive species Lupinus polyphyllus Lindl. was investigated after these processes. In addition, the role of the conditions found in the processes that destroyed seed…
Ultrathin films of layered coordination polymers: charge transport and spin crossover at the nanoscale
2019
La present tesi doctoral ha estat realitzada com a compendi de publicacions i porta per títol "Pel·lícules ultrafines de polímers de coordinació en capes: transport de càrrega i transició d'espín en la nanoescala" (Ultrathin films of layered coordination polymers: charge transport and spin-crossover at the nanoscale). Aquesta es divideix en quatre capítols a més d'un capítol final de conclusions i resums en castellà i valencià. El primer capítol consisteix d'una introducció general enfocada cap a donar una visió general del transport de càrrega en xarxes metall-orgàniques (de l'anglès metal-organic frameworks, MOFs) i polímers de coordinació (de l'anglès coordination polymers, CPs), així co…
Estudio del compostaje como técnica para la eliminación de contaminantes emergentes
2017
Desde hace unos años está surgiendo una nueva clase de contaminantes químicos utilizados por el hombre con distintas finalidades y denominados contaminantes emergentes, entre los cuales se incluyen los productos farmacéuticos. Todos estos compuestos se encuentran en las aguas residuales, y como las estaciones de depuración de aguas residuales no están acondicionadas para eliminarlos, acaban liberándose en el medio ambiente. La mayor acumulación de estos compuestos se produce en los lodos que son utilizados en agricultura y compostaje. De hecho, se han encontrado fármacos de uso humano y fungicidas de aplicación agrícola en aguas superficiales, suelos, biosólidos e incluso en agua potable. E…
Biological nitrogen removal from landfill leachate: a pilot-scale study
1999
A pilot-scale two-stage process including an anaerobic pretreatment (up-flow anaerobic sludge blanket, UASB) unit and a pre-denitrification activated sludge process was studied for treating leachates from a municipal landfill (waste aged 4 to 5 years, area 2.5 ha) and from a windrow composting area (1ha). A single-stage pilot process was used for nitrification studies. The leachate characteristics were as follows: COD 740 to 2400 mg 1-1 (chemical oxygen demand), BOD7 (biochemical oxygen demand) approximately 1000 mg 1 -1, Ntot 40 to 120 mg 1-1 and the temperature was between 2 and 21°C. The results show that 45 to 50% COD removal could be achieved in the UASB reactor even at temperatures b…

The Role of Covalent Functionalization in the Thermal Stability and Decomposition of Hybrid Layered Hydroxides
2020
The room temperature synthesis of two Co-based hybrid layered hydroxides containing the same organic ligand (suberate [Sub]), one connected through purely electrostatic interactions (CoAl layered double hydroxide [LDH]), and the other covalently functionalized (α-CoII simonkolleite phase) has been carried out. The magnetic properties exhibit an acute difference in the magnetization temperatures (from ≈10 K for the CoAl-LDH to ≈55 K for the α-CoII). Moreover, the role of the covalent functionalization in the thermal stability and the decomposition has been investigated by a forefront characterization tool consisting of thermogravimetric analysis coupled with gas chromatography and mass spect…
