Fecha de publicación: | 2021 | Editor: | Multidisciplinary Digital Publishing Institute | Citación: | ChemEngineering 5 (2): 16 (2021) | Resumen: | In this work, concentrated solar energy (CSE) was applied to an energy-intensive process such as the vitrification of waste with the aim of manufacturing glasses. Different types of waste were used as raw materials: a hazardous waste from the aluminum industry as aluminum source; two residues from the food industry (eggshell and mussel shell) and dolomite ore as calcium source; quartz sand was also employed as glass network former. The use of CSE allowed obtaining glasses in the SiO2-Al2O3-CaO system at exposure time as short as 15 min. The raw materials, their mixtures, and the resulting glasses were characterized by means of X-ray fluorescence, X-ray diffraction, and differential thermal analysis. The feasibility of combining a renewable energy, as solar energy and different waste for the manufacture of glasses, would highly contribute to circular economy and environmental sustainability. | Versión del editor: | httpS://doi.org/10.3390/chemengineering5020016 | URI: | http://hdl.handle.net/10261/251051 | DOI: | 10.3390/chemengineering5020016 | Identificadores: | doi: 10.3390/chemengineering5020016 issn: 2305-7084 |
