espanolEl proceso experimental fue propuesto a fin de establecer la viabilidad de sustituir parte de la fraccion mineral usada en la actualidad (material arcilloso) por residuos de procesos de combustion (cenizas) de carbon mineral en termoelectrica, como elemento para reducir la huella de carbono del proceso de produccion de productos ceramicos, sin alterar la calidad, propiedades y funcionalidad del producto final. El estudio se centra en el caso concreto de una empresa ladrillera del area metropolitana de Cucuta, y en la sustitucion de un 10% de la materia prima (arcilla) por cenizas procedentes de la central termoelectrica, para la produccion de bloque ceramico. Los analisis realizados establecen un ahorro energetico derivado del uso de un 10% de ceniza volante equivalente a 997.12Kg de carbon de Norte de Santander por quema. Los resultados determinan que, para el caso de la produccion de la ladrillera, la reduccion anual de emisiones asociadas al proceso productivo, con el uso de cenizas de la termoelectrica, seria de 849.48 toneladas de CO2. Asi, la huella de carbono se ve reducida en 16.39kgCO2equiv/t producto acabado, lo que supone un descenso de un 5,99% de la huella de carbono respecto del proceso convencional. EnglishThe experimental process was proposed in order to establish the viability of substituting part of the mineral fraction used at present (clayey material) by residues of combustion processes (ashes) of coal in thermoelectric, as an element to reduce the carbon footprint of the process of production of ceramic products, without altering the quality, properties and functionality of the final product. The study focuses on the specific case of a brick-making company in the metropolitan area of Cucuta, and on the substitution of 10% of the raw material (clay) for ashes from the thermoelectric plant, for the production of ceramic blocks. The analyses carried out establish an energy saving derived from the use of 10% fly ash equivalent to 997.12Kg of Norte de Santander coal per burn. The results determine that, in the case of brick production, the annual reduction of emissions associated with the production process, with the use of ashes from the thermoelectric, would be 849.48 tons of CO2. Thus, the carbon footprint is reduced by 16.39kgCO2equiv/t finished product, which represents a decrease of 5.99% of the carbon footprint compared to the conventional process.
