Determinación de la energía contenida y emisiones de C02 en el proceso de fabricación del cemento

Abstract

The cement industry is an important sector of CO2 emissions in the world, due to the consumption of large quantities of raw material and energy used during its production process. Cement is an essential material in the construction sector, and knowing the environmental impact caused by its manufacturing in Ecuador is key for obtaining local data. This research has allowed to determine the embodied energy and CO2 emissions in the cement manufacturing process, through the implementation of life cycle assessment methodologies and the 2006 Intergovernmental Panel on Climate Change Guidelines for National Greenhouse Gas Inventories. The study considers the production of 1 ton of cement under a door to door approach, by collecting data from a cement plant corresponding to 1 year of production (2016). The results show that its production requires 3.191,64 MJ of energy and generates 510,54 Kg of CO2 emissions. The highest energy consumption and emissions released into the atmosphere during production were recorded during the clinker manufacturing process, attributing 92.73% of emissions in the system.
