Producción local de perfiles de aluminio y su impacto en la construcción de viviendas

Dentro de los acabados de viviendas, los materiales más empleados son los perfiles de aluminio que en la localidad se dedica a la comercialización de este insumo que en general son importados. Por ello, la presente investigación tiene como objetivo analizar el impacto que tendría la sustitución de las importaciones por producción local de perfiles de aluminio en los costos y el desempeño en general de la industria de la construcción en la provincia. Para ello se empleó la metodología de evaluación de impacto de la Unión Europea 2006 compuesta por ocho pasos, además se utilizó un enfoque cuantitativo de carácter no experimental, que permitió evaluar el efecto económico de forma objetiva mediante la aplicación de técnicas como encuestas y entrevistas, las mismas que al ser analizadas permitieron sostener la hipótesis siguiente: la producción local de perfiles de aluminio reduce significativamente los costos de construcción de una vivienda. Palabras clave: Productividad; extrusión; importaciones; inversión; efecto económico. ABSTRACT Within the finishes of housing, the most used material are the aluminium profiles themselves that in the locality is dedicated to the commercialization of this input that are usually imported. Therefore, this investigation aims to analyze the impact of replacing imports with local production of aluminium profiles on the costs and overall performance of the construction industry in the province. To this end, the European Union’s eight-step impact assessment methodology was used, and a non-experimental quantitative approach was also used, since it allowed the economic effect to be assessed objectively through the application of techniques such as surveys and interviews themselves that when analyzed made it possible to sustain the hypothesis following: local production of aluminium profiles significantly reduces the costs of building a home. Keywords: Productivity; extrusion; imports; investment; economic effect.

Abstract Radioactive wastes often contain considerable amounts of non-radiological and potentially toxic components such as heavy metals, organics, etc. The present study discusses an impact assessment methodology applied to the surface repository located at Olen (Belgium) containing various wastes from radium and uranium production. The impact assessment considered leaching to groundwater and use of groundwater for production of drinking water and irrigation. Leaching of radionuclides and non-radiological components from the storage facility was calculated using numerical models of water flow and contaminant transport. Results showed that leaching from the waste forms containing the highest concentration in radium, uranium, lead, and arsenic (i.e., various uranium mill tailings and radium sources and needles) did not lead to unacceptable concentrations in the groundwater when a reasonable leaching period was considered.
