The objective of this study was to analyze the management and use of organic solid waste through generation rates by type of waste in the sodas of the Campus Omar Dengo of the National University of Costa Rica. The raw and cooked residues were collected in five sodas, weighed and based on this data, daily waste generation rates were calculated. In addition, a survey was conducted in order to determine the perception of users about this problem. It was evidenced that the amount of waste varied significantly during the sampling period and it varies in each soda. Social aspects, as well as quality and proximity, induce greater user assistance; therefore, the generation of waste is increased. It is concluded that it is necessary deeper studies that allow the reduction of waste, as well as the awareness of the users of the sodas.
La cuantificación y medición de la huella hídrica permite analizar y tener un control sobre la gestión ambiental de la institución, además de tomar acciones que integren la totalidad de la población universitaria, orientando todos los esfuerzos hacia un desarrollo sustentable. El objetivo de la investigación es cuantificar y calcular la huella hídrica azul institucional para el periodo 2012-2016, con el fin de analizar y comparar, así, su comportamiento en el tiempo, de acuerdo con las variables contempladas en el cálculo, consumo de agua, consumo de combustible fósil, papel y energía eléctrica (puesto que se consideran fundamentales para el desenvolvimiento y funcionalidad de actividades institucionales). Se aplicó la metodología de Hoekstra y Chapagain, expuesta en el Manual de evaluación de la huella hídrica; con los factores de huella hídrica y agua virtual, tomados de Water Footprint Network, se obtuvo la cantidad correspondiente a cada rubro. Como resultado, entre el 2012 y el 2015, se llegó a una disminución del 8 % de la huella hídrica, pasando de 966 432 m3 a 888 693 m3. Mientras tanto, en el 2016, se alcanzó un leve aumento, dando un valor total de 891 976 m3.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
