Determinación De La Huella De Carbono Del Banco De Alimentos De Bogotá, María Camila Pantano Escobar
Determinación De La Huella De Carbono Del Banco De Alimentos De Bogotá, María Camila Pantano Escobar
Ingeniería Ambiental y Sanitaria
El Banco de Alimentos de Bogotá es una organización sin ánimo de lucro, que se dedica a la recolección de alimentos y no alimentos y a la distribución de estos a diferentes organizaciones sociales. Debido a sus actividades y al alto flujo de personas que maneja, esta organización se constituye como un generador de gases de efecto invernadero, por esto, en el presente proyecto se realizó la cuantificación de la Huella de Carbono bajo los lineamientos propuestos por el Green House Gas Protocol. De lo anterior, se obtuvieron unas emisiones totales correspondientes al año 2019 de 1527,01 TonCO2, en donde …
Estimación De La Huella De Carbono Por Medio De Software Simapro Para Cultivos De Plantas Ornamentales En La Empresa Colviveros Con Base En Los Lineamientos De La Norma Iso 14044, Mateo Andres Duque Moya, Daniel Felipe Fúquene Linares
Estimación De La Huella De Carbono Por Medio De Software Simapro Para Cultivos De Plantas Ornamentales En La Empresa Colviveros Con Base En Los Lineamientos De La Norma Iso 14044, Mateo Andres Duque Moya, Daniel Felipe Fúquene Linares
Ingeniería Ambiental y Sanitaria
La contaminación atmosférica ha sido uno de los principales problemas a nivel mundial y diferentes puntos de emisión como fábricas, cultivos y otros procesos, de los cuales no se han realizado análisis de ciclo de vida para conocer cuál es su contribución a la huella de carbono. El propósito de este proyecto ha sido determinar la huella de carbono para los principales cultivos de plantas ornamentales comercializadas en la Sabana de Bogotá (Bonsái, pino de vela, eugenias, durantas, ocobos y el saman) con el objeto de realizar recomendaciones para la disminución de los posibles impactos ambientales en su producción. Como …
Life Cycle Assessment (Lca) Of Ore Transportation Route Alternatives For Eagle Mine, Soumith Kumar Oduru
Life Cycle Assessment (Lca) Of Ore Transportation Route Alternatives For Eagle Mine, Soumith Kumar Oduru
Dissertations, Master's Theses and Master's Reports
Transportation sector at large is a major consumer of fossil fuels and constitutes more than a quarter of the global greenhouse gas emissions. When making infrastructure route and mode choice decisions for new freight-oriented projects, it is important that environmental and emissions considerations are included as an integral part of the selection process. Emissions from freight transportation projects related to mining and natural resource industry are especially critical, as they involve high volumes and tonnages often in pristine environments. The most logical time for emissions analysis is during modal and route analysis that are often conducted in the planning stage …
Field Emissions Of (Hydro)Chlorofluorocarbons And Methane From A California Landfill, Alexander H. Sohn
Field Emissions Of (Hydro)Chlorofluorocarbons And Methane From A California Landfill, Alexander H. Sohn
Master's Theses
A comprehensive field investigation was conducted at Potrero Hills Landfill (PHL) located in Suisun City, California to quantify emissions of twelve (hydro)chlorofluorocarbons (i.e. F-gases). The specific target constituents for this study included CFC-11, CFC-12, CFC-113, CFC-114, HCFC-21, HCFC-22, HCFC-141b, HCFC-142b, HCFC-151a, HFC-134a, HFC-152a, and HFC-245fa. The majority of the F-gas emission studies have been conducted outside of the United States and very limited field landfill emission data are available in the United States. Because of historical usage of blowing agents in insulation foams including CFC-11, HCFC-142b, HFC-134a, and HFC-245fa, models reported in literature predicted high F-gas emissions from a landfill …
Evaluation Of The Engine Exhaust Particle Sizer (Eeps) For Real-Time Measurements Of Diesel And Biodiesel Exhaust Particulate Matter, James Robert Dunshee
Evaluation Of The Engine Exhaust Particle Sizer (Eeps) For Real-Time Measurements Of Diesel And Biodiesel Exhaust Particulate Matter, James Robert Dunshee
Graduate College Dissertations and Theses
Even at low concentrations, the criteria air pollutant particulate matter (PM) is an environmental and public health hazard. Emissions levels legislated for modern diesel vehicles are so low (~90% lower than 2003) that it has become difficult to accurately measure PM by the regulatory metric: the mass of particles collected on a filter (i.e., the gravimetric method). Additionally, gravimetric analysis cannot measure real-time emission rates, and therefore is unable to characterize high-emitting transient events (e.g., engine starts, stop-and-go driving). By an alternate method, PM can be estimated by measuring the number-weighted particle size distribution (PSD) and calculating mass with a …
Scenario Generation And Climate Change Modelling Of Nitrous Oxide Emissions From Grasslands In Ireland, Mark Cochrane
Scenario Generation And Climate Change Modelling Of Nitrous Oxide Emissions From Grasslands In Ireland, Mark Cochrane
Theses
Described as a two-year study in relation to nitrous oxide emissions from agricultural grassland in the Republic of Ireland under a set or climate and environmental policy scenarios. Nitrous oxide is a greenhouse gas, with a global warning potential approximately three hundred times that or carbon dioxide. lt is required under the Kyoto Protocol that national inventories or all greenhouse gas emissions are established. The Intergovernmental Panel on Climate Change (IPCC) Tier approach is designed to establish current inventories of greenhouse gas emissions; however a scenario approach is also employed in order to estimate emissions in future years. Scenario sets …
Reviewing The Effects Of Alternative Fuels, Average Speed And Idling Time On Emissions From Orange County School Bus Fleet, Ali Bayat
Electronic Theses and Dissertations
Orange County, FL has been experiencing ozone concentrations in the past several years which in some cases exceeded the national and state standards. The high concentration of ground level ozone can cause a variety of health problems including chest pain, coughing, throat irritation, and congestion or it can worsen bronchitis, emphysema, and asthma. Other effects include reduction of agricultural crop and commercial forest yields, lower growth and survivability of tree seedlings, and higher susceptibility of plant to diseases, pests and other stresses such as harsh weather. The ozone generation rate is directly related to the ambient concentration of nitrogen oxides …
Air Quality Impact Evaluation Of A Hypothetical Fire-Fighter Training Facility, William Glenn Fuller
Air Quality Impact Evaluation Of A Hypothetical Fire-Fighter Training Facility, William Glenn Fuller
Doctoral Dissertations
Human Health Risk Assessments (HHRAs) have become a required component in the permitting process for hazardous waste incinerators and boilers and for closure or evaluation of chemical and petroleum facilities. However, although not currently required, these evaluations are also essential for additional daily processes having the potential to adversely impact the environment. One such process includes emissions produced from a firefighter training facility. Firefighter training facilities perform scenarios to enhance the firefighting ability of the trainees. Three typical scenarios conducted at such a facility include air rescue and firefighting, building fire simulation, and propane system fires. During the course of …
