Show moreWith advancements in healthcare, we continue to find new needs that must be addressed. Hospitals generate a substantial amount of medical waste, and proper disposal is important for patient and staff safety, environmental protection, and cost efficiency. A series of studies show there is a need for further education on hospital waste management policies. This thesis aims to evaluate education interventions to improve knowledge and healthcare waste disposal practices. This literature review was conducted using multiple databases, including MedLINE, CINAHL, GreenFILE, Google Scholar, EBSCOhost, and NCBI, to find qualifying research articles in the English language from 2005-2018. Key terms for the searches were: education, training, waste, disposal, healthcare, medical, reduction, hospital, pound, and kilogram. Results demonstrate that further education on hospital waste management has the potential to reduce waste, improve disposal and segregation, and reduce costs. However, the lack of consistency in the research, literature, and educational interventions all pose as limitations. Hospitals have the potential to benefit from improved waste management practices by enhancing patient care, reducing waste, saving costs on waste disposal, and protecting the environment.

Abstract / Description
Energy and water are consumed or contaminated during both the production and disposal of wasted food. To date, evaluations of water and energy resources associated with food waste have considered only resources used in food production. To allow for the full characterization of food waste within a Food Energy Water (FEW) nexus framework, this study addresses a fundamental knowledge gap related to the energy and water impacts of food waste after disposal.

Show moreEnergy and water are consumed or contaminated during both the production and disposal of wasted food. To date, evaluations of water and energy resources associated with food waste have considered only resources used in food production. To allow for the full characterization of food waste within a Food Energy Water (FEW) nexus framework, this study addresses a fundamental knowledge gap related to the energy and water impacts of food waste after disposal. Fluxes of water and energy related to disposal of wasted food in landfills within the state of Florida were characterized. It is estimated that each metric ton (Mg) of landfilled food waste produces 18.1 kWh of energy, while the energy needed for collection, leachate transport, and treatment totals 126.5 kWh/Mg. These values equate to a net energy cost of 108.4 kWh/Mg, which is 110 Million kWh annually in Florida. It was observed that the water footprint of landfilled food waste is related to the assimilation of contaminated effluent and ranges from 2.5 to 58.5 m3 per metric ton of landfilled food waste, depending on the constituent of interest. Up to 58 Million m3 of water may be required annually to assimilate contamination related to landfilled food waste in Florida. We assessed the sensitivity of 14 variables used to estimate energy and water impacts and found that impacts are sensitive to the proportion of landfills collecting and utilizing landfill gas, concentration of constituents in leachate, and volume of effluent. Future research should be focused to improving the characterization of these influential parameters, and to similar FEW analysis of other food waste management technologies, such as composting or anaerobic digestion. Better understanding of water and energy impacts of food waste could inform societal decision making regarding investment in FEW-efficient waste management technologies.

Show moreThe objective of this research is to identify the need for stricter environmental standards and regulations in three areas of study. Organized by their level of analysis, these areas are Latin America (at the System-Level-of Analysis), Colombia (at the State-Level-of-Analysis), and the city of Cartagena (at the Sub-National-Level of Analysis). This research was accomplished in two phases. The first involved conducting an exhaustive literature search of sources, germane to the objective, published in Spanish and English. The second featured a site inspection conducted over a 10-day period during the month of May 2016 to Cartagena, Colombia. The purpose of the site inspection was to interview locals and to photographically document waste disposal practices. The results of this research determined that government at all levels (system, state, and subnational) play a significant and sometimes determinant role in managing waste and water pollution that are responsible for health problems primarily among the poor; these health problems are discussed in detail. This research discovered that the lack of government intervention is responsible for reducing the efficacy of waste management and water sanitation services. This research concludes with a discussion of how proactive waste management and water sanitation policies and practices can have a significant benefit not only to improving health but also has significant economic, social and environmental benefits that may reach beyond local levels.

Show moreThree troublesome issues concerning residential curbside collection (RCC) and municipal solid waste (MSW) management systems in the United States motivated this research. First, reliance upon inefficient collection and scheduling procedures negatively affect RCC efficiency, greenhouse gas (GHG) emissions, and cost. Second, the neglected impact of MSW management practices on water resources. Third, the implications of alternative fuels on the environmental and financial performance of waste collection where fuel plays a significant rule. The goal of this study was to select the best RCC program, MSW management practice, and collection fuel. For this study, field data were collected for RCC programs across the State of Florida. The garbage and recyclables generation rates were compared based on garbage collection frequency and use of dual-stream (DS) or single-stream (SS) recyclables collection system. The assessment of the collection programs was evaluated based on GHG emissions, while for the first time, the water footprint (WFP) was calculated for the most commonly used MSW management practices namely landfilling, combustion, and recycling. In comparing alternative collection fuels, two multi-criteria decision analysis (MCDA) tools, TOPSIS and SAW, were used to rank fuel alternatives for the waste collection industry with respect to a multi-level environmental and financial decision matrix. The results showed that SS collection systems exhibited more than a two-fold increase in recyclables generation rates, and a ~2.2-fold greater recycling efficiency compared to DS. The GHG emissions associated with the studied collection programs were estimated to be between 36 and 51 kg CO2eq per metric ton of total household waste (garbage and recyclables), depending on the garbage collection frequency, recyclables collection system (DS or SS) and recyclables compaction. When recyclables offsets were considered, the GHG emissions associated with programs using SS were estimated between -760 and -560, compared to between -270 and -210 kg CO2eq per metric ton of total waste for DS programs. In comparing the WFP of MSW management practices, the results showed that the WFP of waste landfilling can be reduced through implementing bioreactor landfilling. The WFP of electricity generated from waste combustion was less than the electricity from landfill gas. Overall, the WFP of electricity from MSW management practices was drastically less than some renewable energy sources. In comparing the WFP offsets of recyclables, the recycling of renewable commodities, e.g. paper, contributed to the highest WFP offsets compared to other commodities, mainly due to its raw material acquisition high WFPs. This suggests that recycling of renewable goods is the best management practice to reduce the WFP of MSW management. Finally, the MCDA of alternative fuel technologies revealed that diesel is still the best option, followed by hydraulic-hybrid waste collection vehicles (WCVs), then landfill gas (LFG) sourced natural gas, fossil natural gas and biodiesel. The elimination of the fueling station criterion from the financial criteria ranked LFG-sourced natural gas as the best option; suggesting that LFG sourced natural gas is the best alternative to fuel WCV when accessible. In conclusion, field data suggest that RCC system design can significantly impact recyclables generation rate and efficiency, and consequently determine environmental and economic impact of collection systems. The WFP concept was suggested as a method to systematically assess the impact of MSW management practices on water resources. A careful consideration of the WFP of MSW management practices and energy recovered from MSW management facilities is essential for the sustainable appropriation of water resources and development.
