The demand from consumers for more sustainable products, and the need to comply with government regulations motivates manufacturers to evaluate their operations for opportunities to reduce environmental impact and improve economic competitiveness. Manufacturers have actively improved the sustainability performance of their products through the use of sustainability assessment methods and...
Existing studies on industrial heat demand have shown that more than 50% of the industrial process heat demand is in the range of low (<60 °C), medium (60-150 °C), and medium-high (<250 °C) temperatures. Most of the manufacturing industries across the world depend on combustion of carbon-based fossil fuels, either...
The research explored in this thesis helps provide a better understanding of efforts that have been undertaken to more precisely calculate environmental impacts and human health risks, such as energy consumption, carbon footprint, and toxicity, to support environmental sustainability assessment of products. The work is comprised of two research objectives,...
Sustainability has become an unprecedented priority in global manufacturing due to the growing concerns over issues such as an aging workforce, environmental degradation, and public health. The simultaneous consideration of the economic, environmental, and social aspects – often referred to as the “three pillars of sustainability” – is crucial to...

Zinc oxide nanoparticles (ZnO NPs) have demonstrated the ability to improve lubrication and thermal conductivity, and stand as promising metalworking lubricant and coolant additives due to their low cost compared to other NPs. While nanomaterials are a focus of research due to their potential to enable advanced technologies, little is...
Specific energy, defined as the energy consumed by per unit volumetric removal rate, is one of the key metrics used for evaluating the environmental performance of a machining process. Grinding is a traditional machining process, characterized by high specific energy and poor environmental performance. Growing global concerns about climate change...
Methane is a flammable gas that is the main component of natural gas. It is a highly potent greenhouse gas, and accounts for about 20% of greenhouse gas emissions. Methane is routinely flared in many industrial processes without harnessing any of its energy. The environmental impact and wasted energy potential...
Many streams in eastern Oregon are listed as water quality impaired on the basis of water temperature. However, it is often difficult to predict water temperature for these streams even if there are no anthropogenic impacts. We measured air and water temperature and stream characteristics on three Type C and...
Sustainability has been the focus of intense discussions over the past two decades, with topics around the entire product life cycle. In the manufacturing phase, research has been focused solely on environmental impact assessment or environmental impact and cost analysis in its assessment of sustainability. However, few efforts have investigated...

Wind energy is a promising alternative energy source due to its environmental, economic, and social benefits and, as such, has garnered public support and government incentives for its development and implementation. With the growing number of wind parks in Oregon, a life cycle assessment (LCA) study for a representative new...
