Modular Product Architecture’S Decisions Support For Remanufacturing-Product Service System Synergy, Johnson Adebayo Fadeyi
Modular Product Architecture’S Decisions Support For Remanufacturing-Product Service System Synergy, Johnson Adebayo Fadeyi
Wayne State University Dissertations
Remanufacturing is identified as the most viable product end-of-life (EOL) management strategy. However, about 80% of manufactured products currently end up as wastes. Besides other benefits, the product service system (PSS) could curtail the main bottlenecks to remanufacturing namely quantity, quality, recovery time of used product, and negative perception of remanufactured products. Therefore, the integration of PSS and remanufacturing has been increasingly recommended as an enhanced product offering. However, an integration that is informed by mathematical analysis is missing. Meanwhile, the variables that bolster the performance of PSS and remanufacturing are substantially influenced by product development (PD) decisions. Among the …
Integrated Strategies For Sustainable Wastewater-Based Algal Biofuel Production And Environmental Mitigation In The Us, Javad Roostaei
Integrated Strategies For Sustainable Wastewater-Based Algal Biofuel Production And Environmental Mitigation In The Us, Javad Roostaei
Wayne State University Dissertations
Integration of algae cultivation with wastewater treatment has received increasing interest as a cost-effective strategy for biofuel production. However, there has been no full assessment of algal biofuel production with wastewater on macro-scale by taking into account wastewater resources, land availability, CO2 emission resources, and geographic variation. This research addressed and evaluated the use of wastewater for algae cultivation, in terms of modeling and laboratory experiments. The first goal of this research was to develop a spatially explicit lifecycle model, by integrating life cycle assessment (LCA), and Geographic Information Systems (GIS) analysis, for the evaluation of the environmental and economic …

Maximum Recovery Of Mechanical Energy Through Work Integration: A Work Exchange Network Synthesis Approach, Aida Amini Rankouhi
Wayne State University Dissertations
Sustainable development has become a key concern in industries, largely due to natural resource depletion, global competition, and environmental pressure. Despite the efforts for sustainability improvement, still over a half of energy consumption is wasted in manufacturing sectors, where the chemical industry is responsible for an energy efficiency lower than it should be. Many attempts have been made to recover the thermal energy using heat integration techniques. Although process work is more expensive than process heat, no efficient solution has been studied to recover mechanical energy yet. In chemical plants, many process streams need to be pressurized or depressurized in …
Multiscale Design And Life-Cycle Based Sustainability Assessment Of Polymer Nanocomposite Coatings, Rohan Ganesh Uttarwar
Multiscale Design And Life-Cycle Based Sustainability Assessment Of Polymer Nanocomposite Coatings, Rohan Ganesh Uttarwar
Wayne State University Dissertations
In recent years, nanocoatings with exceptionally improved and new performance properties have found numerous applications in the automotive, aerospace, ship-making, chemical, electronics, steel, construction, and many other industries. Especially the formulations providing multiple functionalities to cured paint films are believed to dominate the coatings market in the near future. It has shifted the focus of research towards building sustainable coating recipes which can deliver multiple functionalities through applied films. The challenge to this exciting area of research arrives from the insufficient knowledge about structure-property correlations of nanocoating materials and their design complexity. Experimental efforts have been successful in developing certain …
