Integration Of Techno-Economic Analysis (Tea) And Life Cycle Assessment (Lca) For Sustainable Process Design, Roksana Mahmud Aug 2022

Integration Of Techno-Economic Analysis (Tea) And Life Cycle Assessment (Lca) For Sustainable Process Design, Roksana Mahmud

All Dissertations

For sustainable design, technology developers need to consider not only technical and economic aspects but also potential environmental impacts while developing new technologies. Techno-economic analysis (TEA) evaluates the technical performance and economic feasibility of a technology. Life cycle assessment (LCA) evaluates the potential environmental impacts associated with a product system throughout its life cycle from raw material extraction to disposal. Generally, TEA and LCA are performed separately for technology assessment. Understanding of the trade-off between economic and environmental performances is crucial for sustainable process design, which is not fully available if TEA and LCA is performed separately. In contrast, integration …


Building For The Future: Functional, Energy-Efficient, And Beautiful Buildings By Snøhetta, Amanda J. Oross Apr 2022

Building For The Future: Functional, Energy-Efficient, And Beautiful Buildings By Snøhetta, Amanda J. Oross

Student Publications

The construction industry accounts for nearly 40% of all greenhouse gas emissions, which ultimately leads to climate change. Because of a lack of global consensus and accountability on a large scale about how to combat climate change, certain countries and cities are leading the charge on mitigation, since they tend to be more progressive and homogenous. Norway is one of those countries, and happens to be the headquarters for Snøhetta, a design company, that is designing buildings that are not only energy-efficient but also functional for the space in which it resides. Snøhetta very much values the interconnection between the …


Properties And Environmental Impacts Of Sustainable Electrically Conductive Composites Of Carbonized Pulp Fibers And Recycled Polyamide 12, Chinmoyee Das Jan 2022

Properties And Environmental Impacts Of Sustainable Electrically Conductive Composites Of Carbonized Pulp Fibers And Recycled Polyamide 12, Chinmoyee Das

Dissertations, Master's Theses and Master's Reports

Electrically conductive composites are polymer composites filled with electrically conductive filler. Electrically conductive composites can be implemented in the development of lightweight electrically conductive components for the automotive industry. Traditional electrically conductive composites incorporate synthetic carbon-based fillers that have good properties but are very expensive and highly energy intensive, creating the need for a sustainable and cost-effective replacement. This study explores the effectiveness of biocarbon fibers developed from Douglas fir pulp fibers as a potential electrically conductive filler in recycled polyamide (PA) 12 composites.

Biocarbon fibers were developed from pulp by carbonization of the feedstock at 1000° C in an …
