Powering An Industry: The History Of The Calumet And Hecla Electrical System And The Environmental Consequences Left Behind, Emma M. Zawisza Jan 2016

Powering An Industry: The History Of The Calumet And Hecla Electrical System And The Environmental Consequences Left Behind, Emma M. Zawisza

Dissertations, Master's Theses and Master's Reports

The Calumet and Hecla Copper Mining Company in Houghton County, Michigan, was established in 1865 and closed its doors in 1968. This company was a major contributor in developing secondary copper processing and used these methods to produce copper even when its underground mines were closed. C&H built its own electrical transmission system that could have rivaled many during its time. This allowed the company to have the ability to produce and control its electrical network and expand, but it had major environmental effects. Polychlorinated biphenyl compounds (PCBs), used in transformer oil and other components were produced between about 1930 …


Contributions Of Glacier Melting To The Upper Watershed Of The Pita River, Ecuador, Teresa Munoz Martinez Jan 2016

Contributions Of Glacier Melting To The Upper Watershed Of The Pita River, Ecuador, Teresa Munoz Martinez

Dissertations, Master's Theses and Master's Reports

Evidence suggests that a changing global climate is accelerating glacial retreat around the world. However, there are not many studies that help to understand the influence of climate change on glaciers in the tropical Andes. In many Andean countries, populations use the water that come from the high altitude mountains, especially mountains that are ice covered. Glacial reduction minimizes water resource availability. This report focuses on better understanding the relationship between glacier meltwater, surface water runoff, and the groundwater flowing into and under the Pita River upper watershed, which crosses the base of the northeast foothills of the Cotopaxi volcano. …


Energy Justice And U.S. Energy Policy: Case Study Applications Exploring U.S. Energy Policy Through An Energy Justice Framework, Emily Prehoda Jan 2016

Energy Justice And U.S. Energy Policy: Case Study Applications Exploring U.S. Energy Policy Through An Energy Justice Framework, Emily Prehoda

Dissertations, Master's Theses and Master's Reports

This thesis presents three examples of U.S. energy policy and demonstrates how these policies violate the principles of energy justice. First, requiring only Federal agencies to obtain a percentage of energy production from renewables violates the distributive energy justice principle through a lack of a federal renewable energy policy which distributes the potential for unequal electrical grid failure to populations. Second, U.S. energy policy violates the procedural energy justice principle through inequitable participation and poor knowledge dissemination that, in some cases, contributes to stagnant renewable targets during the decision-making process and inequitable distribution of the benefits associated with renewable energy …


Shipbreaking In Bangladesh: Perspectives From Industrial Ecology, Political Ecology And Environmental Policy, S.M. Mizanur Rahman Jan 2016

Shipbreaking In Bangladesh: Perspectives From Industrial Ecology, Political Ecology And Environmental Policy, S.M. Mizanur Rahman

Dissertations, Master's Theses and Master's Reports

The international shipbreaking industry connects developed and developing countries through the spatial and temporal flow of resources, both transported by the ships and by the recycling of the ships themselves. Much of the research on this industry to date focuses on a natural science perspective, particularly related to local pollution when the ships are recycled. However, many products for the public (such as documentaries and magazine articles) focus on the workers who dismantle these ships, often with minimal protection; the appalling images of shipbreaking yard workers and their polluted surrounds have garnered immense global attention and calls for better regulations. …


A Sustainability-Based Project Selection Algorithm: Socio-Technical-Economic Project Selection (Steps) Algorithm, Bharathi Bhattu Jan 2016

A Sustainability-Based Project Selection Algorithm: Socio-Technical-Economic Project Selection (Steps) Algorithm, Bharathi Bhattu

Dissertations, Master's Theses and Master's Reports

Multi-dimensional aspects play a vital role in the task of project-decision making. Environmental effects are to be considered in addition to other technical and non-technical aspects in order to avoid undue environmental damage. This current work introduces a new decision-making algorithm (Socio-Technical-Economic Project Selection or STEPS) that is demonstrated with the use of RCA (recycled concrete aggregate) as riprap for slope stabilization and erosion control which leaches chemical arsenic when in contact with water. Arsenic has long been recognized for its lethal properties. The main intention of introducing this new algorithm is to use sustainability concepts of social, technical, and …
