2. 1. Requirement and Availability of Scarce Metals for Fuel-Cell and Battery Electric Vehicles

   Author : Ingrid Råde; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal requirement; sustainability; fuel cells; batteries; platinum; metal scarcity; resources; electric vehicles; metal availability; industrial ecology;

   Abstract : Battery and fuel-cell electric vehicles (EVs) are considered as a means to meet some of the environmental and resource challenges of todays road vehicle system. EVs have the potential for zero tailpipe emissions as well as an energy efficiency higher than internal combustion engine vehicles and they can be flexible concerning primary energy source.

4. 2. Towards recycling of scarce metals from complex products

   Author : Magnus Andersson; Chalmers tekniska högskola; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material flow analysis; Recycling; waste electrical and electronic equipment; scarce metal; end-of-life vehicle; WEEE; ELV; technological innovation system;

   Abstract : Cars and electronic equipment have come to depend on materially complex designs and are drawing attention to issues around sustainable materials management. The dependence of these products and other applications on metals that can be considered scarce, has been brought into political and scientific focus. READ MORE

5. 3. Microbial Treatment of Heavy Metal Leachates

   Author : Teresa Alvarez Aliaga; Bioteknik; []

   Abstract : Ore-mining, metallurgy and other industrial activities represent the source of heavy metal and radionuclide contamination in terrestrial and aquatic environments. Physico-chemical processes are employed for heavy metal removal from industrial wastewater. READ MORE

6. 4. Structuring empirical knowledge on environmental issues : urban heavy metal metabolism

   Author : Johan Hedbrant; Ulrik Lohm; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Föroreningsfrågor; metodik; tungmetaller; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Abstract : During the last century, there has been a large import of heavy metals to urban areas. Only a small fraction, about 10%, has reached the biosphere, the rest is still residing in various goods such as cables, construction materials, technical equipment and batteries, which are still in use or abandoned in infrastructure, buildings, households, enterprises and vehicles.

7. 5. The Specter of Scarcity : Experiencing and Coping with Metal Shortages, 1870-2015

   Author : Hanna Vikström; Per Högselius; Dag Avango; Fjaestad Maja; Ingulstad Mats; KTH; []
   Keywords : HUMANIORA; HUMANITIES; scarcity; critical metals; Sweden; small countries; strategic metals; metal shortages; history of technology; experiences of scarcity; coping with shortages; technological trends; World War I; resource crisis; construction of resources.; Historiska studier av teknik; vetenskap och miljö; History of Science; Technology and Environment;

   Abstract : In spite of an ever-growing supply of metals, actors have long feared metal shortages. This thesis – departing from an understanding that metals scarcity is not an objective geological fact, but an experience, a fear of a shortage – explores why business and state actors have experienced metals as scarce and how they coped with scarcity from 1870 to 2015.
