Assessment of abiotic and biotic resource use for products and regions in the context of sustainable development

Bach, Vanessa (2018)

Resources are the basis for a thriving industrial and technological development and therefore for prosperity of present and future generations. With increasing resource use, challenges with regard to (physical and socio-economic) availability of abiotic and biotic resources and raw materials, pollution of the environment as well as social impacts associated with resource extraction and use aris...

Optimierung der passiven Dialyse zur Inline-Probenvorbereitung in der Ionenchromatographie

Markeviciute, Inga (2018)

The focus of this Ph.D. Thesis is the instrumental improvement and optimization of a commercially available system for stopped-flow dialysis in hyphenation with ion chromatography. The two main aspects of the present thesis are the application of dialysis membranes permitting better separation of potentially interfering compounds and shortening of the dialysis time required to achieve concentra...

Application options of the Sustainable Child Development Index (SCDI) – assessing the status of sustainable development and establishing social impact pathways

Chang, Ya-Ju ; Lehmann, Annekatrin ; Winter, Lisa ; Finkbeiner, Matthias (2018-07-02)

The needs of children and their vulnerability to diseases, violence and poverty are different from those of adults. The Sustainable Child Development Index (SCDI) was thus developed in previous work to evaluate the status of sustainable development for countries with a focus on children and triple-bottom-line thinking. This study proposes application options to put the SCDI into practice. The S...

Optimierung der normgerechten Intensitätsbewertung und Untersuchung weiterer Referenzgerüche zur Qualitätssicherung

Brosig, Laura (2018)

For energy saving purposes buildings are constructed increasingly airtight. Due to insufficient ventilation emissions from building materials and products might accumulate indoors. Not only emissions of volatile organic compounds (VOC) may cause impact on health and well-being of occupants but odours as well. Therefore, their perceived intensity can be assessed based on acetone as reference sub...

The purpose of this paper is to provide information obtained through the International Workshop in Kyoto, Japan, on 11–13 November 2015, which included invited experts and researchers in several countries who were in charge of 3R policies, and ...

The WULCA consensus characterization model for water scarcity footprints: assessing impacts of water consumption based on available water remaining (AWARE)

Boulay, Anne-Marie ; Bare, Jane ; Benini, Lorenzo ; Berger, Markus ; Lathuillière, Michael J. ; Manzardo, Alessandro ; Margni, Manuele ; Motoshita, Masaharu ; Núñez, Montserrat ; Pastor, Amandine Valerie ; Ridoutt, Bradley ; Oki, Taikan ; Worbe, Sebastien ; Pfister, Stephan (2017-06-08)

Purpose Life cycle assessment (LCA) has been used to assess freshwater-related impacts according to a new water footprint framework formalized in the ISO 14046 standard. To date, no consensus-based approach exists for applying this standard and results are not always comparable when different scarcity or stress indicators are used for characterization of impacts. This paper presents the outcom...

The Sustainable Child Development Index (SCDI) for countries

Chang, Ya-Ju ; Lehmann, Annekatrin ; Winter, Lisa ; Finkbeiner, Matthias (2018-05-14)

Despite the relevance of children in inheriting and shaping society, an index assessing sustainable development with a focus on children is missing. To tackle this gap, this study established the Sustainable Child Development Index (SCDI) by considering child development topics in the context of inter-generational equity and applying indicators with available statistical data on country level. ...

Addressing sustainability and flexibility in manufacturing via smart modular machine tool frames to support sustainable value creation

Peukert, Bernd ; Benecke, Stephan ; Clavell, Janire ; Neugebauer, Sabrina ; Nissen, Nils F. ; Uhlmann, Eckart ; Lang, Klaus-Dieter ; Finkbeiner, Matthias (2015)

Sustainability and flexibility are crucial aspects in todays’ manufacturing processes. Within this study an innovative approach of modular machine tool frames (MMTF) equipped with micro system technology is presented that aims at enhancing flexibility of mutable production processes. This new approach extends the existing reconfigurable manufacturing systems (RMS). MMTF goes beyond the platform...

Sustainable corporate development measured by intangible and tangible resources as well as targeted by safeguard subjects

Orth, Ronald ; Scheumann, René ; Galeitzke, Mila ; Wolf, Kirana ; Kohl, Holger ; Finkbeiner, Matthias (2015)

The needed shift towards sustainable development in existing business processes can be achieved through the combination of the capital based approach and the life cycle sustainability assessment. This contribution performs an analysis and selection of assessment tools and indicators regarding the resources used in organisational processes and the life cycle of the products or services to measur...

Environmental and Social Life Cycle Assessment of welding technologies

Chang, Ya-Ju ; Sproesser, Gunther ; Neugebauer, Sabrina ; Wolf, Kirana ; Scheumann, René ; Pittner, Andreas ; Rethmeier, Michael ; Finkbeiner, Matthias (2015)

Life Cycle Assessment (LCA) and Social Life Cycle Assessment (SLCA) are applied in evaluating possible social and environmental impacts of the state-of-art welding technologies, such as Manual Metal Arc Welding (MMAW), Manual Gas Metal Arc Welding (GMAW), Automatic GMAW and Automatic Laser-Arc Hybrid Welding (LAHW). The LCA results indicate that for 1 meter weld seam, MMAW consumes the largest ...

The role of water level fluctuations in the promotion of phytoplankton and macrophyte pioneer species in a tropical reservoir in the Brazilian semiarid

Lima, Débora Maciel Barros (2018)

In the semiarid northeast Brazil, water paucity instigates multiple uses of reservoirs, such as hydropower production, drinking water supply, water supply for livestock and for irrigation, fisheries, aquaculture and leisure activities. As consequence of high anthropogenic pressure, most reservoirs in this region are fragile and eutrophicated systems. Blooms of algae and macrophytes are commonly...

Microbial population composition of ochrous biofilms and water samples obtained from technical groundwater-fed systems

Schröder, Josephin (2018)

This study assessed the abundance, composition, diversity and functional organisation of bacterial communities correlated to chemical water parameters in four technical groundwater-fed systems. Each sampling site was vulnerable to iron-clogging and was characterised by its own specific technical and hydrochemical conditions. Biofilm and groundwater samples were obtained and compared for drinkin...
