2. 1. The Karma of Products : Exploring the Causality of Environmental Pressure with Causal Loop Diagram and Environmental Footprint

   Author : Rafael Laurenti; Björn Frostell; Andrius Plepys; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Products; Environmental Pressure; Causal Loop Diagram; Environmental Footprint; Industrial Ecology; Industriell ekologi;

   Abstract : Environmental pressures from consumer products and mechanisms of predetermination were examined in this thesis using causal loop diagram (CLD) and life cycle assessment (LCA) footprinting to respectively illustrate and provide some indicators about these mechanisms. Theoretical arguments and their practical implications were subjected to qualitative and quantitative analysis, using secondary and primary data. READ MORE

4. 2. Assessing reactive nitrogen flows in European agricultural systems

   Author : Rasmus Einarsson; Chalmers tekniska högskola; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; food; nitrogen indicator; nitrogen budget; nitrogen; agriculture; nitrogen footprint; uncertainties;

   Abstract : In most ecosystems, nitrogen is a scarce and growth-limiting nutrient. Natural and anthropogenic processes convert unreactive atmospheric dinitrogen (N2) into reactive, bioavailable, nitrogen. READ MORE

5. 3. Uncertainty in environmental decision-making : effects of defined or undefined guidance in the decision process

   Author : Karin Luthbom; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

   Abstract : Decision-making in environmental issues often includes uncertainty in the input data and the resulting uncertainty when the data is used. Some spatial decisions are however taken without any formal analysis, meaning that the decision-makers have a mental map and preconceived notions about the decision options before the final decision actually is taken.

6. 4. Excessive Seas : Waste Ecologies of Eutrophication

   Keywords : HUMANIORA; HUMANITIES; algal bloom; Baltic Sea; cultural eutrophication; dead zone; waste ecology; environmental degradation; environmental humanities; critical ocean studies; environmental imaginary; environmental value; more-than- human; textual analysis; visual analysis; storytelling; algblomning; Östersjön; kulturell övergödning; bottendöd; avfallsekologi; miljöförstöring; miljövetenskap; kritiska havsstudier; miljömyndighet; miljövärde; mer-än-mänsklig; textanalys; visuell analys; berättande; Historiska studier av teknik; vetenskap och miljö; History of Science; Technology and Environment;

   Abstract : This dissertation researches how perspectives in western industrial societies communicate about and give meaning to environmental degradation through case studies on the causes and effects of cultural eutrophication—namely nutrient pollution, algal blooms, and dead zones—in the Baltic Sea. Utilizing this approach, this dissertation addresses the ecological problems of cultural eutrophication in marine ecosystems by exposing normative claims humans make about the Baltic Sea and its contents as well as detailing how seas that exceed human expectations may offer insights into negotiating differing perspectives, discrepancies in power, and ways of being among humans and non-humans in marine environments.

7. 5. Industrial Ecology Approaches to Improve Metal Management : Three Modeling Experiments

   Author : Rajib Sinha; Björn Frostell; Maria Malmström; Amir Rashid; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system dynamics; element flow analysis; industrial ecology; product systems; end-of-life; DPSIR; pressure-based driver-oriented approach; environmental management; Industrial Ecology; Industriell ekologi;

   Abstract : A linear model of consumption − produce-use-dispose − has constantly increased the pressure on the environment in recent decades. There has been a great belief that technology will solve the problem, but in many cases it is only partly contributing to the solution. For a full solution, the root causes of problems need to be identified. READ MORE
