  1. 31. Factors influencing actors at the interface between the socio-technical and the ecological systems: The case of on-site sewage systems and eutrophication

    Författare :Are Wallin; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; social dilemma; Eutrophication; regulatory compliance; goal-framing theory; on-site sewage systems; homeowners;

    Sammanfattning : Eutrophication, caused by nutrient loading, is a global environmental problem, particularly severe for the Baltic Sea. Long-term solutions rely on the ability of society to respond effectively. This involves, for example, instigating actors who have the capability to directly influence nutrient loads to take action.

  3. 32. Chemistry and Process Design of Integrated Removal of Nitrogen and Sulfur oxides in Pressurized Flue Gas Systems

    Författare :Sima Ajdari; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Carbon capture and storage is vital to reach the climate goals to limit the increase in the global temperature. Among the carbon capture technologies, oxy-fuel and chemical looping combustion produce a stream mainly containing carbon dioxide (CO2) and water but also contaminants such as nitrogen oxides (NOx) and sulfur oxides (SOx).

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

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

    Sammanfattning : 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. LÄS MER

  5. 34. Significance of transport dynamics on concentration statistics and expected mass fraction based risk assessment in the subsurface

    Författare :Veljko Srzic; Vladimir Cvetkovic; Olaf A. Cirpka; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Local scale dispersion; Heterogeneity structure; Concentration moments; Moment collapse; Expected mass fraction;

    Sammanfattning : This thesis relies on a Langrangian framework used for conservative tracer transport simulations through 2-D heterogeneous porous media. Conducted numerical simulations enable large sets of concentration values in both spatial and temporal domains. LÄS MER

  7. 35. On Sustainability of Biomass for Energy and the Governance Thereof

    Författare :Oskar Englund; Virginia Dale; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; sustainability; land use; spatial modelling; biomass production; certification; environmental legislation; biomass resources; ecosystem services; Bioenergy; GIS; biodiversity; governance;

    Sammanfattning : Due to concerns about climate change, energy security, and resource scarcity, non- renewable resources are increasingly being displaced by biomass. As with most human activities, the production of biobased products can be associated with negative impacts. Primarily, this relates to the biomass supply systems, i.e. LÄS MER
