  2. 1. Environmental assessment of bottom ash pre-treated with zero valent iron

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

    Abstract : Bottom ash has similar properties as crushed rocks and gravel, andcould replace some of the 40 million tonnesof virgin material used for road constructions each year.However, results presented in the literature indicate thatthe leaching of e.g. Cr, Cu, Mo, Pb and Zn can cause athreat to the sur rounding environment if the materialis used as it is.

  4. 2. Fluxes and Mixing Processes in the Marine Atmospheric Boundary Layer

    Author : Erik Olof Nilsson; Anna Rutgersson; Harm Jonker; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Waves; Growing sea; Swell; Marine boundary layer; Air-sea interaction; Mixing; Momentum flux; Wind stress; Flux attenuation; Sensor separation; Large eddy simulation; Multiresolution analysis; Coupling; Wave model; Climate model; Wave age; Meteorology; Meteorologi;

    Abstract : Atmospheric models are strongly dependent on the turbulent exchange of momentum, sensible heat and moisture (latent heat) at the surface. Oceans cover about 70% of the Earth’s surface and understanding the processes that control air-sea exchange is of great importance in order to predict weather and climate. READ MORE

  5. 3. Impact of Digitalisation on Environmental Sustainability in Manufacturing Systems

    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; digitalisation; environmental impact; Industry 4.0; manufacturing; sustainability;

    Abstract : Manufacturing companies are striving to improve productivity and reduce the environmental impacts of their activities. Meanwhile, digitalisation plays an important role in increasing productivity and has a profound impact on the environment of manufacturing systems. READ MORE

  6. 4. Research and reflections on European air pollution policy support models

    Author : Stefan Åström; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; Economic perspectives; Decomposition analysis; Policy support modelling; Short-lived Climate Pollutants; Climate metrics; Air pollution; International shipping; Economic methodology; Integrated assessment modelling; Cost-benefit analysis;

    Abstract : European emissions to air of SO2, NOx, PM2.5, NH3 and NMVOC still today cause harm to human health and the environment. These pollutants are associated with the premature death of ~400 000 people annually in the EU (25 000 perished in traffic accidents 2017). Improvements are expected but problems will persist.

  7. 5. Remediation of mercury contaminated soil and biological mercury methylation in the landscape

    Author : Jingying Xu; Stefan Bertilsson; Andrea Garcia Bravo; Dario Acha; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mercury contamination; Soil remediation; Methylmercury; Mercury methylation; hgcA; Community composition; Bacteria; Landscape; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : Accumulation of mercury (Hg) in soil originating from both natural and anthropogenic sources poses a major hazard to environmental and human health. Inorganic Hg(II) in soil can be transformed to highly toxic methylmercury (MeHg) mainly via methylating microorganisms. READ MORE
