  1. 1. Industrial Ecology and Development of Production Systems : Analysis of the CO2  Footprint of Cement

    Författare :Roozbeh Feiz; Mats Eklund; Jonas Ammenberg; Henrikke Baumann; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial ecology; industrial symbiosis; industrial development; life cycle assessment; multi-criteria assessment; CO2 footprint; cement;

    Sammanfattning : This research is an attempt to create a comprehensive assessment framework for identifying and assessing potential improvement options of cement production systems.From an environmental systems analysis perspective, this study provides both an empirical account and a methodological approach for quantifying the CO2 footprint of a cement production system.

  3. 2. Carbon exchange in boreal ecosystems: upscaling and the impacts of natural disturbances

    Författare :Julia Kelly; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Carbon fluxes; CH4; Climate change; CO2; Drought; Ecosystem respiration; Forest; Peatland; Remote sensing; Temperature; Thermal camera; UAV; Wildfire;

    Sammanfattning : Boreal forests and peatlands are globally significant carbon stores but they are threatened by rising air temperatures and changes in precipitation regimes and the frequency of natural disturbances. Predicting how the boreal biome will respond to climate change depends on being able to accurately model and upscale the greenhouse gas fluxes between these ecosystems and the atmosphere. LÄS MER

  4. 3. Supercritical CO2 technology in resource-effectiveproduction of functional and smart textiles

    Författare :Molla Tadesse Abate; Satoko Okubayashi; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supercritical CO2; Polyester; Functional textile; Smart textile; Antimicrobial; Antioxidant; UV protection; Textile UV-sensor; Curcumin; Chitosan; Photochromic materials; Photo-grafting; halochromic textile; Resource Recovery; Resursåtervinning;

    Sammanfattning : The demand for functional and smart textiles has risen nowadays due to the lifestyle change of human beings. Along with this, the production of functional and smart textiles is consistently increasing. LÄS MER

  5. 4. A Negative Footprint Illusion in Environmental Impact Estimates

    Författare :Mattias Holmgren; Patrik Sörqvist; Ola Eriksson; Maria Ojala; Högskolan i Gävle; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; The negative footprint illusion; averaging bias; environmental impact estimates; decision-making; climate change; Den negativa fotavtryckillusionen; genomsnittsprocess; miljöpåverkan; beslutsfattande; klimatförändringarna; inget Strategiskt forskningsområde SFO ; no Strategic Research Area SFO ;

    Sammanfattning : A major part of anthropogenic climate change is due to everyday human behavior, such as transportation, food and energy consumption. As a result, it has been argued that many barriers for mitigating climate change are psychological in nature. LÄS MER

  7. 5. Methodologies for Non-aqueous Systems and Precipitating Systems as Carbon Capture Technologies : A case-study of AMP-NMP

    Författare :Meher Sanku; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; non-aqueous; precipitating; thermodynamic model; crystallization kinetics;

    Sammanfattning : In order to combat the effects of climate change, it is important to use a combination of solutions to achieve carbon neutrality as soon as possible. Carbon capture and sequestration is one such technology that can be used to significantly reduce the carbon footprint of many industrial plants. LÄS MER
