  2. 1. Systems Analysis for Eco-Industrial Development : Applied on Cement and Biogas Production Systems

    Author : Roozbeh Feiz; Mats Eklund; Jonas Ammenberg; Olli Salmi; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial ecology; eco-industrial development; multi-criteria analysis; life-cycle assessment; MCA; LCA; uncertainty management; systems analysis; industrial symbiosis; cement; biogas; cement production; biogas solutions;

    Abstract : Our industrial systems are not sustainable—a major challenge which demands several types of responses. Eco-industrial development can be seen as such a response, with the goal to establish industrial systems that are both ecological and economical. Industrial Ecology is another closely related response. READ MORE

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

    Author : Roozbeh Feiz; Mats Eklund; Jonas Ammenberg; Henrikke Baumann; Linköpings universitet; []
    Keywords : 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;

    Abstract : 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.

  5. 3. Early Hydration of Portland Cement

    Author : Rikard Ylmén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SEM; freeze-drying; cement; calorimetry; nano-silica; carbonation; hydration; FTIR; infrared spectroscopy;

    Abstract : The production of cement is responsible forapproximately 7 % of the total CO2 emissions caused by man. To compensate for high energyconsumption and CO2 emission, thus making the utilization of concrete more sustainable,several strategies can be used. READ MORE

  6. 4. Sustainability measures in quicklime and cement clinker production

    Author : Matias Eriksson; Rainer Backman; Dan Boström; Flemming Frandsen; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; limestone; quicklime; cement clinker; sustainability; oxygen; carbon dioxide; thermal decomposition; dynamic rate thermogravimetry; predictive multicomponent chemical equilibrium calculations; mineral carbonation;

    Abstract : This thesis investigates sustainability measures for quicklime and cement clinker production. It is the aim of this thesis to contribute to the effort of creating a more sustainable modus of industrial production. READ MORE

  7. 5. Phase chemistry in process models for cement clinker and lime production

    Author : Bodil Hökfors; Rainer Backman; Bo Björkman; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process modelling; phase chemistry; cement clinker; lime; sustainability; CO2; energy;

    Abstract : The goal of the thesis is to evaluate if developed phase chemical process models for cement clinker and lime production processes are reliable to use as predictive tools in understanding the changes when introducing sustainability measures.The thesis describes the development of process simulation models in the application of sustainability measures as well as the evaluation of these models.
