  1. 1. Systems Modeling Approaches to Physical Resource Management An Industrial Ecology Perspective

    University dissertation from KTH Royal Institute of Technology

    Author : Rajib Sinha; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Complex systems modeling; environmental accounting and monitoring; en- vironmental footprint; industrial ecology; pressure-based driver-oriented approach; Modellering av komplexa system; miljöräkenskaper och miljöövervakning; miljöpåverkan; industriell ekologi; flödesbaserad övervakningaktörsorienterad strategi; Industriell ekologi; Industrial Ecology;

    Abstract : Many of the present problems that we are facing arise as unanticipated side-effects of our own actions. Moreover, the solutions implemented to solve important problems often create new problems. To avoid unintended consequences, understanding complex systems is essential in devising policy instruments and in improving environmental management. READ MORE

  2. 2. Microalgae - future bioresource of the sea?

    University dissertation from Växjö : Linnaeus University Press

    Author : Martin Olofsson; Linnéuniversitetet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microalgae; algal cultivation; bioresource; bioenergy; CO2 mitigation; multi-species community approach; seasonal variation; Akvatisk ekologi; Aquatic Ecology; Bioteknik; Biotechnology; Environmental technology; Miljöteknik;

    Abstract : Unicellular microalgae are a renewable bioresource that can meet the challenge forfood and energy in a growing world population. Using sunlight, CO2, nutrients,and water, algal cells produce biomass in the form of sugars, proteins and oils, allof which carry commercial value as food, feed and bioenergy. READ MORE

  3. 3. Developing and optimizing processes for biological nitrogen removal from tannery wastewaters in Ethiopia

    University dissertation from Bioteknologi

    Author : Seyoum Leta; KTH.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecology; biological nitrogen and supphide removal; dntififying bacteria; nitrade-reducing; sulphuroxidizing bacteria; nitrate uptake rate; Ekologi; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi;

    Abstract : In Ethiopia industrial effluents containing high contents of organic matter, nitrogen and heavy metals are discharged into inland surface waters with little or no pre-treatment. Significant pollution concerns related to these effluents include dissolved oxygen depletion, toxicity and eutrophication of the receiving waters. READ MORE

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

    University dissertation from Linköping : Linköping University Electronic Press

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Rajib Sinha; KTH.; [2014]
    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; Industriell ekologi; Industrial Ecology;

    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
