  2. 1. Systems Aspects of Increased Swedish Waste Incineration

    Author : Jenny Sahlin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biological treatment; incineration tax; waste management; waste import; value of households’ time.; waste incineration; district heating; MSW; landfilling ban; recycling;

    Abstract : Abstract Recent bans on landfilling of combustible and organic waste in Sweden have resulted in an increase in alternative waste treatment, especially waste incineration with energy recovery. This thesis elucidates how the current increase in Swedish waste incineration affects and is affected by the two systems to which it belongs: the waste management and the energy systems. READ MORE

  4. 2. A Systems Engineering Approach to National Waste Management

    Author : Maria Ljunggren Söderman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste management planning; biological treatment; district heating; global warming potential; environmental impact; material recovery; systems engineering; energy recovery; modelling; waste management;

    Abstract : During recent decades, waste management has gradually shifted focus, from waste disposal to integrated waste management of potentially valuable resources and residues. The number and variety of waste streams to handle is large, as well as the diversity of treatment options available. READ MORE

  5. 3. Microalgae : future bioresource of the sea?

    Author : Martin Olofsson; Catherine Legrand; Jukka Seppälä; Linnéuniversitetet; []
    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

  6. 4. Household food waste management – Evaluations of current status and potential improvements using life-cycle assessment methodology

    Author : Anna Bernstad; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste management; household waste; food waste; life-cycle assessment; anaerobic digestion; systems analysis;

    Abstract : An increased understanding of the world’s limited resources and the negative environmental impacts connected to solid waste management has in recent years increased interest in separate collection and treatment of organic waste in many parts of the world. As an example, increased biological treatment of organic waste is an explicit goal within the Swedish national solid waste management strategy (SEPA, 2006) and the national environmental objectives state that 35% of all organic household waste should be treated biologically by 2010 (SEPA, 2007).

  7. 5. Bioremediation of Toxic Metals for Protecting Human Health and the Ecosystem

    Author : Aminur Rahman; Abul Mandal; Jana Jass; Björn Olsson; Pawel Kaszycki; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Heavy Metals; Pollution; Accumulation; Remediation; Human Health; Bacteria; Genome Sequencing; de novo Assembly; Gene Prediction; Biology; Biologi; Bioteknik;

    Abstract : Heavy metal pollutants, discharged into the ecosystem as waste by anthropogenic activities, contaminate drinking water for millions of people and animals in many regions of the world. Long term exposure to these metals, leads to several lethal diseases like cancer, keratosis, gangrene, diabetes, cardio- vascular disorders, etc. READ MORE
