  1. 1. Seasonal and Long-Term Storage of Baled Municipal Solid Waste

    Författare :Diauddin Nammari; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pollution control; Environmental technology; Analytisk kemi; Analytical chemistry; Miljöstudier; Environmental studies; Waste storage; Poly aromatic hydrocarbons PAH ; Dioxin; Self ignition; Volatile organic compounds; GC-MS; Temperature; Interpolation; Baling; Cylindrical bales; Rectangular bales; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : Baling of MSW has been extensively used in Sweden and other countries for the storage of energy (biomass for energy) for incineration and production of either and or electricity and heat. Baling is performed in two principally different ways, leading to cylindrical- or rectangular bales. LÄS MER

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

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

    Sammanfattning : 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).

  4. 3. Dioxin emissions from small-scale combustion of bio-fuel and household waste

    Författare :Björn Hedman; Stellan Marklund; Calle Nilsson; Brian Gullett; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Source-sorted waste; Household waste; Textile; Biofuel; Firewood; Pellets; Combustion; Wood boiler; Pellet boiler; Backyard burning; Garden waste; PCDD F; dioxin; PCB; Emission factor; Källsorterat avfall; Hushållsavfall; Textil; Biobränsle; Ved; Pellets; Förbränning; Vedpanna; Pelletpanna; Trädgårdsavfall; PCDD F; dioxin; PCB; Emissionsfaktor; Environmental chemistry; Miljökemi;

    Sammanfattning : Denna avhandling behandlar rökgasutsläpp av persistenta organiska föroreningar, framförallt dioxiner, vid förbränning av fasta biobränslen och torrt hushållsavfall i relativt små anläggningar (5-600 kW) utan avancerad rökgasreningsteknik.Samförbränning av avfall och biobränsle i effektiva mindre biobränslepannor testades som en alternativ strategi till den vanligen förekommande storskaliga hanteringen och förbränningen fast hushållsavfall.

  5. 4. Short term water heat storage : studies of velocity and temperature fields and their importance for sizing of the storage

    Författare :Jan Dahl; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Sammanfattning : Short term water heat storage's have been introduced in many district heating systems. The main reason for this is the possibilities opened by the storage for optimization of the generation of heat and electricity in combined heat and power plants. LÄS MER

  7. 5. Risk of spontaneous fires at temporary storages sites for organic material, waste fuels and recyclables: Quantification and mitigation

    Författare :Muhammad Asim Ibrahim; William Hogland; Ghasem Najafpour; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temporary storage; risk of fires; spontaneous ignition; biofuels; recyclables; waste fuels; Miljövetenskap; Environmental Science;

    Sammanfattning : Economic and environmental constraints have created increasing demand for (material and energy recovery) and recycling of waste generated from households, commercial and industrial activities. A wide variety of materials waiting for sorting, recovery, recycling and disposal are stored at temporary storage sites (TSS) where physical, biotic and abiotic processes can lead the stored material to spontaneous ignition.
