  2. 1. Mathematical modeling of municipal solid waste plasma gasification in a fixed-bed melting reactor

    Author : Qinglin Zhang; Weihong Yang; Wlodzimierz Blasiak; Halina Kruczek; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mathematical modeling; plasma gasification; municipal solid waste; fixed-bed;

    Abstract : The increasing yield of municipal solid waste (MSW) is one of the main by-products of modern society. Among various MSW treatment methods, plasma gasification in a fixed-bed melting reactor (PGM) is a new technology, which may provide an efficient and environmental friendly solution for problems related to MSW disposals.

  4. 2. Utilization of waste materials for extraction of strategic metals : a biogeochemical approach

    Author : Viktor Sjöberg; Stefan Karlsson; Bert Allard; Mattias Bäckström; Christian Ekberg; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biogeochemistry; ICP-QMS; MP AES; strategic metals; vanadium; uranium; mine waste; steel slag; shale residues; Enviromental Science; Miljövetenskap;

    Abstract : Worldwide the modern society produces vast amounts of waste materials containing strategic and valuable metals. Some of them are of substantial economic or environmental significance if controlled recovery of metals can be performed or if uncontrolled release to the environment occurs. READ MORE

  5. 3. Nano-EngineeredThermoelectric Materials for Waste Heat Recovery

    Author : Mohsin Saleemi; Muhammet Toprak; Mari-Ann Einarsrud; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Energy crisis and thermal management related issues have been highlighted in the modern century due to escalating demands for energy consumption and global warming from fossil fuels. Sustainable and alternative energy sources are an ever growing global concern. READ MORE

  6. 4. Environmental levels of thallium : influence of redox properties and anthropogenic sources

    Author : Ulrika Karlsson; Stefan Karlsson; Anders Düker; Roger Herbert; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; thallium; Tl I ; Tl III ; separation; ion chromatography; fresh water; sediment; mine waste; fly ash; redistribution; ICP-MS; Environmental chemistry; Miljökemi; Kemi; Chemistry;

    Abstract : Thallium is a highly toxic element that humans are exposed to mainly by consumption of drinking water and vegetables grown in soil with high thallium content but also through inhalation of particles in the air. Thallium is also present in fossil fuels, alloys, and in electronic utilities. READ MORE

  7. 5. Isotope Ratio and Trace Element Measurements Using Inductively Coupled Plasma – Mass Spectrometry : Method Development and Applications in Environmental Forensics

    Author : Simon Pontér; Anders Widerlund; Hjalmar Laudon; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Isotope ratio measurements; screening analysis; ICP-MS; MC-ICP-MC; multi-tracer studies; fractionation; Environmental Forensics; Tracing; Tillämpad geokemi; Applied Geochemistry;

    Abstract : Environmental Forensics is a scientific methodology developed for identifying sources, the timing of release, and transport pathways for potentially hazardous environmental contaminants. It combines a variety of analytical methods with principles derived from disciplines such as chemistry, geology, geochemistry, hydrogeology, and statistics, with the purpose to provide objective scientific and legal conclusions on the source and/or time of a contaminant release.
