1. 6. Effects of Varying Combustion Conditions on PCDD/F Formation

   Författare :Johanna Aurell; Stellan Marklund; Sukh Sidhu; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dioxin; formation; PCDD; PCDF; MSW incineration; transient combustion; sulfur; memory effects; quench time; chlorine; combustion; polychlorinated dibenzothiophenes; NO; water; Environmental chemistry; Miljökemi;

   Sammanfattning : Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are by-products emitted from combustion sources such as municipal solid waste (MSW) incineration plants. These organic compounds are recognized as toxic, bioaccumulative and persistent in the environment. LÄS MER

3. 7. Metals in MSWI fly ash - problems or opportunities?

   Författare :Karin Karlfeldt Fedje; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HNO3; water; NH3NO4; MSW ash; pH; metals; solvent extraction; speciation; Cu; leaching;

   Sammanfattning : Incineration of municipal solid waste is a commonly used management method to take care of our waste. However, the residues produced are a problem. They often contain large amounts of potentially toxic metal compounds and soluble salts, which can cause harm to the environment and human health if released from the ash. LÄS MER

4. 8. Thermal formation and chlorination of dioxins and dioxin-like compounds

   Författare :Stina Jansson; Stellan Marklund; Mats Tysklind; Jochen F. Müller; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dioxin; dioxin-like compounds; isomer distribution pattern; homologue profile; injection; O2PLS; PCDD; PCDF; PCN; PCBz; PCPh; MSW combustion; formation; chlorination; flue gas; quench profiles; Environmental chemistry; Miljökemi;

   Sammanfattning : This thesis contributes to an increased understanding of the formation of dioxins and dioxin-like compounds in combustion processes. Although emissions to air from waste incineration facilities have been greatly reduced by the use of efficient air pollution control measures, the resulting residues (ashes and filters) are highly toxic and are classified as hazardous waste.

5. 9. Solid waste management based on cost-benefit analysis using the WAMED model

   Författare :Viacheslav Mutavchi; Jan Stenis; William Hogland; Torleif Bramryd; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economic models; economic incentives; solid waste management SWM schemes; baling economics; municipal solid waste MSW management; ecological– economic efficiency ECO-EE ; cost-benefit analysis CBA ; full cost accounting FCA analysis; the WAMED model; the COSTBUSTER model; the EUROPE model.; Environmental technology; Miljöteknik; Business administration; Företagsekonomi;

   Sammanfattning : Efficient waste management enables the protection of human health, reducing environmental pollution, saving of natural resources, and achieving sustainable and profitable management of energy. In many countries, the general guidelines for waste management are set by national or local waste management plans. LÄS MER

7. 10. Iron-based materials as tar cracking catalyst in waste gasification

   Författare :Thomas Nordgreen; Krister Sjöström; Truls Liliedahl; Rainer Reimert; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; Kemiteknik;

   Sammanfattning : The treatment of municipal solid waste (MSW) in Sweden has changed during the past decades due to national legislation and European Union directives. The former landfills have more or less been abandoned in favour of material recycling and waste incineration. On a yearly basis approximately 2. LÄS MER
