   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.

   Nyckelord :HUMANIORA; HUMANITIES; algal bloom; Baltic Sea; cultural eutrophication; dead zone; waste ecology; environmental degradation; environmental humanities; critical ocean studies; environmental imaginary; environmental value; more-than- human; textual analysis; visual analysis; storytelling; algblomning; Östersjön; kulturell övergödning; bottendöd; avfallsekologi; miljöförstöring; miljövetenskap; kritiska havsstudier; miljömyndighet; miljövärde; mer-än-mänsklig; textanalys; visuell analys; berättande; Historiska studier av teknik; vetenskap och miljö; History of Science; Technology and Environment;

   Sammanfattning : This dissertation researches how perspectives in western industrial societies communicate about and give meaning to environmental degradation through case studies on the causes and effects of cultural eutrophication—namely nutrient pollution, algal blooms, and dead zones—in the Baltic Sea. Utilizing this approach, this dissertation addresses the ecological problems of cultural eutrophication in marine ecosystems by exposing normative claims humans make about the Baltic Sea and its contents as well as detailing how seas that exceed human expectations may offer insights into negotiating differing perspectives, discrepancies in power, and ways of being among humans and non-humans in marine environments.
