1. 1. Landfills and glass dumpsites as future bank accounts of resources : waste characterization and trace elements extraction

   Författare :Yahya Jani; William Hogland; Monica Odlare; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Landfill mining; metals extraction; glass dumpsites; hazardous waste; chemical extraction; reduction-melting; Miljövetenskap; Environmental Science;

   Sammanfattning : Environmental pollution and health threats as well as scarcity of raw materials, water, food and energy are among the main challenges our world are now facing. Simultaneously, landfills and open dumpsites still are the dominant global waste disposal option even with their long term environmental impacts in case of greenhouse gases and contaminated leachates.

3. 2. The radium distribution in some Swedish soils and its effects on radon emanation

   Författare :Cecilia Edsfeldt; KTH; []
   Nyckelord :distribution; emanation; extraction; glacial till; podzol; Ra; radium; radon; Rn; sequential soil; spodosol; Th; thorium; U; uranium; variability;

   Sammanfattning : The aim of this study has been to clarify how the radiumdistribution in soils affects the radon emanation. Thedistribution of radium, uranium and thorium has been determinedusing sequential extractions. In the study, soils from twodifferent locations were investigated. LÄS MER

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sequential 3D integration; monolithic inter-tier vias; design platforms; parasitic extraction flows; RF AMS circuits; inductors; heterogeneous integration; germanium transistors; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Sequential 3D (S3D) integration has been identified as a potential candidate for area efficient ICs. It entails the sequential processing of tiers of devices, one on top the other. LÄS MER

5. 4. Bark Biorefinery : Isolation, Characterization and Application

   Författare :Isabella Kwan; Monica Ek; Åsa Emmer; Anette Larsson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Sustainability; bark; biorefinery; Norway spruce; nanocellulose; Pickering emulsion; organosolv; extraction; lignin; Hållbarhet; bark; bioraffinaderi; gran; nanocellulosa; Pickering emulsioner; organosolv; extraktion; lignin; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : To fulfill the United Nations’ 17 sustainable development goals, there is a need to transition from a petroleum-based society toward a more sustainable one which requires new solutions and the production of materials, chemicals, and energy from renewable resources. Using side-stream products from industries to produce value-added products will be economically beneficial. LÄS MER

7. 5. Cobalt and Nickel Bioavailability for Biogas Formation

   Författare :Jenny Gustavsson; Bo Svensson; Anna Karlsson; Piet N.L. Lens; Linköpings universitet; []
   Nyckelord :Biogas production; bioavailability; cobalt; nickel; sequential extraction; S XANES; 454-pyrosequencing.; Biogasproduktion; biotillgänglighet; kobolt; nickel; sekventiell extraktion; S XANES; 454-pyrosekvensering;

   Sammanfattning : Supplementation of trace metals such as Co and Ni may improve anaerobic digestion of organic material for biogas formation. Which trace metals that are needed and the quantity to apply are, at least partly, related to metal speciation and bioavailability. LÄS MER
