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

2. The radium distribution in some Swedish soils and its effects on radon emanation
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
3. Sequential 3D Integration - Design Methodologies and Circuit Techniques
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
4. Bark Biorefinery : Isolation, Characterization and Application
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
5. Cobalt and Nickel Bioavailability for Biogas Formation
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
