6. Steel converter slag as an oxygen carrier
Sammanfattning : Thermal conversion of fuels can be used to produce heat and power in addition to chemicals. In order to be aligned with climate targets, it is necessary that such systems do not emit carbon dioxide to the atmosphere. Carbon capture and storage (CCS) can be used together with fuel conversion systems to prevent CO2 from entering the atmosphere. LÄS MER
7. Advancing life cycle assessment of textile products to include textile chemicals. Inventory data and toxicity impact assessment
Sammanfattning : Textile products are used by almost everybody throughout the world, fulfilling basic human needs such as keeping us warm and contributing to our social position. Every year the global textile industry delivers close to 100 million metric tonnes of new products to the market. LÄS MER
8. From Science to Policy : Improving environmental risk assessment andmanagement of chemicals
Sammanfattning : A complex process like risk assessment and the subsequent risk management decision makingshould be regularly evaluated, in order to assess the need to improve its workings. In this thesisthree related matters are addressed: evaluation of environmental risk management strategies,evaluation of environmental risk assessments, and how ecotoxicity data from the open scientificliterature can be used in a systematic way in regulatory risk assessments.

9. Engineering synthetic pathways for adipic acid biosynthesis
Sammanfattning : Utilization of petroleum in consumer product manufacturing is causing irreversible environmental damage. Its impact on land, sea, and air calls for the development of more sustainable technologies based on the use of renewable materials such as lignocellulosic biomass and its conversion into platform chemicals.

10. LIGNIN HYDROTHERMAL LIQUEFACTION IN SUBCRITICAL WATER TO PRODUCE BIOFUEL AND CHEMICALS
Sammanfattning : Lignin is one of the most abundant amorphous macromolecules found in nature. Along with cellulose and hemicellulose, it forms a main component of biomass, and is mainly responsible for providing strength, rigidity and resistance to degradation. From a chemistry perspective, lignin is an important source of aromatics. LÄS MER
