1. Chemical substitution with a life cycle perspective: The case of per- and polyfluoroalkyl substances in durable water repellents
Sammanfattning : The aim of the research presented in this thesis was to support the process of substitution of side-chain fluorinated polymers in durable water repellents (DWRs), that give rise to emissions of hazardous per- and polyfluoroalkyl substances (PFASs). The focus was on: i) the provision of improved decision support regarding the environmental and human health performance of alternatives, and ii) public readiness for substitution and what messages can motivate consumers to voluntary substitution.

2. Accident Risk and Environmental Assessment : Development of an Assessment Guideline with Examination in Northern Scandinavia
Sammanfattning : In environmental impact assessment (EIA), accident risk should be considered as one impact. However, few studies have compared assessed risk levels with documented accidents. There is thus a need for assessing accuracy of risk assessment methodologies. LÄS MER
3. Risk of spontaneous fires at temporary storages sites for organic material, waste fuels and recyclables: Quantification and mitigation
Sammanfattning : Economic and environmental constraints have created increasing demand for (material and energy recovery) and recycling of waste generated from households, commercial and industrial activities. A wide variety of materials waiting for sorting, recovery, recycling and disposal are stored at temporary storage sites (TSS) where physical, biotic and abiotic processes can lead the stored material to spontaneous ignition.

4. Managing chemical risks in the EU : Data use and new approaches for decision-making
Sammanfattning : Man-made chemicals benefit our living standards, but exposure to the (most) harmful ones can lead to negative, irreversible effects on human health and the environment. The risk management of harmful chemicals aims to protect human health and the environment from unacceptable risks. LÄS MER
5. Environmental, health, and safety assessment of chemical alternatives during early process design: The role of predictive modeling and streamlined techniques
Sammanfattning : Industrial chemicals are important for many aspects of modern life, though they can be harmful to the environment and human health. Environmental or safety concerns identified during the early design and selection of chemicals could motivate choices as to safer alternatives and process setups. LÄS MER
