6. Biological Pretreatment and Dry Digestion Processes for Biogas Production
Sammanfattning : Biogas technology has been used quite extensively to generate renewable energy from organic wastes while also recycling nutrients in the wastes and reducing harmful emissions. However, the challenges of low biogas yield from recalcitrant and inhibitory solid wastes together with high construction and operation costs of bioreactors have impeded optimal performance through this process.

8. Biogas Production from Citrus Wastes and Chicken Feather : Pretreatment and Co-digestion
Sammanfattning : Anaerobic digestion is a sustainable and economically feasible waste management technology, which lowers the emission of greenhouse gases (GHGs), decreases the soil and water pollution, and reduces the dependence on fossil fuels. The present thesis investigates the anaerobic digestion of waste from food-processing industries, including citrus wastes (CWs) from juice processing and chicken feather from poultry slaughterhouses.

9. Impact of chronic total occlusions, arterial access site, and pretreatment with antiplatelet drugs on mortality in patients with ischemic heart disease: A report from the SWEDEHEART registry
Sammanfattning : Impact of chronic total occlusions, arterial access site and pretreatment with antiplatelet drugs on mortality in patients with ischemic heart disease: A report from the SWEDEHEART registry Background Treatment of ischemic heart disease has advanced substantially in the past half-century. However, despite these achievements the survival rates in high-income countries such as Sweden have reached a plateau in the last decade. LÄS MER
10. Bioethanol Production: Pretreatment and Enzymatic Hydrolysis of Softwood
Sammanfattning : The enzymatic hydrolysis process can be used to produce bioethanol from softwood, which are the dominating raw material in the Northern hemisphere. This thesis deals with the development of the process focusing on the pretreatment and the enzymatic hydrolysis stages. LÄS MER
