16. Fermentation and Cultivation Technology for Improved Ethanol Production from Lignocellulose
Sammanfattning : The work presented in this thesis has been aiming at improving ethanol production from lignocellulose. Ethanol from renewable resources is receiving renewed attention due to apprehensions of global warming and dwindling oil reserves. Lignocellulose constitutes a potential raw material source for large scale ethanol production. LÄS MER
17. Techno-economic evaluation of integrated lignocellulosic ethanol production
Sammanfattning : Sweden has claimed that it wants to have a fossil-free vehicle fleet in 2030 as a milestone of its ambitious goal for 2050 to be a country with a sustainable and resource-efficient energy supply without any net GHG emissions. Production of bioethanol from plant materials is one potential method of meeting this goal. LÄS MER
18. The potential of industrial hemp (Cannabis sativa L.) for biogas production
Sammanfattning : Biofuels are currently produced from agricultural crops, and an increasing use of crops for this application is expected in the EU in the years to come. The dominating crops cultivated in the EU for biofuel production today have a relatively large environmental impact. LÄS MER
19. Recovery of Scandium using Antisolvent Crystallization in the Valorization of Scandium-containing Waste Streams
Sammanfattning : Scandium is widely dispersed in the earth’s crust and is rarely concentrated in ores, and a viable option to guarantee a secure supply of scandium is to recover the metal from waste streams of other mining and metallurgical facilities. The valorization of such streams to recover metals of value is a prerequisite to alleviate the global shortages of scandium and other rare earth elements. LÄS MER
20. Processing Lignocellulosic Biomass into Ethanol - Implications of High Solid Loadings
Sammanfattning : Fuel ethanol from lignocellulosic biomass has the potential to provide a sustainable replacement for traditional oil-based fuels. This dissertation assesses the processing of three different lignocellulosic materials – spruce, wheat straw and giant reed – at industrially relevant solid loadings. The work is divided into two main parts. LÄS MER
