1. Cost-Effective Pathways for Gasification-Based Production of Biofuels
Abstract : A considerable number of studies indicate that biomethane produced through gasification of lignocellulosic biomass could contribute significantly to greenhouse gas emissions reduction in the transport sector. However, the production costs are high compared to fossil-based alternatives, which has limited deployment of the technology. READ MORE

2. Biomass Pre-treatment for the Production of Sustainable Energy : Emissions and Self-ignition
Abstract : Organic emissions with focus on terpenes, from biomass drying and storage were investigated by Solid Phase Microextraction (SPME) and GC-FID and GC-MS. The remaining terpenes in the biomass (Spruce and pine wood chips) after drying were dependant on the drying temperature and drying medium used. READ MORE

3. Interactions between calcium and heavy metals in Norway spruce : Accumulation and binding of metals in wood and bark
Abstract : Waste products from the forest industry are to be spread in forests in Sweden to counteract nutrient depletion due to whole tree harvesting. This may increase the bioavailability of calcium (Ca) and heavy metals, such as cadmium (Cd), copper (Cu) and zinc (Zn) in forest soils. READ MORE

4. Fourier Transform Infrared Spectroscopy in Industrial Hygiene Applications : Assessment of Emissions from and Exposures in Wood Processing Industries
Abstract : This thesis evaluates the use of Fourier Transform Infrared Spectroscopy (FTIR) as an approach to the increasingly difficult air sampling challenges within the field of occupational and environmental hygiene. The application of FTIR is exemplified by the assessment of emissions from and exposures in the sawmill and pellet industries. READ MORE

5. Sustainable production of bio-energy products in the sawmill industry
Abstract : One of the great challenges facing society is to convert theglobal energy system to a sustainable process. Currently, 80%of the world´s energy is supplied through the combustionof fossil fuels. Not only are the fossil resources limited, theutilisation also increases the level of greenhouse gases in theatmosphere. READ MORE
