1. Co-firing animal waste, sludge, residue wood, peat and forest fuels in a 50MWth CFB boiler : ash transformation, availability and process improvements
Abstract : The direct variable costs for heat and electricity production based on solid biomass fuel combustion is approximately 3-5 times lower than the costs in a fossil fuel-oil based boiler in Sweden. In addition waste derived biomass fuels are typically much cheaper than biomass not classified as waste. READ MORE

2. Co-firing complex biomass in a CFB boiler : ash transformation, corrosion control and materials selection
Abstract : The effects of greenhouse gas net emissions on global warming, stricter legislation on waste handling, and the pursuit of ever cheaper heat- and power production are all important factors driving the introduction of complex fuels in incineration plants. However - without fundamental knowledge regarding ash transformation, corrosion control, and materials selection – this introduction of potentially economically and environmentally beneficial fuels, might instead cause economic loss and environmentally adverse effects.

3. Developing efficient industrial systems through increased integration : applications in the forest industry
Abstract : The starting point of this work is that it is possible for an industry to increase its product value and simultaneously decrease its use of resources and production of waste material if its material and energy flows are effectively integrated into a larger system. The character and the extent of a company's environmental impact is to a large extent determined in this interaction between companies and other external actors. READ MORE

4. Chlorine Cycling in Terrestrial Environments
Abstract : Chlorinated organic compounds (Clorg) are produced naturally in soil. Formation and degradation of Clorg affect the chlorine (Cl) cycling in terrestrial environments and chlorine can be retained or released from soil. READ MORE

5. Establishment and spread of non-native bark- and wood-boring beetles
Abstract : One of the biggest threats to forest ecosystems globally is the introduction and establishment of non-native species. In Sweden alone, several bark- and woodboring beetles have established populations in recent years. READ MORE
