  1. 1. Effects of future climate on carbon assimilation of boreal Norway spruce

    Author : Marianne Hall; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : bud development; climate change; empirical models; gas exchange; photosynthesis; Picea abies; seasonality; whole-tree chambers;

    Abstract : In boreal forests, the main factors limiting biomass production are the harsh climate, which combines a short growing season and low annual levels of incoming solar energy, and the limited availabilit... mery of nitrogen. READ MORE

  2. 2. Land and climate effects of bioenergy - Brazilian sugarcane ethanol and combined biofuel-district heating in Europe

    Author : Andrea Egeskog; Chalmers University of Technology; []
    Keywords : sugarcane ethanol; bioenergy; Brazil; biofuels for transport; EU; district heating;

    Abstract : According to the Intergovernmental Panel on Climate Change, use of fossil fuels is the largest source ofthe increase in atmospheric CO2. The second largest is land use change. To reach stringent climate targets,emissions from fossil fuel combustion and land use change will need to be reduced to near zerowithin a few decades. READ MORE

  3. 3. Forest biomass production potential and its implications for carbon balance

    Author : Bishnu Chandra Poudel; Mittuniversitetet; []
    Keywords : AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; Forestry and Wood Technology; Skog och träteknik;

    Abstract : An integrated methodological approach is used to analyse the forest biomass production potential in the Middle Norrland region of Sweden, and its use to reduce carbon emissions. Forest biomass production, forest management, biomass harvest, and forest product use are analyzed in a system perspective considering the entire resource flow chains. READ MORE

  4. 4. Ethanol from Sugarcane Lignocellulosic Residues - Opportunities for Process Improvement and Production Cost Reduction

    Author : Stefano Macrelli; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Bioethanol from sugarcane is a sustainable alternative to fossil fuels, and the increasing demand for fuel ethanol has prompted studies on the use of the lignocellulosic residues of sugarcane, namely bagasse and leaves, as new feedstock. This thesis describes various process designs and the economic feasibility of producing second generation (2G) ethanol from bagasse and leaves via the enzymatic route in an integrated sugarcane biorefinery, where first-generation (1G) ethanol is produced from sugarcane sugar.
