    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

  4. 17. Nutrient recovery from waste streams through struvite formation

    Author : Maryam Latifian; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; struvite; nutrient; phosphorus; nitrogen; wastewater treatment; anaerobic digestion; urine;

    Abstract : Eutrophication or the nutrient enrichment of water bodies, typically by nitrogen and phosphorus has adversely affected the aquatic life and the quality of water. Governments have been forced to take actions in order to reduce the release of these nutrients into the environment. READ MORE

  6. 19. Production of polyhydroxyalkanoates in biological treatment of industrial wastewaters

    Author : Simon Bengtsson; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyhydroxyalkanoates; mixed cultures; glycogen accumulating organisms GAO ; feast and famine; acidogenic fermentation; activated sludge;

    Abstract : In search of more environmentally friendly polymer materials, polyhydroxyalkanoates (PHAs) have been considered as promising candidates. PHAs exhibit a broad range of material properties, can be produced from renewable resources and are completely biodegradable. READ MORE

  7. 20. Top-down Methodology to Identify Opportunities for Industrial Symbiosis Partnerships

    Author : Joao Patricio; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular Economy; Top-down methods; Industrial Waste; Recycling; Material Inputs; Industrial Symbiosis;

    Abstract : Industries in Europe are responsible for generating approximately 190 Mtons of waste; a figure which is expected to rise, as a significant increase in the consumption of raw materials is predicted to occur in the near future. This may lead to escalating environmental problems, including resource depletion, soil degradation, and climate change. READ MORE
