2. 1. Leaching, filtration and displacement washing in a treatment process for MSW combustion fly ash - laboratory scale and plant studies

   Author : Magda Wilewska-Bien; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; washing; filtration; MSW; cyclone ash; : leaching; fly ash; MSWI ash;

   Abstract : Municipal Solid Waste combustion, as one of the waste management tools, starts to play an important role nowadays in heat and energy generation. However, MSW combustion leads to generation of other wastes - combustion residues, including ashes, which require a proper management. READ MORE

   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.

   Abstract : The current work aims to make a numerical model for an engineering design of anindustrial cyclone gasifier called as the Hortlax plant with capacity of providing 2.4 (MWth)of district heating as well as 1.3 (MW) of electricity. READ MORE

6. 4. Management of ship-generated waste - illustrated from the Baltic Sea perspective

   Author : Magda Wilewska-Bien; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; shipping; fly ash; Baltic Sea; food waste; nutrients; leaching;

   Abstract : Globally around one-third of food produced for human consumption is wasted or lost. Although the food waste issues on land are being widely discussed, the food waste generated on ships seems not to receive similar attention. READ MORE

7. 5. The fate and ash transformations of phosphorus in combustion of biomass and sewage sludge

   Author : Joel Falk; Marcus Öhman; Nils Skoglund; Dan Boström; Franz Winter; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Abstract : The combustion of phosphorus (P)-rich biomass has a significant potential to increase the stock of biomass resources available for renewable heat and power production. In addition, the P-rich ashes have the potential as a fertilizer and could reduce the need for non-renewable P resources in agriculture. READ MORE
