   Författare :Kristina Stark; Elzbieta Plaza; Bengt Hultman; Jes la Cour Jansen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ash; Phosphorus release; Phosphorus recovery; Sludge fractionation; Supercritical water oxidation; Sustainable sludge handling.; Water engineering; Vattenteknik;

   Sammanfattning : In working towards a sustainable society, recycling and recovery of products together with handling of scarce resources must be considered. The growing quantities of sludge from wastewater treatment plants and the increasingly stringent restrictions on landfilling and on agricultural use of sludge are promoting other disposal alternatives.

   Nyckelord :Supercritical CO2; Chromatography; Extraction; Mass transfer; Solubility;

   Sammanfattning : Bioactive compounds found in plants have been of interest to man since ancient times. These compounds have the ability to modulate the metabolic processes in our bodies, which suggests that they may promote better health. Bioactive compounds vary in their chemical structure, polarity, stability and biological activity. LÄS MER

5. 4. Supercritical fluid chromatography and two-dimensional liquid chromatography : From new applications to technical innovations

   Författare :Mingzhe Sun; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Lignin depolymerisation can be utilized to produce value-added aromatic compounds. One of the major challenges in lignin depolymerisation study is the development of effective analytical tools to unravel the huge complexity of the depolymerisation product mixture. LÄS MER

7. 5. Transport of Heavy Metals in Soil Subjected to an Electric Field -A Study of the Transport of Copper in Bentonite Clay

   Författare :Klas Arnerdal; KTH; []
   Nyckelord :Electrokinetic soil remediation; bentonite; copper; adsorption; electromigration; electroosmosis; pH; potential;

   Sammanfattning : This licentiate thesis addressesphosphorus release from sewage sludge, which is the first stepin phosphorus recovery. The concept ofphosphorus recovery maybe seen as a part of sustainable sludge handling in that it isa means of recycling resources without supplying harmfulsubstances to humans or the environment.
