2. 1. Microbial Transformation of Organotin Compounds under Simulated Landfill Conditions

   Author : Annika Björn; Bo Svensson; Jörgen Ejlertsson; Bo Mattiasson; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organotin compounds; landfill simulation; PVC; Environmental chemistry; Miljökemi;

   Abstract : Mono- and di-alkyltins are used extensively as heat stabilizers for processing of poly vinyl chloride (PVC). Tin mercaptide stabilizers are some of the most effective PVC stabilizers available. The main applications for tin stabilizers are building/construction products, such as pipes, fittings, siding and profiles (windows etc. READ MORE

4. 2. Characterization of Bacterial Biofilms for Wastewater Treatment

   Author : Sofia Andersson; Gunnel Dalhammar; Bo Mattiasson; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biofilm; extracellular polymeric substances; exopolysaccharides; interspecies interactions; wastewater treatment; denitrification; phosphorus removal; Microbiology; Mikrobiologi;

   Abstract : Research performed at the Division of Environmental Microbiology has over the last years resulted in the isolation of possible bacterial key-organisms with efficient nutrient removal properties (Comamonas denitrificans, Brachymonas denitrificans, Aeromonas hydrophila). Effective use of these organisms for enhanced nutrient removal in wastewater treatment applications requires the strains to be retained, to proliferate and to maintain biological activity within theprocess.

5. 3. Change of toxicity during secondary treatment of industrial sludge containing nitroaromatics

   Author : Lillemor Gustavsson; Magnus Engwall; Anna Schnürer; Ulrika Welander; Mårten Jönsson; Bo Mattiasson; Göran Dave; Örebro universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic; aerobic; AhR agonists; CALUX; constructed wetlands; Danio rerio; embryotoxicity; genotoxicity; nitroaromatics; sludge; Environmental engineering; Miljöteknik; Enviromental Science; Miljövetenskap;

   Abstract : Wastewater treatment plants in Sweden are facing a great challenge due to the prohibition of depositing organic waste which gained legal force in January 2005. Biological and commercial available alternatives to disposal are composting and anaerobic digestion. READ MORE

6. 4. Sludge from pulp and paper mills for biogas production : Strategies to improve energy performance in wastewater treatment and sludge management

   Author : Alina Hagelqvist; Thomas Nilsson; Karin M. Granström; Bengt Månsson; Bo Mattiasson; Thomas Welander; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anaerobic digestion; pulp and paper mill sludge; methane production; energy efficient sludge management; Miljö- och energisystem; Environmental and Energy Systems;

   Abstract : The production of pulp and paper is associated with the generation of large quantities of wastewater that has to be purified to avoid severe pollution of the environment. Wastewater purification in pulp and paper mills combines sedimentation, biological treatment, chemical precipitation, flotation and anaerobic treatment, and the specific combination of techniques is determined by the local conditions.

7. 5. Exploring the Wood Adhesive Performance of Wheat Gluten

   Author : Petra Nordqvist; Eva Malmström Jonsson; Mats Johansson; Bo Mattiasson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plant protein; wood adhesive; mechanical properties; wheat gluten; soy protein isolate; gliadin; glutenin; adhesion; hydrolysis; heat treatment; AFM;

   Abstract : The increasing environmental concern has reawakened an interest in materials based on renewable resources as replacement for petroleum-based materials. The main objective of this thesis was to explore plant proteins, more specifically wheat gluten, as a binder in wood adhesives intended for typical solid wood applications such as furniture and flooring.
