Many interesting reports concerning ashes were released over the years. We have compiled lists of relevant reports. Here you can also download reports directly via the web - or get tips on how reports can be ordered.

Geotechnical uses of ashes incl on landfills

>>Control and follow-up of fly ash roads - communication and acceptance
Värmeforsk Report 1191, 2011
Josef Mácsik. Tomy Edeskär, Fredrik Hellman

Stabilization of unbound layers of road structures with fly ashes is a promising technique from technical, economical and environmental point of view.

>>DIANAS utilization of waste inciniration bottom ash in bound construction materials.
Värmeforskreport 1212, 2012
Niklas Hansson 

MSWI bottom ash is a good aggregate in plain concrete.

>>Evaluation of robustness of fly ash stabilized sewage sludge    (FSS) as liner. -Durability, percolation and drainage water quality
Värmeforskreport 1219, 2012
Josef Mácsic, Märta Lendell, Karsten Håkansson

Fly ash stabilized sewage sludge (FSS) together with an overlaying geomembrane is a good dense liner in landfills.

>>Magnetic susceptibility for assessing ash constructions. Evaluating the potential of magnetic susceptibility as a method to assess state and delineation of ash construction
Värmeforskreport 1221, 2012
Göran Blomqvist, Rebecca Bertilsson, Ola Wik

The method has potential to be developed to discover where ash layers are situated in roads.

Ashes to forest and soil

>> Ash addition after whole-tree harvesting on fertiole sites in southern Sweden.
Establishment of two field trails

Värmeforsk report A-27, 1210
Ulf Sikström, Lars Högbom, Staffan Jakobsson och Eva Ring

Two field experiments were established designed for long-term monitoring, comprising several decades.

>> Leaching of wood ash, Laboratory and field studies
Värmeforsk report 1229, 2012
Per-Erik Larsson

After almost 10 years in the forest soils there still remains large quantities of the original product.

>> Leachates from wood ash – effects of storage on soil
Värmeforsk report 1217, 2012
GunnarThelin, Inger Valeur

The project shows that it is a low environmental risk to store a pile of fresh wood ash at an uncovered ground.

>> Ash based fertilization in young stands of birch and hybrid aspen
Värmeforsk report 1213, 2012

There is nothing in the material suggesting that fertilization effects of Ash+N should be less than effects of NPK.


>> Dust emissions from gravel roads built with fly ash
Värmeforsk report 1225, 2012
Göran Blomqvist, Karin Edvardsson, Mats Gustafsson och Ola Wik

Traffic on a gravel road with base layers stabilized by fly ash emitted less dust than from the reference road.

>> Accumulation of metals in vegetation established in ash constructions
Värmeforskreport 1222, 2012
Kristian Hemström, Torleif Bramryd, Ola Wik, Michael Johansson, Annika Jägerbrand

The concentrations of harmful metals in the leaves from trees and bushes grown in MSWI bottom ash lysimeters were low.

>> Ash – long-term ecotoxical risk to the environment
Värmeforskreport 1208, 2012
Magnus Breitholtz, Margareta Linde, Anja Enell Ola Wik

Similar to our earlier chemical and ecotoxicological investigations of ash, the present study show that K is dominating the toxicity of ash eluates.

>> Copper speciation in MSWI bottom ash leachate, a joint European approach for geochemical modeling
Värmeforskreport A-28, 2012
Susanna Toller, Joris van Schaik, Dan Berggren Kleja, Jon Petter Gustafsson, André van Zomeren, Rob Comans

Both the hydrophilic organic acids, and not only the fulvic acids, contribute significantly to Cu binding in MSWI BA leachates.

>>The significance of solid solution in iron (hydr)oxides for stabilztion of elements potentially harmfull to health and environment
Värmeforskreport 1198, 2011
Rolf Sjöblom, Bengt Noläng.

Some harmful metal oxides in ashes are bound in iron(hydr)oxides which explains the very low longterm leaching properities.

>> Ecotoxicological classification of ash – impact of leaching conditions and antagonistic and ecotoxic effects of macro elements on ash leachate toxicity.
Värmeforskreport 1197, 2011
Ola Wik, Magnus Breitholtz, Kristian Hemström, Margareta Linde, Sara Stiernström

MSWI-bottom ash leachates are not ecotoxic due to ecotoxic ions but somewhat to K and Ca and at high pH to Al.

>> Optimization of ash washing process
Värmeforskreport 1192, 2011
Nordmark Désirée, Lindgren Elisabet, Vamling Maria, Lagerkvist Anderss

There are a number of measures that, alone or in combination, can generate a washed MSWI fly ash that meets the requirements of a class II landfill today.


>>Maintaining the database Allaska 2009-2011
Värmeforskreport 1216, 2011
Henrik Bjurström, Solvig Grönstedt, Samira Shamsa, Ronja Biejer 2011

Public quantitative information on the properties of combustion residues is collected into the database Allaska and is made generally available on Internet in Swedish and English.

>> Synthesis of Värmeforsk´s research programme “Environmenatlly correct utilisation of ashes 2009-2011”
Värmeforskreport 1239, 2012
Strömberg Birgitta

The program 2009-2011 has funded 37 different projects in four different areas: forestry, geotechnique, environment and information. The created network has a major role in the success of the Ash programme.
