Due to the euphoric use of »green« energy produced by biomass power plants, up to 350 000 tons of ash are accumulated as a waste product every year in Austria and the estimated costs for landfilling are 1.7 million € per year. For this reason, methods must be found for the utilization of wood ash. One solution is to use it as a stabilizing material in forest roads. The pozzolanic characteristic of ash is used to bind the gravel in the road base. Wood ash is expected to reduce the need for… Expand
Environmental impact assessment of wood ash utilization in forest road construction and maintenance--A field study.
The results indicate that, when specific requirements are met (i.e. appropriate ash quality, sufficient soil buffer capacity below the road body, and single time-point ash incorporation within several decades), wood ash application in forest road construction is generally environmentally acceptable.

Fly ash in forest road rehabilitation
Finnish forestry and bioenergy production is seeking novel uses for the fly ash deriving from biomass conversion. There are various possibilities for using fly ash in civil engineering in - cludingExpand
Preliminary screening of wood biomass ashes for partial resources replacements in cementitious materials
Abstract Worldwide there is a significant increase in amounts of wood biomass ash (WBA), a waste from wood biomass combustion process. In this case study, 21 different sources of wood biomass ashExpand
Wood Ashes from Grate-Fired Heat and Power Plants: Evaluation of Nutrient and Heavy Metal Contents
Ashes from biomass heat (and power) plants that apply untreated woody biofuels may be suitable for use as fertilizers if certain requirements regarding pollutant and nutrient contents are met. TheExpand
Geotechnical Properties of Wood Ash-Based Composite Fine-Grained Soil
It is observed in Bangladesh that there is an extensive use of wood as a solid biomass for heat and electricity production, which led to increase in the amount of combustion residues known as ash.Expand
Laboratory Evaluation of the Properties of Asphalt Mixture with Wood Ash Filler
Values of MS and MQ indicate that a 50% content of bio ash in the filler results in an increase in asphalt’s resistance to the appearance of plastic deformations and greater tensile strength and in good asphalt resistance toThe action of water. Expand
State-of-the-art applications of fly ash from coal and biomass: A focus on zeolite synthesis processes and issues
Abstract Over the years, the production of waste ash from many sources (e.g. coal, biomass, industrial, animal, and municipal solid waste) and from conventional and renewable energy technologies hasExpand
Leaching Characteristics of Wood Biomass Fly Ash Cement Composites
Wood biomass ash (WBA) represents an environmental and economic problem for energy producers, and there have been extensive studies of using WBA as a raw material in construction products. This studyExpand
Applications of Recycled Sustainable Materials and By-Products in Soil Stabilization
The notion of sustainable and eco-friendly infrastructures is gaining impetus in the geotechnical engineering research field. Nowadays, employing recycled or waste materials, obtained from theExpand
Leaching of heavy metals and barium from forest roads reinforced with fly ash
The aim of this study was to determine the effect of leaching of heavy metals (Cr, As, Cd, Cu, Ni, Pb, Zn, Co, Mo) and earth-alkaline metal, barium (Ba), on the percolation and ditch water qualityExpand


Sustainable utilisation of forest biomass for energy - possibilities and problems: policy, legislation, certification, and recommendations and guidelines in the Nordic, Baltic, and other European countries.
Abstract The substitution of biomass for fossil fuels in energy consumption is a measure to mitigate global warming, as well as having other advantages. Political action plans for increased use existExpand
