Market Potential of Wood Biomass Ash Utilisation in Cement Composites - Croatian Case Study

The growing trend of using biomass as a renewable energy source (RES) results in a growth of the wood biomass ash (WBA) as a by-product. Considering the increasing amount of WBA as well as the costs of its disposal, it is necessary to establish its sustainable management. The WBA quality varies depending on the biomass used in power plants, combustion technology and the location where collection of WBA is done. One of the possible solutions of the WBA´s disposal problem is an application in cement composites. Since WBA differs from the coal fly ash and does not satisfy the existing regulation for use of fly ash in cement, determination of the potential and adequacy of WBA as a cement replacement and/or mineral admixture in cement composites is needed. This paper presents detailed analysis of market conditions in Croatia regarding possible use of WBA in cement composites. Estimation of the WBA production in Croatia has been made based on data gathered from energy power plants. A survey for assessing current demands of the cement and concrete industry has been carried out and the extent to which the market is ready to accept WBA is evaluated.
