Publications

This IEA Bioenergy Task 32 report provides an overview on present practices in ash management from biomass (co)combustion, based on country reports for experiences in different member countries of Task 32. On a worldwide level, only a limited number of guidelines with best practices were developed in the field of ash management. To strengthen utilization possibilities on a supranational scale, improved knowledge exchange and sharing are required. This report shows the extent of existing practices and differences in application. On some aspects, harmonization efforts may be required (such as the use in forests) but generally this report is meant to form a starting point for improved knowledge sharing.
