Biomass Combustion and Co-firing

Options for increased use of ash from biomass combustion and co-firing


Publications

This report provides an overview on present practices in ash management from biomass (co)combustion, based on country reports for experiences in 6 member countries of Task 32, namely Austria, Canada, Germany, Italy, the Netherlands and Sweden. Other members in IEA bioenergy task 32 that contributed were South Africa, Denmark and the United Kingdom. The report consists of a short overview section, giving the main highlights and conclusions that can be extracted from the country reports. This overview also provides a separate table with the utilization practices. The country reports for Austria, Canada, Italy, the Netherlands and Sweden are added as separate appendices to this report.

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.
