Plain Language Summary

The management of ash is an important issue internationally, as millions of tons of ashes (> 10) are produced world-wide as a result of bioenergy production. This report, headed by the International Energy Agency (IEA) under the Bioenergy Technology Collaboration Program Task 32, aims to improve knowledge sharing around ash utilization practices at an international scale by presenting the different experiences and practices across six countries (Austria, Canada, Germany, Italy, Netherlands, and Sweden). Recommendations towards improving the utilization of ash in order to improve the sustainability of bioenergy production are presented based on a summary of ash utilization practices across these six countries, along with the input of members from South Africa, Denmark, and the United Kingdom. These recommendations include the categorization of ash by source (i.e. combustion of clean forest wood, contaminated wood, straw, or grown biomass), the use of incentives to discourage landfilling, communication of successful application practices and guidelines, and the end of waste classification of ash for forest soil amendment coupled with clear guidelines and best management practices for ash utilization.
