Biomass Ash

Biomass ash is produced by combustion of biomass for heat and power production. It is produced in boilers of different size and combustion technology. For the ash management requirements by the Industrial Emissions Directives as well as best practises for utilisation according to the waste hierarchy in the Waste Directive have to be considered by the producers. On the other hand technical and environmental requirements for the use of such materials have to be met and end-users need reliability in availability, quality and finally also on legal safety for use.

The first VGB Biomass Ash Workshop in 2015 focussed technologies in production and processing of biomass ash and focussed the use for forest liming, developments for easy distribution of pellets and quality schemes for this application.

The workshop in 2017 continued with basic developments in regulations, especially based on the Circular Economy initiative, basic research work and field test of fertilizers s as well as option to serve forest owners needs in forest liming and respective requirements.

This upcoming workshop will concentrate on the various examples to use biomass ash especially for fertilisation and liming in the Nordic countries. But also regulatory developments as e.g. from the Strubias project for revision of the fertiliser act will be presented. The workshop aims in information of existing and ongoing works from research to regulatory aspects and will highlight results of field tests and regular use. It is for bridging gaps of knowledge for beneficial biomass ash utilisation in the different European member states.
