ID401 - ASH

Thematic training material for the use of of ashes and ash-based materials as fertilizer has been published

May 06, 2021

Ash is the burned-out solid residue powdery product after oxidative thermo-chemical processing: oxidative combustion or semi-oxidative gasification processes. Ashes are characterized as fly ash or bottom ash or a combination thereof formed through the incineration of bio-based materials by oxidation. Co-incineration is an economically viable and widely applied waste disposal route for many nutrient-rich wastes. For nutrient recovery the mono incineration of defined biomass stream is necessary to control the input of contaminants and for concentration of the nutrient content Ashes obtained through incineration can be post-processed with the aim to partly remove metals and metalloids, and to increase the availability of plant nutrients in the ash complexes.
