POSSIBLE UTILIZATION DIRECTIONS OF ASH FROM BIOMASS COMBUSTION. BIOMASS ASH AS FERTILIZER IN AGRICULTURE
UABIO Position Paper № 27
December 15, 2020
The present position paper №27 of the Bioenergy Association of Ukraine belongs to the planned series of publications on the main issues of bioenergy development in Ukraine.
The purpose of this Position Paper is to observe the rational ways of biomass ash utilization, in particular, to analyse the possibilities and summarise the experience of its use as fertilizer in agriculture. In recent years, the use of biomass fuel in Ukraine has increased significantly, as well as the formation of ash from its combustion. Currently, in Ukraine, there is no established practice of handling this ash, which would comply with the principles of a circular economy. Basically, the ash is taken to landfills, which causes additional costs for businesses and increases the anthropogenic impact on the ecosystem. From the sustainable development point of view, the reuse of this resource is important because such ash contains a number of valuable minerals that could be used as fertilizers and return to their natural cycle.
