Abstract
Waste is an increasingly common problem in most industries. In the processes of obtaining electricity and heat, a huge amount of by-products of combustion are generated. Every year, as much as 900-1000 million tons of energy waste are generated in the world, of which the EU generates about 100 million tons. Ashes from biomass combustion are characterized by a lower content of SiO2 and a greater amount of nutrients, i.e. phosphorus, potassium and magnesium in relation to ashes from coal combustion. In addition, the high content of calcium and the presence of magnesium give phyto ashes deacidification properties. It is also important to analyze the safety of using ashes for fertilization purposes in terms of the possibility of accumulation of harmful substances, including heavy metals, in plants or soils. The use of this type of waste is regulated by the Regulation of the Minister of the Environment of January 20, 2015 on the recovery of R10 (Journal of Laws of 2011, No. 86, item 476). This type of waste requires control of the content of biogenic elements. Therefore, they should be used on soils where the permissible concentrations of substances specified in the Regulation of the Minister of the Environment of September 1, 2016 on the assessment of soil surface contamination (Journal of Laws of 2016, item 1395) are not exceeded. Despite these limitations, ash can be a valuable raw material for fertilizing purposes, improving soil quality, and being a source of nutrients for plants.
