BIOMASS ASH: A STUDY OF ITS LEACHABILITY
Original language description
In recent years, the energy sector has been preparing for a transition from coal combustion to purely ecologicalgreen energy sources. This brings changes that have and will have a significant impact on the constructionindustry. One of these green energy sources is biomass (BMA). Biomass ashes generally have a high content ofchlorides, sulphates and alkalis, which complicates their use in the construction industry. From a legislativeperspective, BMA ash is classified as waste.This study focuses on the leachability of 51 BMA ash samples from six locations in the Czech Republic, producedfrom grate and fluidized bed combustion of biomass and co-combustion of biomass with coal. The main emphasiswas placed on the leachability of heavy metals and other potentially dangerous chemical substances.Simultaneously, pH, electrical conductivity (EC), total dissolved solids (TDS), soluble inorganic salts (SIS), anddissolved organic carbon (DOC) were measured. It was found that most of the BMA ashes exceed the limits forTDS, chlorides, fluorides, sulphates, chromium, molybdenum, and selenium. Additionally, most of the samplesshowed excessively high pH and electrical conductivity.
