“…Ashes can become part of the soil backbone, or the material providing mechanical properties to the developing soil. In addition, ashes can become a fertilising material, or a component of fertiliser, ensuring physical, chemical, and biotic properties for the soil-generating backbone [10,11,12,13]. Waste applied as substrate for plants should represent specific features that are essential for the plant growth and safe for the soil and water environment.…”

The use of waste in land reclamation projects or road works is a generally applied method of waste recycling since coal bottom ash can be used in plant substrate. This paper presents the results of research on the physical and chemical properties and the toxicity of waste originating from power stations, in the form of coal bottom ash collected from pulverisedfuel and fluidised-bed boilers. To evaluate the eco-toxicological properties of waste, a series of plant growing tests were conducted, with the use of selected plant species, as well as germination tests in water extracts of waste. The latter were intended to determine whether coal bottom ash displayed cytostatic activity, while, in the case of pot experiments, the purpose was to determine the germination rates and growths of both above-ground and underground parts of plants. The test results indicated that the influence of the tested coal bottom ash on the plant development and growth depended on physical and chemical properties of that waste. The reactions of plants were also changing depending on the proportion of waste in soil.

This paper presents the results of the preliminary experiments conducted on fly ash and bottom ash samples that were collected from a fluidised-bed boiler after biomass combustion. The purpose of the research was to determine potential possibilities of the introduction of such types of waste to soil, in accordance with the ecological engineering assumptions. The following physical and chemical properties of the analysed waste were determined: particle size distribution, pH, chemical composition, and leaching. The chemical properties of the tested power-generation waste were essentially different, depending on the time of waste sample collection from the installation, despite the fact that other identical sampling conditions were observed: the same installation, the same combustion process, and the same type of fuel. To determine the eco-toxicity of the tested waste samples, the vegetation experiments were conducted that allowed to evaluate the influence of the tested waste samples on selected test plant species. The tests concerned for example the influence of fly ash and bottom ash on such physiological processes as seed germination and plant growth (the growth of both roots and shoots). The experiments indicated certain options of the introduction of the tested waste into soil. However, due to a considerable changeability of the waste composition and structure that presented a risk of the introduction of undesired pollutants into soil, including heavy metals, such use would be possible upon previous regular evaluation of the waste's physical, chemical, and eco-toxic properties.
