Advantages of recycling peat ash in the production of building ceramics

The possibilities of ash recycling from peat combustion in boiler plants have been studied. Its use as a secondary technogenic raw material in the production of construction ceramic materials is justified. Consider the chemical-mineralogical composition of peat ash, determine its influence on the physical and mechanical properties of ceramic products and evaluate the potential of using this deviation to reduce environmental impact on the environment and implement principles of circular economy. Methods: A chemical analysis of the ash obtained at «PINDSTRUP» company was carried out, determining the content of oxides of silicon, aluminium, calcium, iron and other elements. Comparative analytical methods are used, including a review of scientific sources and comparison of the data obtained with known research results in the field of industrial and agro-industrial waste treatment. Results: It was found that peat ash is characterized by high content of SiO and Al O , which provides its suitability for use in the composition of ceramic pulp. The addition of 10-20% ash contributes to lower sintering temperature, increased strength and heat insulation properties of products, as well as reducing their mass. The material is shown to be environmentally safe due to low content of heavy metals. Practical relevance: The use of peat ash in the production of building ceramics reduces the cost of production, reduces the burden on natural resources and increases the environmental efficiency of the construction industry. The results confirm the promise of inclusion of ash from burning peat in circular production cycles, which is consistent with the principles of sustainable development and resource conservation and the introduction of innovative environmentally friendly technologies into construction production.
