In the process of determining the content of impurities, including fossil fuels, crude oil, coke, pitch, plastics, glass, slag, rust, metals, and rock dust, in charcoal and wood briquettes via microscopic examination, the question of the use of ashes from the combustion of grill fuels (taking the scale of the new national sport into account, commonly referred to as „weekend grilling”) was raised. Another reason for addressing this issue was the question regarding the use of organic additives to acidified soil (mineral) fertilizers submitted by one of the clients of the bituminous coal and reservoir rocks analysis laboratory. In addition, the manufacturer of gardening soil has also expressed an interest in an unconventional deacidifying agent; the introduction of a new product with a unique ingredient is considered as a chance to stand out from the competition. A review of the literature shows that attempts to use ashes obtained from the biomass combustion in power boilers have been made. However, due to the biomass composition and additives and pollutants used in biomass for energy purposes, the production of such mixtures has been dropped. Based on the data from numerous samples of grill fuel, which meet the requirements regarding the content of impurities set out in the PN-EN 1860-2 standard, the question of the possible use of ash obtained from charcoal and wood briquette grilling as a component for use in the production of acidified soil (mineral) fertilizers was discussed. The article will present the amount of material obtained based on the statistical sales of barbecue fuels based on the experimentally calculated ash mass resulting from the combustion of 1 kg of starting material. In addition, a logistic proposal for obtaining ash from individual grill users will be developed. On the day of the submission of the present work, the results of the chemical analysis of charcoal and wood briquettes subjected to the gasification process have not yet been obtained. However, based on the microscopic analysis, it can be concluded that the content of impurities in the examined samples is highly unlikely to prevent the use of the mentioned ashes in agriculture.
