Description:

One of the biggest environmental challenges facing modern society is waste management. The most common method of waste disposal is landfilling of municipal solid waste. The application of advanced microbiological techniques to the study of landfill ecosystems is of critical importance, given the increasing concerns about greenhouse gas emissions and regulatory controls. This study investigated the impact of probiotic and formation water application on biodegradation processes of solid waste in reclaimed landfills. The main ecological groups of soil microorganisms were determined during the experiment. For evaluating the direction of soil microbial processes, the following indexes were calculated: the index of mineralization-immobilization, the oligotrophy index, and the pedotrophy index. Microbiological evaluation of soil samples from the landfill revealed the positive effects of probiotic and associated formation water. The best results in microbial activity were observed upon their application. The analysis of coefficients confirmed that the probiotic and formation water application enhances the availability of nutrients in the soil of reclaimed landfills, benefiting various ecological and trophic groups of microorganisms and fostering favorable conditions for soil microbial communities. Thus, the application of probiotic and formation water could be an innovative biological approach to accelerating waste biodegradation and supporting soil restoration in reclaimed landfills.
