Composting technology and product analysis based on the results of a pilot project in Lviv (Ukraine)

Reducing the volume of solid waste disposal is the main task of Ukraine's modern waste management system.The significant share of organic fraction in municipal solid waste necessitates the use of effective methods for its management.Among the sustainable methods of organic waste treatment, composting holds a special place.This research is aimed at analyzing the environmental impact of industrial aerobic composting technology on the environment and the quality of the resulting product (compost) based on the results of a pilot project, which was first implemented in Ukraine in the city of Lviv.The impact on atmospheric air was analyzed by analyzing the dynamics of pollutant concentrations, measuring noise and vibration levels at the boundary of the sanitary protection zone of the composting station.The impact on water bodies was assessed by recording static and dynamic groundwater levels in a technical well.Physicochemical, microbiological, and antiparasitic indicators and the content of heavy metals determined the quality of the resulting compost.All studies were conducted following standardized methods.The research results were statistically processed using a standard statistical package and compared with the approved standards.It was established that the composting technology does not pose significant environmental risks to the air and groundwater and that the composting product meets the requirements of organic fertilizers.Matured compost is environmentally safe and suitable for use in agriculture.The experience of implementing a pilot project of aerobic industrial composting of organic waste in Lviv can be implemented in other cities of Ukraine to develop sustainable practices for managing the organic fraction of municipal solid waste.
