Investigation of the temperature regime impact on the course of composting processes of the solid municipal waste’s organic component

Keywords: food waste, municipal solid waste, composting, mesophilic and thermophilic regimes, microbiological additive, soil


The most environmentally appropriate solutions for management of municipal solid waste recycling are recognized as minimization and prevention of environmental pollution. The international recycling system is focused on minimizing waste by raw materials’ sorting and recycling, the rest goes to recycling and composting, combustion and stockpiling. In Ukraine, the problem of waste management remains the most urgent in the field of ecological safety. In fact, hundreds thousands tons of municipal waste today are accumulated annually in landfills and dumps. Taking into account that up to 40% of the municipal solid waste relates to easily degradable organic wastes (food waste, market waste, urban greenhouses, municipal power supply, sewage systems, household waste), the removal of this part of waste from landfills through composting and the conversion of waste into secondary material resource will significantly reduce the environmental burden on actually deployed and potentially planned landfills. Aerobic composting is one of the best available technologies for an integrated waste management system by minimizing anthropogenic environmental impact, complying with the latest domestic and foreign developments, economic and practical acceptance of technology. The purpose of this work is to study the possibility of accelerating the process of composting the municipal solid waste’s food component by using microbiological additives for introduction the process as a nature protection technology in landfills. The article presents the results of the study of the microbiological additive’s influence on the process of composting the municipal solid waste’s food component in order to accelerate it in the mesophilic and thermophilic temperature regimes with controlled parameters. In order to improve the efficiency of the composting process and to compare the processes’ characteristics the soil was used as inoculum, and the soil extract was used as a microbiological additive. It was shown that the microbiological complex accelerates the composting process of the municipal solid waste’s food component by 3.3 times for the thermophilic regime and by 2.1 times for the mesophilic conditions of composting process, which testifies to the efficiency of its use in the processes of municipal solid waste recycling in order to improve the general level of environmental safety.
