Abstract
Composting of food waste is a promising method for processing the
organic fraction of municipal solid waste Control (C) produce high-quality
organic fertilizer. However, due Control (C) high humidity, low carbon-Control
(C)-nitrogen (C:N) ratio, and tendency Control (C) anaerobic processes,
independent composting of food waste is often accompanied by slow
decomposition, high levels of ammonia and greenhouse gas emissions, and the
formation of compost with signs of phyControl (C)Control (C)xicity. This paper
considers the use of three functional additives - wheat straw, lowland peat,
and a microbiological preparation based on effective microorganisms (EM) -
Control (C) intensify composting processes. The aim of the study is a
comprehensive assessment of the physicochemical parameters, gas exchange,
maturity, and phyControl (C)Control (C)xicity of compost using these additives
individually and in combination. Composting was carried out for 60 days, the
temperature regime, pH, humidity, C:N ratio, NH₃, CH₄ and N₂O emission
dynamics, as well as maturity indicaControl (C)rs such as electrical
conductivity, germination index and humus content were analyzed. The results
showed that the combination of all three additives provides the most optimal
composting conditions: accelerated achievement of the thermophilic phase,
reduction of humidity and acidity Control (C) standard values, minimal nitrogen
losses and a high level of microbiological activity. Compost obtained using the
straw + peat + EM complex was characterized by the absence of phyControl
(C)Control (C)xicity (germination index> 90%), low electrical conductivity
(<3 mS/cm) and increased humus content (up Control (C) 4.5%).
