Summary

Adding inoculation agents to municipal solid waste (MSW) composting significantly improves temperature and oxygen consumption while controlling harmful gases. Specific agents like microbial communities or horse manure accelerate organic matter decomposition into humus, enhancing the composting process.

Area of Science:

Environmental Science
Microbiology
Waste Management

Context:

Municipal solid waste (MSW) composting presents challenges in organic matter degradation and process control.
Inoculation agents are explored to enhance the efficiency and stability of MSW composting.
Key parameters monitored include temperature, oxygen consumption, organic matter degradation, and hydrogen sulfide (H2S) emissions.

Purpose:

To evaluate the effectiveness of various inoculation agents in improving MSW composting.
To analyze the impact of inoculation on composting temperature, oxygen consumption, organic matter decomposition, and H2S gas release.
To identify optimal inoculation strategies for efficient and stable composting.

Summary:

The study investigated the use of complex microbial communities, horse manure, garden soil, and sewage sludge as inoculation agents for MSW composting.
Results show that inoculation enhances composting temperature, oxygen consumption rate, and effectively controls H2S gas emissions.
Complex microbial communities and horse manure demonstrated particular efficacy in decomposing organic matter and accelerating humus formation.

Impact:

Inoculation agents significantly influence the rate of organic degradation in MSW composting.
The use of specific inoculation agents improves overall composting conditions and accelerates the conversion of waste into valuable humus.
This research provides insights for optimizing MSW composting technologies for better waste management and resource recovery.
