Effects of Charcoal Matter and Effective Microorganism on Compost Maturity of Green Waste
The maturity of green waste is an important indicator when be used as growing media. Effects of charcoal matter (CM) and effective microorganism (EM) on compost were investigated by measuring physical, chemical and biological properties: temperature, pH, C/N ratio, HA/FA ratio and germination index (GI). Both CM and EM can accelerate the compost process, but no significant differences on the maturity evaluation were concluded between CM and EM. Both CM and EM can increase the GI and the maximum temperature by 2 V and 4 V, and EM has a better effect. CM can hold the maximum temperature 3 days longer than CK. EM reduces the pH value by 0.5. Based on this evidence, mixing CM and EM into green waste can be considered to shorten the period of composting.
