Keep composting matrix in continuous collision and friction under a relatively high-temperature can
significantly accelerate the progress of composting. A bioreactor was designed according to the novel process.
Using this technology, organic fertilizer could be produced within 96 h. The electric conductivity
(EC) and pH value reached to a stable value of 2.35 mS/cm and 7.7 after 96 h of fermentation. The total
carbon/total nitrogen (TC/TN) and dissolved carbon/dissolved nitrogen (DC/DN) ratio was decrease from
27.3 and 36.2 to 17.4 and 7.6 respectively. In contrast, it needed 24 days to achieve the similar result in
traditional static composting (TSC). Compost particles with different size were analyzed to explore the
rapid degradation mechanism of food waste. The evidence of anaerobic fermentation was firstly discovered
in aerobic composting.
