Sažetak

The composting of organic solid waste, the mixture of fruit and vegetable leftovers enriched with night soil, was investigated in a closed thermally insulated reactor. It was found that 80.9 % of the original substrate biodegraded after 14 days. A mathematical model of the column reactor was proposed where the biodegradation rate of the organic solid waste was described using simple n- thorder kinetics. A good prediction of process performance was obtained using the proposed kinetics and experimentally obtained reaction heat.
