Abstract A laboratory study was carried out to obtain data on the influence of external carbon source on biostabilization-biodrying of kitchen waste. Two different external carbon sources (cornstalks and wood peat) were used to bio-dried with kitchen waste. A control treatment was studied using kitchen waste without a external carbon source. The two treatments with external carbon sources reduced the time taken to reach the high temperature, the highest temperature of three treatments could reach above 70℃. After 21d bio-drying, the moisture content decreased 15.25%, 28.0% and 20.3% for the control, adding cornstalks and wood peat treatments, respectively. The organic matter degraded 26.8%, 19.3% and 15.1%, respectively. The moisture content significantly positively correlated with organic matter content. No leachate was produced in the adding cornstalks treatment, whereas leachate was produced at a rate of 0.16 and 0.04kg/kg in the control and adding wood peat treatments, respectively. The water removal per initial raw waste was 0.40, 0.54 and 0.42kg/kg for the control, adding cornstalks and wood peat treatment, respectively. The water loss significantly positively correlated with temperature. The initial low calorific value of kitchen waste was 266kJ/kg, after 21d bio-drying, the moisture content decreased, the low calorific value increased to 1331kJ/kg. The treatments of adding cornstalks and woody peat showed the higher low calorific value, the final low calorific value of bio-drying product were 8400 and 6331kJ/kg.

Key words： kitchen waste bio-drying cornstalks woody peat moisture removal rate calorific power
