In this study, a lab-scale experiment was conducted to derive the optimal torrefaction conditions for upscaling food waste torrefaction to generate solid fuel. Basic characteristic analyses (a proximate analysis, elemental analysis, calorific value and thermogravimetric analysis) were conducted and further used to develop experimental conditions during upscaling. Based on the characteristics analysis, the experiments were conducted by varying the heating rates by 5, 10 and 15oC/min, varying the torrefaction temperature from 200 to 550oC at an interval of 50oC and varying the torrefaction residence time from 0 to 50 minutes at an interval of 10 minutes. The heating rates were varied and only carried out for the combustion experiments of the torrefied product at a temperature range of 50 to 800oC. The results show that the optimal torrefaction temperature and residence time of food waste torrefaction were 250 ~ 350oC and 30 ~ 40 minutes, respectively.
