%X Household food waste management and treatment has been recognised as a significant issue worldwide and at a European Union level. Source-separation of household food waste following drying at source presents a viable solution to this problem. The present research aims at investigating the effect of drying of model household food waste at different temperatures (i.e. 63£¿¡À3£¿¡ãC and 83£¿¡À3£¿¡ãC) on its biochemical methane potential. The drying process was carried out using a prototype household waste dryer. The model sample consisted of 77%w/w vegetables and fruits (48%w/w and 29%w/w, respectively), 12%w/w pasta/rice, 6%w/w meat and fish, 3%w/w bread and bakery and 2%w/w dairy. Moreover, drying at the same temperatures was applied for two household food wastes samples with different composition, in order to assess the influence of the samples¡¯ composition on both the drying process and the methane generation. For all temperatures used, the higher %w/w mass reduction was observed for model waste (MD) (67.39%w/w and 75.79%w/w for 63£¿¡ãC and 83£¿¡ãC, respectively), then for rich-in-protein content (PRO) (66.18%w/w and 69.73%w/w for 63£¿¡ãC and 83£¿¡ãC, respectively) and finally for rich-in-fat content (FAT) samples (54.35%w/w and 66.31%w/w for 63£¿¡ãC and 83£¿¡ãC, respectively), which confirmed the effectiveness of the drying process. The biochemical methane potential experiments have confirmed that the substrate produced the highest methane yields was the FAT, producing 524.25£¿¡À2.86£¿L£¿CH4£¿kg-1 volatile solids
