Waste sector remains the largest contributor to urban greenhouse gas (GHG) emissions after the energy sector in the city level. This study aims to assess the potential of circular economy by using Black Soldier Fly (BSF) as organic agent to processing the organic waste to the value-added products fish meal and organic fertilizer in the city. The study has been conducted at organic waste management site affiliated with the Tasikmalaya City. The harvesting process for the BSF larvae (BSFL) was conducted while the co-products BSFL frass and BSFL skin were analyzed in the laboratory to determine its chemical characteristics. The result of the study shows that in average 8.33 kg BSFL has been produced from 25 kg organic waste feedstock. The highest organic carbon content was shown in the mixture of BSFL frass and skin with a value of 15.6% and followed by the BSFL frass and BSFL skin samples independently with values of 12.8% and 10.5% respectively. All maggot residues showed similar pH ranging at 6.3–6.5. The mixture of BSFL frass and BSFL skin had a higher total N content compared to only BSFL frass or BSFL skin with respective values of 5.8%, 5.2% and 2.6%. The total P2O5 content in all treatments shown almost similar values range from 3.55%, 3,12%, and 3.55% for BSFL frass, BSFL skin and the mixture of BSFL frass and BSFL skin respectively. However, the total K2O shown big discrepancy with value 1.42%, 0.53%, and 0.85% for BSFL frass, BSFL skin and mixture of BSFL frass and skin respectively. This study shown that the GHG emissions from waste in the Tasikmalaya city could be reduces by utilize organic agent such as BSF. This circular economy could create high economic value products such as BSF larvae (maggot) and co products BSFL frass and BSFL skin.
