Urban Farm DB summary
A pyrolysis reactor technology (Prosiding Seminar Hasil Penelitian dan Pengabdian Kepada Masyarakat, Indonesia, 2024) converts sorted urban organic waste slurry into biochar using a self-sufficient pressure-control system with automatic temperature control and internal use of pyrolysis gas as fuel, processing waste at 400-500°C. Performance testing on soil samples showed the resulting biochar had 65-70% fixed carbon content with physical and chemical stability suitable as a soil amendment, increased soil cation exchange capacity by up to 30%, and increased soil moisture by up to 15% compared with untreated control soil. The reactor reduced organic waste volume by 50% and the biochar was reported to improve urban agricultural soil fertility and productivity.
