Abstract
Black goo (BG) is an emerging clogging material in l with its origin and formation that remain poorly understood. This study investigated BG from gas collection and control systems (GCCS), leachate collection and control systems (LCRS) at municipal solid waste (MSW) landfills. Proximate analysis, thermogravimetric analysis (TGA), Scanning election microscopy with energy-dispersive spectroscopy (SEM-EDS), Fourier transform infrared spectroscopy (FTIR), and metal analysis by inductively coupled plasma atomic emission spectroscopy (ICP-AES) were performed. Results showed that BG is a heterogeneous material containing varying proportions of moisture, organic matter, and mineral phases. The morphology revealed Ca-Fe-Al-Si-rich deposits with agglomerated and plate-like features. While monovalent Na and K remained primarily in the mobile Leachate phase, BG is a compositionally variable organo-mineral clogging material and that metal partitioning, particularly involving Ca and Fe, may play an important role in its formation and persistence.
