Abstract

Aims: One of the best available alternatives to face the energy and environment problem is to tend renewable energies. The main aim of this study is producing biogas from garbage bioliquid (leachate). Materials and Methods: This study was conducted at wide range of organic loading rate (OLR = 0.93–25 g COD l‑1 d‑1) by varying hydraulic retention times (HRT = 23 and 12 hsr) and initial COD of 1.85–25 g l‑1. pH variations, COD, SCOD, rbCOD and VFAs degradation, biogas and methane production were considered in this study. Results: The COD removal efficiencies were in the range of 76–81% depending on loading rates applied. The maximum volumetric methane production rate (VMPR) of 5.7 l CH4 l‑1 d‑1 was achieved at the OLR of 19.65 g COD l‑1 d‑1. About 85% of removed COD during the biodegradation was converted to methane. Conclusion: The results have shown that the anaerobic sequencing batch reactor (ASBR) reactor could be an appealing option for changing composting leachate into useable products such as biogas and other energy‑rich compounds, which may play a serious role in meeting the world’s ever‑increasing energy requirements in the future.
