Abstract

Abstract The degradation of organic matter in marine sediments could be taken advantage of to produce electricity by using a sediment microbial fuel cell (SMFC) inspired system. A single solid phase microbial fuel cell (SPMFC) in which orange peel wastes were supplemented as a carbon source mixed to marine sediments produced a power of 0.33 mW and a voltage of 0.7 V. By stacking multiple SPMFCs powers of 2.08 mW were generated for a voltage of 4.6 V. The use of dewatered sludge to inoculate the marine sediment improved the SPMFCs' performance. The removal of organic matter in the SPMFC system under closed circuit conditions was very interesting, removal rates were 19%–40% from readily oxidizable organic matter,15 to 35% for loss on ignition and 22%–55% for total organic carbon, indicating the possibility of using these systems to treat solid organic wastes and produce electricity at the same time.

Key findings

  • The SPMFC system produced a power of 2.08 mW and a voltage of 4.6 V when multiple units were stacked.
  • The removal of organic matter in the SPMFC system was significant, with removal rates of 19-40% for readily oxidizable organic matter, 15-35% for loss on ignition, and 22-55% for total organic carbon.
  • The use of dewatered sludge as an inoculum improved the SPMFC's performance.
