“…Ca has been the major ion investigated in studies about MSW leachate (Jeison et al 2008;Onodera et al 2013;Yu et al 2001). Although the toxicity threshold of the Ca ion for anaerobic digestion of wastewater has been studied in laboratory-scale experiments, few studies have focused on the performance of anaerobic biological treatment of landfill leachate containing extremely high Ca concentrations.…”

With the increasing use of municipal solid waste incineration (MSWI) and more stringent limits on landfilling of organic waste, more MSWI bottom ash is being landfilled, and the proportion of inorganic wastes in landfills is increasing, causing the increased Ca concentrations in landfill leachate. In this research, the inhibition effect of Ca concentration on the anaerobic treatment of landfill leachate was studied using a biochemical methane potential experiment. Slight inhibition of methane production occurred when the addition of Ca concentration was less than 2000 mg/L. When the addition of Ca concentration was between 6000 and 8000 mg/L, methane production was significantly reduced (to 29.4-34.8 % of that produced by the BLK reactor), and the lag phase was increased from 8.55 to 16.32 d. Moreover, when the dosage of Ca concentration increased from zero to 8000 mg/L, reductions in solution Ca concentration increased from 929 to 2611 mg/L, and the proportion of Ca in the residual sludge increased from 22.58 to 46.87 %. Based on the results, when the dosage of Ca concentration was less than 4000 mg/L, the formation of Ca precipitates on the surface of sludge appeared to prevent mass transfer and was the dominant reason for the reduction in methane production and sludge biomass. At higher Ca concentrations (6000-8000 mg/L), the severe inhibition of methane production appeared to be caused by the toxic effect of highly concentrated Ca on sludge as well as mass transfer blockage.

There are several problems faced by small island developing states (SIDS), especially when it comes to waste management and energy production. There is little land space available for dumping and fuel has to be imported in order to meet energy demands. These problems can be mitigated by using grass cuttings from landscaping, which are often dumped, to produced biogas, which can be used as a fuel. In this study the rates of methane production of 10 different tropical and subtropical species of grasses were determined. Based on the results for 20 g/kg samples, the specific rates of gas production ranged from 2.40 ± 0.21 NmL/gFM/day (Zoysia matrella) to 6.52 ± 0.36 NmL/gFM/day (lemon grass). It was also observed that organic dry matter (oDM) loads did not correlate with methane production, suggesting that the oDM content is not necessarily an accurate indicator of a substrate's methane potential, and highlighting areas for further study. The results in this paper provide a database on the rates of methane production of grasses which are common to the tropical and subtropical regions and can be found in several SIDS. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd.
