The prospect of hazardous sludge reduction through gasification process

Energy Prospects of Hazardous Sludge from Wastewater Treatment Facilities

“…The economic feasibility simulation was carried out to compare solid sludge management by secured landfill (existing) methods with the thermal process method. In its existing condition, the industrial estate manager issues around US $ 7020/month for sludge disposal to secured landfill through third-party services [11]. Also, about US $ 26,492/month is issued for the use of electrical energy in Jababeka's wastewater treatment facilities [11], as illustrated in Figures 7 and 8.…”

It is related to the calculation of green energy resulted from the process is assumed to be able to substitute energy requirements as much as that produced from the gasification process [11]. In total, based on the simulation results, it is estimated that there will be a reduction in costs of up to 40% if the proposed business model is actually implemented.…”

“…The thermal process of converting biomass to energy is also accompanied by a decomposition process of complex carbon into a simpler form of carbon compounds. So that, in this case, not only the conversion of biomass into energy, but also the mass reduction of sludge should be processed and managed to minimize the negative impacts that can be generated from the sludge generated by the wastewater treatment process [11].…”
