Report: Commercial Life Cycle Assessment for Loganholme Gasification Facility (PDF 205KB)
This report summarises the Life Cycle Assessment (LCA) undertaken for the Logan City Council Gasification Facility project. This report explains the life cycle of greenhouse gas inputs and emissions during the treatment and disposal of biosolids at Loganholme WWTP.
Logan City Council (LCC) operates the Loganholme Wastewater Treatment Plant (WWTP) at Logan, southeast Queensland, which is the largest of its 4 WWTPs. Each WWTP produces two products, namely treated wastewater and excess sludge (biosolids). Currently all of the biosolids produced at Loganholme WWTP are mechanically dewatered on belt filter presses and trucked off-site for reuse on agricultural land about 250 km away. LCC, with financial support from the Australian Renewable Energy Agency (ARENA), conducted a semi-full-scale trial of biosolids gasification in 2020 at the Loganholme WWTP, and this trial was very successful, resulting in a commitment from LCC to installing a full scale commercial biosolids gasification facility at their Loganholme WWTP for operation in 2022.
