The sustainable management of BNR biosolids requires a holistic approach which integrates BNR liquid treatment processes, on-site sludge handling processes and off-site biosolids reuse/disposal. A market focussed biosolids reuse/disposal strategy is a key element of the sustainable management of BNR biosolids. A methodology for preparing a biosolids management strategy is presented. BNR biosolids has a number of characteristics which affect biosolids management. These include: potential for mutrient release, dewaterability, and the need for biosolids stabilisation. Current practices for sludge handling and stabilisation in Australian BNR plants are also discussed.
