Globally, interest in biosolids carbonisation as an alternative to agricultural reuse or incineration has grown rapidly over the last decade. Various drivers are cited for that interest, including concerns about emerging microcontaminants in biosolids, increasingly constrained sludge disposal pathways, biosolids upgrades and transport cost minimisation, emerging reuse pathways for biochar products, and the potential carbon sequestration benefits of biochar. As part of Stantec, we have had firsthand experience in delivering detailed designs for biosolids carbonisation facilities including at Loganholme in Brisbane, Australia, and the Riverstone WRRF upgrade in Sydney, Australia. These projects highlighted two major challenges faced by clients. First, the various drivers can be competing, and the priority of objectives, together with existing site configuration, sludge characterisation, and utility experience operating dryers and carbonisers, can directly affect the selection of drying and carbonisation equipment and system configuration. Second, the complexity of integrating these systems into an existing wastewater treatment facility, including the number of ancillaries required to ensure safe and reliable operation, is frequently underestimated. This presentation analyses the interactions and trade-offs between the various drivers and demonstrates their implications for equipment and process selection. A prioritisation tool will also be presented for selecting the most appropriate technology and system configuration (for example, integrated system vs separate drying and carbonisation, and gasification vs pyrolysis). In addition, the presentation aims to outline requirements for asset integration, material handling and storage, and other ancillaries required for a reliable, safe operation. This will act as a checklist for clients, ensuring that critical elements are incorporated into project estimates and planning for future carbonisation projects. The intended outcome of this presentation is to produce a set of practical tools that planners and designers can apply for robust technology selection, effective project planning, and the success of future carbonisation projects.
