Can THP Biosolids Be Composted? Why Even Consider It? Lessons from The First-ever Full-scale Pilot
Abstract
Thermal hydrolysis (TH) and aerobic composting are both established biosolids stabilization technologies with hundreds of installations worldwide. However, there are no facilities in the world that compost biosolids after thermal hydrolysis, based on the authors’ discussions with TH suppliers. This abstract presents the findings of the first known attempt to compost TH biosolids at full-scale and demonstrates that TH solids can be used to create a high-quality compost product. Additionally, the presentation will discuss under which circumstances a utility might consider composting solids after a TH process. Product samples will be available for inspection at the presentation.
