Abstract
The commercialization of biosolids as a soil amendment is recently facing challenges because PFAS and microplastics are frequently detected (or due to their potential to contain PFAS and microplastics). Technologies to destroy PFAS from biosolids, for example, are few and their implementation at a large scale is expensive and infeasible. A promising low-cost option for treating PFAS contaminated biosolids is the use of biochar to immobilize these chemicals and restrict their release to the environment. Moreover, we have found that when biosolids mixed with biomass are subjected to low-temperature pyrolysis (450ᵒC), PFAS can be entrapped into the created biosolids-based biochar and thereby immobilized. Additionally, microplastics can be also carbonized during pyrolysis and thereby destroyed. In this presentation, we will show how the biosolids-based biochar could reduce the leaching of emerging contaminants and mitigate potential contamination of groundwaters.
