Rising concerns about solid waste management globally necessitate the adoption of sustainable practices, particularly in dealing with organic waste, which constitutes a significant portion municipal (MSW). Composting is an effective strategy that can reduce both environmental impact and greenhouse gas emissions wastes, while producing valuable material (compost) for soil enhancement. However, presence persistent contaminants such as per- polyfluoroalkyl substances (PFAS) compost poses human health risks, challenging wastes. This study investigates fate 33 PFAS compounds two composting systems-windrow in-vessel-focusing on transformation persistence these through process, aim collecting information will support identification strategies to mitigate contamination practices. The findings indicate reductions total concentrations after composting, 88.3% 86.3% windrow in-vessel systems, respectively. Notably, certain compounds, PFBS, appeared PFPeA, became undetectable, suggesting potential leaching or transformation. Across leachate dust samples, were relatively low, only few detected each matrix. final products met Australia's proposed NEMP 3.0 guidelines. considering variation content within similar categories (feedstock), compliance regulatory limits may vary. These results highlight need continued research into behaviour during development best practices risks.
