Key findings: Influence of pre-treatment on macromolecule solubilization
• THP promotes solubilisation of proteins and fibres in digester feed
• THP influences composition of digestate- Different strategy for optimization?
Soluble profiles at THP and conventional sites
• Digesters receiving THP pre-treated sludge has higher residual soluble organics.
• Increased solubilization but less utilization in digester.
• Higher post-AD fugitive emissions?
