Introduction
• Viability of biosolids to agricultural land in medium/long term?
• Increased biosolids storage requirements (up to 180 days)
• Thermal drying (& pelletisation)?
• Reduced storage volume
• “Stepping-stone” to Advanced Thermal Conversion
• But thermal drying is energy intensive…and no fossil fuels, please!
• Biogas could/should be used as energy source, but:
• On an AAD site with CHPs, what effect on electricity generation?
• On an AAD site with G2G, what effect on biomethane to grid?
• And are all AAD technologies similarly affected?
• Use theoretical Mass and Energy Balances (MEBs) to assess
