SUPPLY: wastewater ammonia

• 500 tonne day-1 (in UK wastewater)
• Conventional biological treatment of ammonia produces nitrous oxide responsible for 20% of work’s emissions

Recover sustainable ammonia from wastewater to decarbonise water sector

DEMAND: ammonia zero-carbon fuel

• 5.3 kWh kg-1 (lower heating value)
• 4% of global natural gas used for industrial Haber-Bosch production of ammonia
