چکیده مقاله
Wastewater treatment protects public health But it also hides a quiet story, one that’s often ignored Inside its pipes and digesters, gases like methane CH₄ , nitrous oxide N₂O and carbon dioxide CO₂ are released bit by bit into the air They’re small in volume, but they matter a lot This review looks at Tehran’s wastewater sludge biogas systems and ties local insight to global evidence Drawing from recent works, it explores how emissions form, where they come from, and what can be done to reduce them Results suggest that wastewater treatment contributes about 1 3% of global GHG emissions and maybe more than we think Upgrading Tehran’s plants with gas tight digesters, CHP units and thermal hydrolysis could cut those emissions by half or better while creating energy instead of losing it
