What is the very FIRST stage typically considered in a Life Cycle Assessment?
Sewage Processing
Screening: Removes large objects like rags and grit.

Anaerobic digestion: Breaks down sludge into biogas and fertiliser.
Aerobic biological treatment: Air is bubbled through effluent to remove microbes.
Exam Order: Sedimentation comes AFTER screening. Make sure you know the 4 steps in order!
