that is where I got the image from. Now, we can finally call these plants... POOP PLANTS.
oh:
edit:
1: Domestic waste water heads to sewage processing plant
2: Settlement tanks separate sewage into clean water and sludge
3: Anaerobic digesters break down the waste and produce a thick, odourless waste and methane. Waste solids used as fuel or fertiliser
4: Biogas plant cleans methane to remove impurities, adds odorant to "smell like gas"
5: Clean biomethane pumped back into national network
