Human sewage is not fertilizer. It’s full of drugs, plastic, and who knows whatever else people just dump down the drain. Sure the water gets filtered, but the solid waste is contaminated as fuck all.
It has to be processed to remove the junk, which also sterilizes it. Which takes energy and time, and it USED to be more cost effective for a plant in a place where LNG comes from to pull nitrogen from the air to make fertilizer.
We already have plenty of solid sewerage waste, and even agricultural waste from cows we should be reusing.
