Can the waste from a sewage treatment plant be used as a fertiliser?

Yes, indeed, water from sewage plants sometimes is pured to have drinkable standards, but due to known reasons, we do not drink it. We could use it for flushing the toilets, washing cars. In Holland they release such water into the rivers, such as Rhine, and reuse it, of course for drinking purpose. No harm done. In Israel, they use it for greening the Negev desert, for irrigation. I don't know how would you use it a fertilizer. The water is pure and as such can only be used for irrigation, but with addition of fertilizers for fertilizing.

They already use Human waste to fertilize crops..They basically mix it with thousands of chemicals and call it "good enough" My father use to haul this to different areas of the country, until he scrapped his head on part of the truck that had this waste on it. He now has an unknown "growth" that they remove about 4 times a year...it has shown signs of being cancerous. The company takes no responsibility and now denies they use human waste to fertilize our food. It's funny that we donate and spend so much money on cancer research but more then ever people are getting cancer. The way we live and the way we are being poisoned by these "safe" and "effective" ways are what is causing this.

It commonly IS used as a fertilizer ....a fair amount of processing goes into it though so that it is not a bio-hazard to humans and/or the environment as a whole

actually, it is. the organic part is processed into fertilizer.

yes and it would make real good fertilizer i would reckon
