This is all very interesting I was just bidding on taking the sludge from our local sewer plant to the new pelletization plant being built in West Palm Beach, Florida. I wanted to buy the fertilizer coming out of the plant but it was already purchased by New England Fertilizer. The EPA has stopped all spreading of sludge cake in the Okeechobee water shed and has requested that we take phosphate out of the fertilizer because it cause algae blooms in local waters. Our local sewer plant sells more reclaimed water than it takes in. Even in Florida, the swamp state, water is in short supply and talk of "recycling" water for human consumption has been mentioned in close circles. Before, deep well injection was the method of disposing of sewage. But Deep well injection resurfaces some where. Here it was in the Florida Keys. We will need some good insight and technology or as care takers of the planet we are in deep manure.
In my business we call the same crap day after day, "Déjà Poo."
