A bunch of us had a company called Prime Tanning out of Maine spread sludge from animal hides of our farms. Erin Brokwitch, the woman that is a envoroment activist, filed suit of our behalf, cuz' she determined that it was killing us and we were too backward to realize it and she was gonna' take care of the big bad company doing this to us. All she accomplished was stopping the company from giving away free fertilizer. I laughed when at a meeting with her one old farmer raised his hand and said," Don't really care if it's killing me or not, I just want to know when I can get some more."
Property values crumbled for a while, she got her name in the paper, broke the company, settled out of court cuz' there was only one company on the sue list not bankrupt, farmers got nothing, lawyers and her got lots of money.
Everyone forgot about it and things settled down, we just don't get free fertlizer.
I'd use whatever sludge they would give me, human or animal. gs
