Q (Prakasam Tata)

I did not see, in your vision, a plan to feed biosolids to human beings. Why not?

A (Richard Dick)

First of all, there is a lot of literature throughout 20th century on using biosolids as an animal crop. They used to feed biosolids to swine, cattle, and chickens. Up to 5%, they do not mind. I think I would prefer to take my sludge after the separation process. I would be happy to use proteins, but we might have a problem with the aesthetics. We certainly can use it in animal feed. One of your predecessors in Chicago estimated in about the year of 1956, that amino acids in biosolids were worth about 25,000/dry ton, if they can be separated.
