True, however it supposedly is not human waste.
"When all the nutrients have been consumed, the microbes die. Agents are then added to begin clumping the microbes together. This process of settling and coagulating takes place in quiet sedimentation tanks.
After settling, the clumped microbes are removed and sent to the Dewatering and Drying building where moisture is removed using belt presses. This produces a semi-solid form similar to wet cardboard that is subsequently dried in twelve rotary driers at temperatures ranging from 900⁰ - 1200⁰F. Any surviving pathogens are killed from the extreme hot temperatures."
Being dried at At 900F+, I can't imagine there is any nutritional value to plants. It is more like sterilized dirt to me, but plants do seem to like it.
