Sounds too good to be true, I'll wait and see if it really works or this is just like the many other "useful materials from garbage" schemes that have collapsed under the light practicality over the years. I'll stand by my cynicism until the plant has successfully operated for a year or so.
ANd BTW "dry mineral" is ash which is a real environmental headache to get rid of in large quantities. Just look at any coal fired generating plant.
Actually, no. From a white paper:
The mineral/micronutrients that comprise the typical mineral mix from the Carthage, MO plant are shown in Table 3. Of major interest are the N, P, K elements that comprise the fertilizer. The calcium in the mix comes from the bones of the animals. The N, P, K, Ca components represent nearly 80% of the total fertilizer. The mineral product acts as a naturally self-limiting, slow release soil amendment that puts the essential nutrients back in the soil. The minerals will help to rebalance macronutrients and replace depleted essential micronutrients in the soil, encouraging healthy plant growth and development.
