Ash Mineral Supplement

The introduction paragraph extracted from a study paper authored by; E. van Heughten et.al of NCSU, “Value of combustion ash as a phosphorus supplement in swine diets”, addresses a developing market for a by-product created when hog manure is burnt as a dry fuel.

Quote; “Environmental concerns surrounding the disposal of swine waste have prompted investigation of combustion or thermal decomposition methods for management of these wastes. Such processes occur at temperatures in excess of 1500°F and produce only energy and a sterile ash. This ash is potentially valuable as a feed ingredient since it contains minerals that typically are supplemented in animal feeds. Therefore, the objectives of this work were to characterize various ash materials, to determine growth performance and digestibility in pigs fed this ash, and to assess any health impacts on animals maintained on ash supplemented diets throughout the grow-finish period. This report presents data on ash characterization, growth performance, and nutrient digestibility.” This research confirms a fundamental of the CRENA process, that fresh dry manure will burn producing a very high flame temperature.
