Abstract
The invention is directed to manufacturing fertilizers having commercial levels of nitrogen reacted with organic substances. The process comprises treatment of organics with acid that acidifies and heats a mix causing the hydrolysis of polymers. The acidified organic mix is injected sequentially with a nitrogen base under conditions that result in a partially neutralized melt. The sterilized and liquefied organic matter is disbursed over recycled material for production of granules in a granulator before final drying. The process is green scalable, and safe for the location of community organics processing facilities in locations without generating a nuisance to local communities. Fertilizers also provide a green, dual nitrogen-release profile when applied to crops releasing a bolus of nitrogen over one to two weeks following application followed by a continued slow or enhanced efficiency release of nitrogen over a growing season.
