ABSTRACT:
System and method for processing an effluvia gas containing NO.sub.X and sulfur dioxide to produce an enriched fertilizer. The gas is brought into contact with a host liquid and calcium oxide to convert the NO.sub.X to calcium nitrate and the sulfur dioxide to calcium sulfate, and the liquid containing the calcium nitrate and the sulfur dioxide is then passed through a bed of horse manure media so that the calcium nitrate and the sulfur dioxide accumulate in and thereby enrich the media for use as fertilizer.
