  • Reduction of VOC emissions from manure
    Publication number: 20060225473
    Abstract: In a method of reducing emission of VOCs from manure, an acid is applied on the manure to lower the pH of the manure sufficiently to reduce the emission of the VOCs from the manure. Preferably, the VOC emissions are reduced by at least about 20%. The VOC emissions may be reduced by reducing microorganisms that produce VOCs in the manure. In a preferred embodiment, the acid is sodium bisulfate. The invention is applicable in particular to reducing emission of VOCs from cow manure.
