Abstract
Methods, compositions, and devices for alleviating the problems of toxic discharge of aldehydes present in waste streams are disclosed. The methods relate to reducing neutralized aldehydes wherein the neutalized aldehydes are formed by treating aldehydes with amino acids and thereinafter are reduced. These reduced, neutralized aldehydes do not revert back to toxic aldehydes, but form amino acids and thus allow waste containing aldehyde to be more environmentally safely disposed.
