Methods of and systems for remediating hydrazine spills, solutions and hydrazine-contaminated objects including areas thereof. Initially, an aqueous solution comprising a dicarbonyl-compound can be prepared. The aqueous solution can then be provided for application to an object contaminated with a hydrazine group compound. The hydrazine group compounds are converted to a stable organic compound as a result of a reaction of the dicarbonyl-compound and hydrazine group compound. Conversion assists in the remediation of the hydrazine group compound from the object. The stable organic compound produced as a result of the reaction between the dicarbonyl-compound and hydrazine group compound can then be treated with a metal catalyst and hydrogen to produce glutamine or a derivative thereof. Both the stable organic compound and glutamine can undergo microbiological degradation without further remedial intervention.
