A process for converting hazard explosives that are contaminating soil into reduced derivatives and thereafter converting the reduced derivatives into humic compounds by admixing the explosives contaminated soil with a natural microorganism source and with an oxidizable carbon source and subjecting the mixture to anaerobic conditions to produce an anaerobic bioremediation product containing reduced concentrations of explosives contaminants and thereafter combining the anaerobic bioremediation product with a compostable material and subjecting the second mixture to aerobic conditions to give an aerobic bioremediation product that is essentially free of explosives contaminants and their reduced derivatives.
