The wastes, which have explosiveness, toxicity, infectious, and possibility to cause damage to other people's health and environments, are provided the special management municipal wastes or the special management industry wastes. All the treatment processes from collection to disposal is done under strict management. In this report, we focus on the inorganic and organic experimental waste fluid and the infectious waste among the special management municipal waste or industry waste, because of the similar toxic and chemical characteristics to that of biological and chemical weapons. Understanding how the decomposition and treatment of these wastes are actually done, we clarify the issues of the hazardous waste management and discuss on the possibility to develop the new degradation and treatment method for biological and chemical weapons.
