The problem of the disposal of waste pesticides is constantly increasing in acuteness with the diversification of their use and the growth of population. Their escape into the environment as a result of disposal practices must be controlled or prevented. Some waste pesticides are being stored until safe disposal methods are available; however, they cannot be accumulated indefinitely. The purpose of this project was to investigate methods of combustion applicable to disposal of pesticide residues and their containers and to devise a means for their destruction that would keep environmental pollution to a minimum. Oxidizing agents and binders generally aided the destruction of pesticides; the combination of oxidants and petroleum oil binders was no more effective than the oil binders alone. By using polyethylene, which under heating or combustion conditions softens or degrades to products of lower molecular weight, the advantages of a liner and a binder were obtained with one material. A practical system was devised that consisted of burning the pesticide in a flattened polyethylene bag on or surrounded by other combustible material. Suggestions were made concerning an improved design of polyethylene container or liner to aid in carrying out the purpose of this investigation.
