PURPOSE: To treat an organic polyisocyanate waste liquid in high operability without causing environmental pollution, by mixing the waste liquid with a waste solvent containing resin, and burning the produced solid foam. n CONSTITUTION: (A) An organic polyisocyanate waste liquid such as tolylene diisocyanate waste liquid of polyurethane foam production process is mixed with (B) a resin-containing waste solvent, e.g. a waste paint liquid containing a thinner as the solvent and a melamine alkyd resin, etc., as the resin component, a distillation residue liquid, etc., preferably containing amino alcohol as a reaction accelerator, and the mixture is left to stand for a whole day and night. The obtained foamed solid having high ignitability and combustibility is incinerated. The amount of the component B is preferably 1W5pts. per 1pt. of the component A. n COPYRIGHT: (C)1986,JPO&Japio |
