。(Prior art) In recent years, polyurethane resins have been developed into foams, elastomers,
Tolylene diisocyanate (hereinafter referred to as T), which is widely used in the fields of paints and adhesives, is the two major raw material.
, D, engineering. ) and polyether polyol usage are showing a remarkable increasing trend. However, the rapid increase in its usage has caused an increase in industrial waste, and the main industrial wastes include foam scraps from polyurethane foam manufacturing, T, D, I, waste liquid, and polyurethane foam. Examples include ether polyol waste liquid. Foam waste is generally disposed of by incineration.
- For polyethyl polyol waste liquid, mix it with waste oil or
Or they are incinerated separately, and there are no problems with the disposal of both. On the other hand, as for T, D, I, waste liquids, if they are incinerated as they are, there is a risk of emitting a flammable and pungent odor as well as a large amount of harmful gas.
The actual situation is that it is processed in the following two ways.

固化物を焼却処理する方法である。D, I is a method in which waste liquid and water are reacted to produce a solidified product, and the solidified product is incinerated.
（発明が解決しようとする問題点）
しかしながら、上記Ｔ、Ｄ、１．廃液処理ＩＫ−アって

In the former case, the urethane foam product is light and has a low density and easily scatters, so the urethane foam product is packed in bags for transportation. Since the product expands four to five times in volume, an extremely large amount of labor is required.

ととなっていた。In the latter case, the ignitability of the solidified material is poor, and when ignited, a large amount of black smoke will be generated.Moreover, most of the solidified material has urea bonds, so if it is incinerated, The amount of harmful gas (hydrogen cyanide) in the combustion gas was about 10 times or more greater than in the case of the urethane foam product.

) Stir for 4-5 minutes. Here, if a large amount of polyol is added, the viscosity of the resulting foam will increase and unreacted polyol will remain. The quantity was appropriate. The foamed solidified product obtained by such an operation has a volume of 6 to 6.
It increased in size by 4 times, and its appearance was a solidified substance that could be easily crushed by hand. Therefore, from the perspective of preventing scattering,
The foamed solidified material was placed in a plastic bag and put into an incinerator for disposal. The combustion state at that time was such that it ignited quickly like a sparkler.
