The release of effluent into the atmosphere that results in acid rain is a key problem in pollution control. For sustainable industrial use, from both an ecological view point and also to ensure compliance with tightening international regulations on emissions control, it is necessary to develop methods to reduce the levels of harmful waste products released into the air by manufacturing processes. Takahax, developed by Tokyo Gas Co., Ltd. is a catalyst used to recover sulfur through absorption of hydrogen sulfide, which is contained in the gases produced by coke ovens, oil decomposition, rayon manufacturing, sewage fermentation, etc. Takahax has been widely used, and has played a major role in the resolution of global ecology issues as a pollution control agent.

 The catalyst for polyurethane is used in the manufacture of polyurethane foam for the production of cushions, artificial sponges, etc. This catalyst is also used as a curing accelerator for synthetic resins, such as epoxy and silicone resins.
