Abstract
Provided is a method of brake fluid disposal which is characterized in that glycol-based brake fluid is recovered from vehicles, and the recovered glycol-based brake fluid is added to a grinding step of a cement material production facility. Furthermore, a method of brake fluid disposal is characterized in that the recovered glycol-based brake fluid is mixed with diethylene glycol. With these methods, it is possible to reduce troublesome works and effectively utilize the resources in cement material production facilities.
