Abstract
Disclosed is a method for manufacturing a carbide for reinforcing rubber articles that is capable of effectively utilizing polymer waste. The method includes the steps of mixing a carbide, obtained by thermal decomposition or incomplete combustion of polymer waste and pulverized by grinding, with carbon black to obtain a mixture of the carbide and the carbon black, and granulating the mixture using a granulating machine at a rotation speed of 70 rpm to 130 rpm.
