Production processes leave some scrap rubber, and carbide can be collected by carbonizing such scrap rubber. As a part of recycling, carbide is used for steel mill fuel while the study for other new applications is being carried out.
In recent years, a study was carried out on the use of collected carbide as an additive for asphalt by joint research groups including: The Department of Civil Engineering (now known as the Department of Civil Engineering and Urban Design), Faculty of Engineering, Hiroshima Institute Technology; Chu-Shikoku Branch of Kajima Road Co., Ltd.; Hiroshima City Office Ω; Project Club (a voluntary research activity group among staff members); and Nishikawa Rubber, and the project was implemented in practical use.
This furnace uses generated gas from the waste rubber after its kiln is sufficiently heated; therefore, operating fuel is not required as a good point. (Butane gas is used only when starting up the plant.)
This dry distillation technique is attracting a public attention as a recycling technique for automobile shredder residue (ASR) which remains as the shredded dusts from the scrapped cars, emerging as a social issue today.
