Tosoh began cement production in 1953
The idea of producing cement at a soda production plant using an ammonia soda process seemed both logical and economical.
With the progression towards becoming a recycling society, Tosoh's cement business plays an indispensable role in effectively utilizing waste and by-products generated inside as well as outside the company. Every year, Tosoh accepts and utilizes hundreds of thousands of tons of such waste from construction refuse, waste plastic, and automotive and non-automotive shredder residue.
The marketing and sale of Tosoh's entire cement production has been consigned to Taiheiyo Cement Corporation, one of Japan's leading cement manufacturers.
