History of Ecocement

Up to 1993
Amid Taiheiyo Cement's aggressive efforts in the environmental business, including the effective use of scrap tires, the Company began focusing on incineration residue from municipal waste and sludge from sewage, which had been placed in landfills. We believed that they might be able to be used as raw materials for making cement.
1994 to 1996
An experimental study on Ecocement was undertaken in the course of the Ministry of Economy, Trade and Industry project "Research and Development on the Advanced Treatment and Effective Utilization Technology for Domestic and Industrial Waste," and government subsidies were begun. This research project was subcontracted by the government to the Clean Japan Center (CJC) through the New Energy and Industrial Technology Development Organization (NEDO).
 Three private-sector companies (Taiheiyo Cement Corporation, Ebara Corporation, and Aso Cement Co., Ltd.) took part, forming a government-private sector joint research project.
1997
We established our Ecocement manufacturing technology based on the results of the experimental study. We reported the results after demonstrating its quality and safety from a variety of angles.
1998 to present
