- Synopsis
- The effect of the use of waste by the cement industry on the extension of the life of final disposal sites has been described by the Japan Cement Association. However, this effect is considered not to have been evaluated accurately because the type of final disposal site and the influence of domestic demand were not taken into consideration. Therefore, a study was conducted to more accurately estimate the effect of the cement industry on extending the remaining life of final disposal sites and to clearly show its contribution. As a result, it was estimated that if the cement industry were to not use waste, the remaining life of controlled typed landfills would decrease from 25 years to 7 years, indicating the significant contribution of the cement industry to the life extension of final disposal sites.
