Remaining Capacity of Final Disposal Site
■Remaining Capacity in 1,000 ton
■Final Disposal QTY in 1,000 ton
■Remaining Capacity in Year
QTY(1,000ton)
Remaining Year
Date : Ministry of Environment
The remaining capacity in year is maintained by increseing final disposal site, recycling and volume reduction,but space capacity itself is reducing year by year. The recycling method for hydrated cake from Ready-mixed concrete plant must be standardized immediately.
