Actions against unexpected disaster○ Enormous of disaster waste: 2,720,000 tons
⇒ Secure large areas of temporary carrying-in sites.
⇒ Construction of a new treatment system by local construction/demolition/industrial waste industries⇒ Construction of a support system by officials of other cities to supplement the treatment system ofgeneral waste○ Tremendous tsunami damage
・ Very many missing persons and left properties, and disaster waste scattering across wide areas⇒ Careful sorting and removal in wide areas
・ Salt damage⇒ Recycling wood waste at the advice of an academic society and installing temporary incinerators
・ Mixing disaster waste and Tsunami sediment⇒ Thorough sorting and stable incineration by mixing with burnable○ Consideration of various environmental matters
・ Measures against pollution by asbestos, dioxins, hazardous substances, radioactive substances⇒ Monitoring and announcement to the public, and securing effective utilization
・ Measures against soil pollution⇒ Installation of water shielding sheets in the storage areas for vehicles and electric appliances ,etc.
