In Miyagi, fi ve holding blocks, i.e. Kesennuma, Ishinomaki, Miyagi-Tobu,
Sendai and Watari-Natori (MPG 2013a ; Taisei Corp. 2013 ), were constructed
(Fig. 17.7 ) including storage, sorting and incineration facilities, costing up to 16
billion Yen (approximately US$ 160 million at the time), each to be dismantled by
April 2014 (roughly one and half years after being built). Following decommissioning,
the land is to be used for various development purposes (Taisei Public Information,
Hajikami Plant, Kesennuma 2013, personal communication).
The Hajikami, Koizumi and Katahama debris facilities, located in the Kesennuma
block, dealt with 1.64 million tons of debris until March 2013, of which 670,000 t
consisted of tsunami debris or deposits, while the rest consisted of general disaster
waste or tsunami debris (Table 17.1 ). All of this debris was originally stored in 24
initial collecting temporary sites throughout Kesennuma City (Taisei Corp. 2013 ;
MPG 2013a ).
The main components of general disaster waste collected in the block included
wooden debris, burnable and non-burnable materials, concrete, asphalt, metals, boats
and plaster as well as soil, sand and mud. Out of all the materials, wooden debris
