In order to decontaminate of radioactive substances in agricultural lands and forests, we are developing the densification technologies for the polluted bulky biomass. In the primal study, comminution and pelletization in the small scale were carried out for woody branches and leaves obtained from forest in FFPRI (Ibaraki and Tokyo). As a result, densification ratios were from 1/3 to 1/8 by comminution and from 1/6 to 1/25 by pelletization. By mixing wood part with leaves and branches, the mixed pellet showed enough durability. Densification test for herbaceous and woody biomass in a larger scale (200kg/h of feedstock) is in progress at Yamakiya district in Kawamata-town. Fukushima Prefecture, in order to design the commercial plant.
