Summary

EB can be applied for mutilple pollutants

treatment (SOx, NOx, VOCs, PAHs and

dioxins) from flue gas.

EB + catalyst is better effective for VOC

removal than EB or catalyst.

Material modification

Food processing

Modification of biodegradable polymers for practical

applications (as Green products)

•Crosslinking to improve thermal deformation of Dummy Lens

•Crosslinking to synthesize hydrogel for Washi improvement and

Soil Conditioner

•Degradation to synthesize Plant Growth Promoter

Environmentally-friendly products

Products for environmental remediation

Production of metal adsorbents using Graft polymerization

Development of Radiation Processed

Environment-friendly Products

•Crosslinking of Poly-lactic acid with 3 wt %

Triallyl isocyanurate to (TAIC) at 20-50 kGy to

improve thermal deformation of Dummy Lens (>

60C, deformation)

Ref.: M. Tamada,

TARRI, Japan

Obtained hydrogel

1. Swell hundreds times in water without dissolving

2. Water is not released by pressure

3. Biodegradability is maintained after crosslinking

Crosslinking of Cellulose Derivatives

30-70% Carboxymethyl cellulose(CMC) at 50 kGy

dose

Development of Radiation Processed

Environment-friendly Products

•super water absorbent (SWA) (Carboxymethyl

cellulose gel) can be applied for soil conditioner in

arid area, addition 3 % dry SWA to sandy soil in

arid area, available soil water content increased 2

times

3% SWA, 31 tons/ha

0% SWA, 19 tons/ha

TARRI, Japan

Development of Radiation Processed Environment-

friendly Products

•Decomposed marine polysaccharides such as

chitosan from crab and shrimp shells play role of the

plant growth promoter (PGP) in shoot elongation and

harvesting yield. 30-60% increase of harvesting yield

of rice, chili, potato, carrot etc. In Asian country.
