AIST has proven that PCB and other hazardous substances can be neutralized with a high degree of disintegration under the high-temperature and ultrahigh-pressure environment created by an explosion.

Based on the results of these research projects, AIST has successfully developed an unprecedented new technology, for using an explosion to neutralize abandoned chemical weapons (ACWs) produced during World War Two.

This technology was applied in the autumn of 2004 for the destruction of 57 ACWs found in Kanda Port, Fukuoka. The disposal of the ACWs took about one month and was successfully completed without any mishaps or detrimental effect to the surrounding environment. AIST is committed to continuing its research and development to find a swift resolution to this negative legacy.
