Since the latter half of the 1980s, the ballast water of ships has been regarded as an issue internationally as a factor that has a major influence on the transfer and ecosystem of alien species. The Ballast Water Management Convention was adopted at the International Maritime Organization (IMO) Conference in 2004.
We are conducting research on the invasion of these alien organisms.
In addition, companies in various
fields are working on the development of ballast water management system
(BWMS). Our company has the top track record in Japan as a consultant for
application work for performance testing of BWMS and approval of BWMS.
Marine litters reaches the coast due to the tidal current. Marine litters can also have a significant impact on the landscape and ecosystem. In addition, the processing of such marine litters requires enormous costs.
However, attempts are also being made to consider these marine litters as resources and recycle them as energy. A social challenge to turn polystyrene foam (a part of marine litters) into energy is underway in Okinawa.
We are actively promoting the establish of a system for the formation of a recycling-based society, such as the conversion of coastal sea refuse to renewable energy.
