Since 2003, The UNEP (United Nations Environment Programme) has started programs for the prevention of mercury pollution, a problem that threatens our environment and public health on a global scale. UNEP is also heavily involved in negotiations between governments as we approach the establishment of this treaty in 2013. The major issue in this discussion revolves around the regulation of the use of mercury in products and manufacturing processes, and the importance of creating an inventory throughout that process. As we move forward, wide-scale restrictions are going to be enacted regarding the import and export of mercury between nations. As the only mercury recycling operation in Japan, here we want to introduce, in detail, the flow of Nomura Kohsans mercury recycling technologies in order to aid other nations in the prevention of environmental pollution. One of these technologies to roasting detachment recycles mercury from fluorescent lamps, a common source of lamps used around the world, in order to produce cullet for industrial use. We would also like to discuss another one of our technologies that enables us to extract mercury, zinc, manganese, Iron, and other elements from dry-cell batteries, another common household item. They are necessary things to live a modern life for people, but they contain various toxic substances. We would appreciate it if you refer to this report in order to avoid environmental pollution risk at disposal of them.
