Dissemination and demonstration of mercury stabilization technology

In compliance with the Minamata convention, Indonesia has banned use of metal mercury particularly for domestic Artisanal and Small Gold Mines (ASGMs) and the government has seized a volume of mercury. However due to lack of mercury stabilization technology and supporting legislation, Nomura Kohsan has been determined to introduce a pilot plant to stabilize the mercury on site, in pursuant to relevant legislation process to be facilitated through a program which will be supported by Japanese government.

Expected impact

Further, it has been expected that at least a few hundred tons of surplus mercury would be seized, which may damage both of environment and human health due probably to inappropriate management and unsuitable disposal. Nomura Kohsan’s effort to introduce mercury stabilization equipment as well as to develop local capacity is to contribute to the target 12.4 of SDGs, which stipulates to achieve the environmentally sound management of chemicals and all wastes throughout their life cycle, in accordance with agreed international frameworks, and significantly reduce their release to air, water and soil in order to minimize their adverse impacts on human health and the environment.
