On August 16, 2017, the Minamata Convention on Mercury, a global treaty to protect human health and the environment from anthropogenic emissions and releases of mercury and its compounds, was enacted. On April 1, 2018, in Japan, the Amended Air Pollution Control Act and its related laws entered into force. Based on the aforementioned treaty and act, the Japanese government has been regulating mercury emissions, including those coming from waste incineration flue gas. Since then, both existing and newly constructed waste incineration plants have to comply with these regulations and meet the mercury emission standards. By considering this social need to reduce mercury emissions, Mitsubishi Heavy Industries Environmental & Chemical Engineering Co., Ltd. (MHIEC) developed a mercury removal system which is not only affordable, but also meets the strict emission standards imposed on existing and newly constructed plants.
