Background on Plant

As of 2013 Nippon Paper is studying whether to add a 30 billion yen ($301 million) plant fueled by coal and wood at the site of its Ishinomaki paper factory.[1] The project is planned for 2017-18 and will be 149 MW in size.[2][3]

According to the environmental group Kiko Network, the Ministry of Economy, Trade and Industry judged on 7 March 2014 that an Environmental Assessment was unnecessary.[4]

In April 2015 it was reported that Nippon Paper and Mitsubishi planned to create a joint venture, Nippon Paper Ishinomaki Energy Center, to jointly develop a co-fired 149MW power plant at the site of Nippon Paper's Ishinomaki mill. Nippon Paper will provide 70% of the investment, while the remaining will come from Mitsubishi. The plant is scheduled to commence operations in March 2018, and would generate electricity using 30% woody biomass and the remaining coal. Nippon Paper said it is planning to transform its current business structure into global biomass.[5]

Construction started in December 2015 and the plant went into operation in March 2018.[6]

Though the power station remained operational, it reportedly burned majority biomass.[7]

In November 2018, the Kiko Network released a report against the production of Japanese Coal power plants, including the Nippon Paper Miyagi power station. The report specifically provided instructions for phasing out coal power plant production by 2030. The reasoning behind the report was that the coal power plants would increase Japan’s carbon emissions and be inconsistent with the IPCC’s goal of 1.5 Degrees Celsius.[8]

The Nippon Paper power station in the Miyagi prefecture of Japan was estimated to release 0.894 [MT-CO2/year] from the power-generating capacity. There would also be SOx, NOx, and Ash Dust emissions.[9] The “No Coal, Go Green! Project” released a report in March 2020, highlighting why the Mitsubishi Company that is powering the Nippon Miyagi plant should stop investing.[10]
