Kirk here. A facility is being built in Yatsushiro to derive energy from woody biomass (not to be confused with facilities intending to produce energy from Woody's biomass ;) ).

First of all, a quick definition of woody biomass:

--- start quote ---
Woody biomass is biomass derived from trees. It can be classified into construction scrap wood, sawmill residues, and forest residues (such as branches and leaves shed in the mountains).

I became aware of this project through the following article:

--- start quote ---
Nippon Paper also operates the 149MW Ishinomaki Hibarino biomass power plant in northeast Japan's Miyagi prefecture and the 6MW Yatsushiro biomass power plant in south Japan's Kumamoto prefecture.

However, the "operates" statement seems to be inaccurate in regard to the Yatsushiro plant, as it is not scheduled to start to function until 2024:

--- start quote ---
The Project Company will construct and operate “Yatsushiro Biomass Power Plant,” a wood-burning biomass power plant that will generate 75 MW and aims to commence operation in June 2024.

Woody biomass has its promoters and detractors:

--- start quote ---
Energy from woody biomass can be very positive for the climate, particularly when applying sustainable forest management practices, and when the biomass is used efficiently.

--- start quote ---
Current biomass policy frameworks are not fit for purpose and require substantial changes to ensure they contribute to mitigating climate change rather than exacerbating it.

Woody biomass particles also display anisotropic behavior where physical properties depend on whether they are measured along, across, or tangential to the grain of the wood.
