In the course of this joint research, they will install demonstration facilities in Thailand for the production of woody biomass fuel ("torrefied pellets") using torrefaction technology along with the woody biomass resources that PPPC possesses.
Torrefaction refers to a type of technology for leaving a larger quantity of calorie than is left in normal carbonization by carbonizing woody biomass at a relatively low temperature.
Torrefied pellets are superior to pellets made with only woody biomass (white pellets) or woody chips both in terms of water resistance and grindability. The increased density of energy leads to benefits such as reduced logistics costs.
Nippon Paper Industries has decided to begin demonstrative production on a scale of 8,000 tons per year in collaboration with PPPC. It will use the accumulated torrefaction technology and ultimately aim to commercialize it for market release.
The demonstration facilities for production will be installed on the premises of the mill of PPPC in the northeastern part of Thailand.
They will utilize woody biomass as a raw material from the company-contracted forested site nearby. The facilities will begin production of torrefied pellets in spring 2017, with the plan being to ascertain the potential for commercialization around the end of December of the same year after a mixed combustion experiment with a pulverized coal boiler at Kushiro Mill in Hokkaido, Japan.
