Woody Biomass Energy

As the heat source for tourist facilities in Awara-shi as well as in Mikuni-cho, Sakai-shi, we are aiming to establish a well-connected recycling-based society by appropriately managing forests while abundantly using local unused wooden materials instead of fossil fuels as the energy sources. With Marutsu Dempa as its representative,“Awara Mikuni Woody Biomass Energy Business Association”- consisting of the forestry association, tourist facilities such as hotels and town merchant associations in Awara Onsen and Mikuni, woody boiler organizations and local financial institutions - is contracted to work on a verification project of the Ministry of Environment and the Forestry Agency (for 2011-2013).
In the future, a heat supply company using the woody biomass energy will be established in order to construct the business model of selling and buying used heat, with the Awara Mikuni Business Association as the parent entity.

Woody biomass boiler No.1
Installations of firewood and pellet stoves

A woodchip boiler will be installed at an inn in
Awara Onsen so that the heat source can be
used to supply hot water for showering and
other purposes. By implementing heat
measuring devices and remote monitoring
systems as well as providing maintenance
services, we will verify the effective table
operation. Also, a total of 6 firewood or
pellet stoves will be installed at inns in
Awara Onsen to promote the woody
biomass energy as a
region-wide initiative.

Marutsu Forest

We acquired a forest in Takeda, Manruoka-cho,
Sakai-shi, Fukui. We will verify the line thinning
as part of our initiative for effectively using
wooden fuels from a broad-leaved forest and
efficiently logging forests.
