Promoting the utilization of Unused Wood Resource

Unused wood resource is leftover timber from thinning and logging or wood residue that are unused due to curves and small size. Wood biomass power generation plants are operating in each area and the demand for wood biomass is growing following the adoption of the FIT law (Feed-in Tariff for Renewable Energy). By using unused wood resources, we can also expect an effective increase in the value of forests while promoting renewable energy. Sumitomo Forestry Wood Products has set targets for fiscal 2020 with the aim of building an efficient and safe logging system for wood leftover from logging.

New Wood Pellet Plant Established for Effective Use of Unused Forest Material

Forests are approaching the cutting cycle throughout Japan while the challenge is the cycle of these forests from harvest through use and reforestation. Encouraging further use of forests from use of unused forest materials to other wood resources helps realize a sustainable society.

The Sumitomo Forestry Group leverages the wood procurement network throughout the entire Group. This led to a joint venture with the Electric Power Development Company to establish a manufacturing and sales company for wood pellets*1 in July 2018. The new company aims for use of unused forest materials from forests in Japan*2 as fuel for power generation in addition to examining the largest wood pellet supply system in Japan for the purpose of commercialization by 2021. Proper management of forests and a stable supply of domestic timber secure sources for sustainable wood resources. Furthermore, the Electric Power Development Company reduces carbon dioxide emission by reusing the wood biomass fuel as coal and mixed fuel combustion.

Forests have a variety of public welfare benefits from the production of timber to the cultivation of groundwater, the prevention of sediment run-off and absorption of carbon dioxide. Through these efforts, Sumitomo Forestry and Electric Power Development Company promote domestic reforestation and regional revitalization as well as sustain and conserve the social welfare functions of forests by using unused forest material as renewable energy.

Effectively Extracting Unused Forest Materials for Mombetsu Biomass Power Plant

Mombetsu Forestry Office introduced Scandinavian harvesters and forwarders able to turn in small circles in 2015 to begin efforts to deliver log harvest/thinnings (wood leftover from logging) as fuel materials to the Plant.

Moreover, by selecting forestry equipment with high-level driving performance in narrow forest areas, operators are able to execute all harvesting and transport operations while on the machine. We consider this is an initiative that improves safety and will play a role even in eliminating occupational injuries.

*1 Harvester: Self-propelled high-performance forestry machine that brings together each operation to cut, de-limb, and vertically cross-cut*3 timber, which had traditionally been done with a chainsaw

*2 Forwarder: Self-propelled high-performance forestry machine that collects and feeds vertically cross-cut timber on a cargo bed

*3 Cross-cut: To cut crude timber to a standard length
