Memory of Fire Connecting Mountains and People - The Future of Regional Recycling by Woody Biomass and Agricultural Residues (June 2004)

In June 2004, the use of woody biomass and agricultural residues was attracting attention in Japan as a way to achieve sustainable local communities.
Boiler technology that uses construction waste and thinned wood as fuel was being demonstrated, especially in mid-mountainous areas, with the aim of both saving energy and effectively using forest resources. In Iwate and other prefectures, small boilers capable of burning wood chips with high moisture content were introduced on a trial basis, and innovations to overcome the problems of flue gas treatment and combustion efficiency were being built up.

This technology is more than just an energy-saving device. It was also a symbol of regional revitalization through local production for local consumption of energy and the fusion of forestry and energy industries. Breaking away from dependence on heavy oil and reducing CO2 emissions also led to a change in the mindset of local residents. It also served as a stepping stone for later renewable energy policies and feed-in tariffs (FIT).

At the same time, the utilization of agricultural residues was also attracting a great deal of interest. In mountainous areas, attempts to use rice straw and vegetable scraps as compost were spreading. This has improved the soil's water and fertilizer retention properties, and has been shown to be an effective substitute for chemical fertilizers. The composting process was relatively simple and functioned as a social experiment to encourage the participation of local residents.

These efforts provided an opportunity to reevaluate not only economic rationality but also the wisdom of recycling rooted in the local climate. The attempt to transform waste into resources was not merely a technological innovation, but was also a "movement to rediscover the power of local communities to survive.

Forests, fields, and human life. In 2004, Japan was at a turning point.
