The Future of Regional Recycling Envisioned by Woody Biomass and Agricultural Residues (June 2004)
At the time of June 2004, Japan was actively seeking a sustainable energy and agricultural circulation model that utilizes local resources. First, attention was focused on small woody biomass boilers that use unused wood such as construction waste and thinned wood as fuel. As the demonstration of the boiler progressed, technical issues were identified as improving combustion efficiency and purifying exhaust gas, and high hopes were pinned on the boiler as a model that would both conserve energy and make effective use of forest resources.
In addition, composting of agricultural residues such as rice straw and vegetable scraps was promoted in mountainous areas. The use of the compost as a soil conditioner was confirmed to improve the soil's water retention and fertilizer retention capacity, and also to reduce the use of chemical fertilizers. The project was highly evaluated as an effort to realize resource recycling on a small-scale regional basis.
These technologies and practices showed the way for local communities to take the initiative in solving energy and agricultural issues at the same time.
