Case studies on developing local industry by using hot spring water and geothermal energy

We have investigated the new ways to develop local industries by using hot spring water, geothermal water and geothermal energy from the Matsukawa Geothermal Power Plant in Iwate Prefecture, which is the first geothermal power plant established in Japan. The new dyeing technique, called {open_quotes}Geothermal Dyeing{close_quotes} was invented in which hydrogen sulfide in the water exhibited decoloration effect. By this technique we succeeded to make beautiful color patterns on fabrics. We also invented the new way to make the light wight wood, called {open_quotes}Geo-thermal Wood{close_quotes} by using hot spring water or geothermal water. Since polysaccharides in the wood material were hydrolyzed and taken out during the treatment in the hot spring water, the wood that became lighter is weight and more porous state. On the bases of these results, we have produced {open_quotes}Wooded Soap{close_quotes} on a commercial scale which is the soap, synthesized in the pore of the treated wood in round slice. {open_quotes}Collapsible Wood Cabin{close_quotes} was also produced for enjoyable outdoor life by using the modified properties of Geothermal Wood.
