Abstract

The regenerative capacity of bamboo is very high and bamboo is noticed from the viewpoint of effective utilization of resources. Recently, bamboo charcoa1 has been produced everywhere in Japan, in what has beeome a bamboo charcoal boom. However, there are few research reports on bamboo charcoal. ln this study, the fundamental properties of bamboo charcoal, including the humiclity control capacity under different carbonizing conditions, were compared with those of wood charcoal.
The results were obtained as follows.
1)Ash content in bamboo charcoal is about 4 times greater than that of wood charcoai.
2) There is good correlation, regardless of the wood species, between carbonization temperature and electrical resistance, and it is possible to estimate the   carbonization temperature in the traditional charcoal furnace.
3)The pH of wood charcoal changes from alkaline to acid with the nise in the carbonization temperature, but the pH of bamboo charcoal maintained its alkalinity regardless of the carbonization temperature. The quantity of ash, K and Mg content in bamboo charcoa1 seems to be related to the pH.
4)The humidity control capacity in the high humidity region of barnboo charcoal is better than wood charcoal.
