That’s why bamboo is not used as much and the bamboo production areas in Japan are becoming untended. And, this causes some problems such as invasions and expansions into neighboring forests, decreases in river’s cultivation functions, and a decrease in biological diversity. To resolve these problems, we need to reduce the number of bamboo trees in certain areas. Wood from these trees can be used in the study of water purification methods using bamboo charcoal and the study of construction materials using blasted bamboo fiber which are carried out at the National Institute of Technology, Akashi College. Both of these studies have shown routes to the effective use of bamboo. But, they have fallen short on sharing knowledge about their influence on the environment. In this article, we carry out the LCA (Life Cycle Assessment) of these studies. LCA is a method of evaluating environmental influence. As the result of LCA, in study of water purification, the total amount of CO2 emission was 23.279 kg-CO2/5 kg.And, in a study of construction materials using blasted bamboo fiber, it was proven that canceling drainage made the water environment worse.
