Bamboo charcoal is made up from pieces of bamboo, which are taken from plants three to four years old, and burned inside an oven at temperatures over 800° C. It not only provides a new way to utilize bamboo, but also benefits to environment protection by reducing the residues pollution. Bamboo charcoal is an environmentally functional material which has excellent absorption properties. Bamboo charcoal is made of bamboo by pyrolysis process. According to the types of raw material, bamboo charcoal can be classified as raw bamboo charcoal and bamboo briquette charcoal.

According to the function of bamboo charcoal, bamboo charcoal can be classified into adsorbing charcoal, humidity adjusting charcoal, healthcare charcoal, industrial charcoal and barbecue charcoal and so on. Furthermore, bamboo charcoal can be made into active charcoal. Uses

Bamboo charcoal is mainly used as fuel for cooking and drying tea in China and Japan. Most bamboo charcoal for fuel is a bamboo briquette charcoal, the rest of which is raw bamboo charcoal. Bamboo material has extraordinary micro-structure: it produces high absorptive capacity after carbonization, and becomes more effective after activation. Bamboo charcoal can be used for purifying water, eliminating organic impurity substances and smells. Drinking water sterilized with chlorine is to be treated with bamboo charcoal to remove the residue chlorine and chlorides. In addition, a process involving bamboo charcoal has recently been developed in Taiwan using nanotechnology to combine with silver and produce a textile fibre. Bamboo charcoal is known to have high porosity. Various impurities or foreign matter will be absorbed on the wide surface area of the charcoal. When air passes, and if humidity is high, the charcoal will adsorb the moisture, and air will be converted to dry. If the air is too dry, then the charcoal will discharge its moisture, thus adjusting the humidity in the air. Bamboo charcoal vinegar is extracted when making charcoal and is used for hundreds of treatment on almost all aspects. This liquid contains 400 kinds of chemical elements and can be applied in many purposes such as cosmetics, insecticides, deodorants, food processing, and agriculture. Its functions are to expel smell, kill bacteria, keep health and to nourish facial and body skin.

And for so many years, people especially in Japan uses bamboo charcoal for many purposes, from households, kitchen tools, and medicines. Application and Uses for Bamboo Charcoal
