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.

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
