Bamboo charcoal

Bamboo charcoal is made up of pieces of bamboo, which are taken from plants five years or older and burned inside an oven at temperatures over 800 to 1200 °C. It benefits environmental protection by reducing pollutant residue. It is an environmentally functional material that has excellent absorption properties.[citation needed]

Bamboo charcoal has a long history in China and has been documented as early as 1486 AD during the Ming Dynasty in Chuzhou Fu Zhi.[citation needed] Later, it was also mentioned in the Qing Dynasty during the rule of Kang Xi, Qian Long and Guang Xu.[citation needed]


Bamboo charcoal is made of bamboo by means of a pyrolysis process. According to the types of raw material, bamboo charcoal can be classified as raw bamboo charcoal and bamboo briquette charcoal. Raw bamboo charcoal is made of bamboo plant parts such as culms, branches, and roots. Bamboo briquette charcoal is made of bamboo residue, for example, bamboo dust, saw powder etc., by compressing the residue into sticks of a certain shape and carbonizing the sticks. There are two equipment processes used in carbonization, one is a brick kiln process, and the other is a mechanical process.


Bamboo charcoal is mainly used as fuel for cooking and drying tea in China and Japan.[citation needed] Most bamboo charcoal for fuel is bamboo briquette charcoal, and the rest is raw bamboo charcoal.[citation needed] Bamboo material has an extraordinary micro-structure: it has a high absorptive capacity after carbonization, and becomes even more effective after activation.[citation needed] Bamboo charcoal can be used to purify water and eliminate organic impurities and smells.[citation needed] Drinking water sterilized with chlorine can be treated with bamboo charcoal to remove residual chlorine and chlorides.[citation needed] In addition, a process involving bamboo charcoal has recently been developed in Taiwan using nanotechnology in combination with silver to produce a textile fibre.[citation needed] Thomas Edison's original light bulb had a carbonized bamboo filament.[citation needed]


Bamboo charcoal is known to have high porosity. Various impurities or foreign matter will be absorbed over the wide surface area of the charcoal. When air passes over, if the humidity is high, the charcoal will absorb the moisture and the air will be converted to dry air. If the air is too dry, then the charcoal will discharge its own moisture, thus adjusting the humidity in the air.[citation needed]

Bamboo vinegar or pyroligneous acid is extracted when making charcoal and is used for hundreds of treatments in almost all fields. This liquid contains 400 different chemical compounds and can be applied for many purposes including cosmetics, insecticides, deodorants, food processing, and agriculture.

There is some evidence that adding Bamboo charcoal or Bamboo vinegar to the diets of fish[1] or poultry[2] may increase their growth rates.

Popular culture[edit]

Bamboo charcoal is focused on as an ingredient, with many of its properties elaborated on, in the 29th episode of the anime Yakitate Japan where it is mixed into breads.

Burger King is now using Bamboo charcoal as an ingredient in its cheese for a new promotional burger in Japan. They are called The Kuro Pearl and Kuro Ninja burgers. [3]
