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.
Bamboo charcoal has a long history in China and has been documented as early as 1486 during the Ming dynasty in Chuzhou Fu Zhi. Later, it was also mentioned in the Qing dynasty during the reigns of the Kangxi, Qianlong and Guangxu emperors.
== Production ==
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.
