During a field trip organized by the Department of Tropical Agriculture and International Cooperation at NPUST, we visited a bamboo charcoal factory at Hualien County, located in the northern region of Taiwan. In this report I wanted to show the production of bamboo charcoal and the different products they offer.

This bamboo charcoal factory operates in the countryside of Hualien.
Bamboo charcoal is prepared for different purposes and for different products.

Ovens are feed by gas, they count with 4 ovens that operate for 3 days to reach the desired temperature.

Gas is fed by a small compressor that is connected to the gas pipe, fire is started and is introduced to the oven.
Computers control the temperature in the ovens.
After 3 days, the oven can reach a temperature of 1100 C, which is the desirable temperature to produce their charcoal. Once the oven is in that temperature, the computers will stop the fire.

During the bamboo to charcoal process the liquid tars are separated and kept in containers for later treatment.
Tars are kept for about six months; they separate the heavier tars from the most soluble ones. The liquids are treated to obtain different products.

Bamboo Charcoal ovens have a chimney that conducts the smoke produced during the process through a pipe and has an exit to an open area. A small fan, placed at the starting point of the pipe, pushes the smoke out.  In order to reduce the smoke produced, gas is adapted to the exit of the chimney which will burn the smoke transforming it in to gas.

Bamboo Charcoal is used in water filtration and has a small demonstration area where electrical conductivity can be tested by the visitors.

I wanted to buy a sample of their product, to use at the lab for different tests, but I found that the price for a kilogram of their product was 1000 NT (30 USD), also was not enough to perform a field test and apply it into soil for plant growth with such a small amount.

I bought a small sample of bamboo biochar to test it at out laboratory, from that small sample we can obtain pH, EC, FTIR, SEM, etc. (Cost 4 USD).

The Bamboo Charcoal Shop offers to the public different products fabricated from bamboo charcoal; among them we can find clothes, disinfectants, repellents, ice cream, pudding, jewelry, etc.

  1. Activated charcoal is very mild on the colon and does not interfere with the natural mucus lining of the intestines. carbon charcoal

  2. Good. Very informative and useful to highlight the potential of value addition potential of bamboo & other agricultural produces by turning into bio char- charcoal from organic produces . Great opportunity for collaboration and diversification in the context of climate action. Congrats&sharing.
