bone is a popular product of the KAWA Agricultural
Ltd. Charred bone mainly consists of calcium phosphate and
carbon and is obtained from animal bones. The carbonization of
the bones was taken in kilns at temperatures up to 1000°C.
Depending on the application, the charred bones are processed
into a powdery or granulated product. It has four main uses:
first, it can be used for industry to make sugar, and secondly,
it is used as a resource for the active carbon, thirdly, it is
used as a special fertilizer, lastly, it can be used as an
additive of pigment.
Charred bone is not used in processing all cane sugars but its
use is very common. Since the bones are heated to a very high
temperature (to change them into carbon), there is a physical
change in its structure, leaving no actual bone particles. The
bone charcoal is used to filter the sugar; it does not become a
part of the sugar. After the sugar is refined, the remaining
charcoal dust is sold for use in animal feed.
As the resource for the active carbon, the active carbon which
is make of bone charcoal can cleaning water and absorb the
harmful materials of water even effectively. At present, it be
used in drinking water industry and treat with waste water from
carbon can raise the quality of farmers’ produce quickly and
effectively. For example, fruit will become sweeter and have
more flavour. Herbs, rice, and wheat will be of higher quality,
and it will raise the standard of green products such as tea and
vegetables, etc. Otherwise, it will benefit farmers by raising
the soils temperature one to five degrees to protect the produce
through the winter duration. Produce will also begin five to
fifteen days earlier than the regular starting date. Since it
can keep the soil moist. If it's mixed with other fertilizers it
can raise the effect about thirty percent. It helps in keeping
the soils nutrition and best growing condition by slowly
releasing its nutrition.
