THE MJ RICE HUSK
ZERO-WASTE TECHNOLOGY :
The MJ rice
husk zero-waste technology is a management approach to full
utilization of rice husk and its by-products. In this
approach, rice husk is completely utilized (i.e., from raw
rice husk to its by-products) not leaving a single particle
that stays unused. This approach was developed after
exploiting all possible technologies in utilizing rice husk
and its by-products that benefit the human race, both at the
domestic and at the industry sectors.
MAXIMUM UTILIZATION OF
RICE HUSK AND ITS BY-PRODUCTS :
Rice husk is
converted to energy and the resulting residues are further
utilized for agricultural and industrial uses. Gasification
process, which is the most convenient and efficient way of
extracting the energy available in the material, is
employed. The by-products from rice husks are further
utilized as secondary energy sources in either solid or
liquid form of fuel. The ash remaining after all the
volatile matters and carbon are removed from rice husk is
utilized as primary or secondary materials for the
production of low-cost rural housing construction material
and for the improvement of the condition of the soil. More
importantly, ash can be used for industry application such
as for the manufacture of cement and of glass. By injecting
steam into the burning gas from rice husk, the available
energy is increased by about 20 to 30% and a cleaner gas is
derived.
The following
are the advantages and/or applications of this technology:
-
The energy
from rice husk is conveniently and efficiently extracted
producing gaseous fuel;
-
The gas
from rice husk can be used as fuel for various heating
applications such as domestic cooking, agro-industrial
heating and processing, and as fuel for firing oven,
kiln, and boilers;
-
It can also
be used as fuel to replace gasoline, diesel, etc. for
running internal combustion engine to produce mechanical
as well as electrical power;
-
During the
process of gasification, the bio-oil or the smoke
vinegar can be extracted from the gas stream to produce
a clean gaseous fuel and the by-product, which is char,
can be processed further to produce biocoal fuel or it
can be used as a soil amendment element to improve crop
production;
-
After
extracting all the volatile matters and carbon from rice
husks, the ash can be further utilized in producing a
low-cost building material for rural housing and
agricultural infrastructures;
-
Processing
rice husk ash further will produce amorphous silica,
which is an excellent replacement to the high-priced
silica element needed in cement and in glass
manufacturing industries.
