The title of the
utilization of renewable energy and environmentally friendly, has a bustling
decorate various print and electronic media at this time. Availability
of fossil energy are dwindling and unsustainable become a major driving force
to give attention to renewable energy. Over time by increasing energy
needs, it is inevitable renewable energy will become a mandatory requirement in
time. Lignocellulose biomass such as woody is an abundant source that is
easily obtainable as well as easily cultivated to the sustainability of their
supply. Facts about the low use of renewable energy such as biomass can
be viewed from a number of factors, including environmental awareness is still
low, including letting productive lands without results even tend to occur
desertification, lack of awareness of self or sovereign in the energy sector as
one of the vital needs, the lack of or the lack of mastery of technology for
renewable energy production and utilization resulting in the inability to see
the potential of biomass is very large in tropical areas like our country.
Wood briquette is
a product compaction (densification) biomass. Compared to wood pellets,
wood briquette is also less popular and production not as much wood pellets.
Technically wood briquette quality is not inferior to wood pellets, because in
general the density of wood briquette is higher than wood pellets. In
addition to the surface of wood briquette also occurr partial carbonized that
makes it easy ignited. The large size of wood briquette makes it not easy
to flow or be poured as well as wood pellets, which could be a factor that
makes wood briquette less desirable. Basically wood briquette similar to
wooden sticks as firewood used for cooking, with a density of approximately 2
times the hardwood so to burn is also not a difficult thing. Some
furnaces are accustomed to using firewood will easily adjust to the wood
briquette.
Wood briquette is also less publicity than wood pellets, so wood
pellets usually more popular. The use of wood pellets for various
industries also have started to bloom as in the tea industry for the process of
withering and drying the tea leaves themselves. The content of
anthraquinone also be very low when using wood pellets as fuel for the process
so that it can be accepted by European market in particular. Characteristics
of wood pellets which can bulk this is what makes many selected.
Basically wood
briquette also has the same functionality, only slight modifications to the
furnace may be needed due to the large size. Resume biobriquette or wood
briquette application can be read here. The use of wood briquette and
mastery of production technology should be easier to do. Wood briquette
has a longer produced in various regions in Indonesia, more than 20 years ago
as an intermediate product in the production of sawdust charcoal briquette.
Fabrication or manufacture of equipment for wood briquette production also has
a 100% have been able to be produced in the country, in contrast to wood
pellets that most of its production equipment is still imported.
In addition to
the woody biomass waste, plantation waste such as empty fruit bunches of palm oil
is also good potential compacted into pellets or briquettes. In the palm
oil mill the energy needs both heat and electricity in general have been able
to be satisfied by the mesocarp fiber and palm kernel shell. Palm Kernel
shell even many left, and they can be sold because it can be directly used for
fuel and could bulk as well as wood pellets. Large palm oil industry
does not only produce crude palm oil or CPO (crude palm oil) but with a range
of derivative products or purification/refinery to increase the added value of
the CPO will need a lot of energy for the production process. Picture
below about purification scheme (refinery) CPO to produce a wide range of
derivative products.
EFB briquettes as
a source of energy that CPO refinery. A palm oil mill operations are
efficient and zero waste with optimal utilization of wastes for energy
resources could have done well with the above-mentioned mechanism. The
ash from burning briquettes that are rich in potassium (K) also can be levied
which will be used for organic fertilizer on palm plantations.
