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.
