Reed Pellets Untapped Potential

Although reeds is classified as grass types of entering grade 3 in biomass fuels due to its properties. But if the amount abundant and has not been utilized, it becomes a great potential to be processed into  pellets fuel. Thousands hectares of Reed such as in Borneo, Indonesia can be further processed for the production of pellets.

Due to high content of silica which makes abrasives that are not friendly to the metal with the high compression in densification that is needed special metal material that is more resistant for the ring die and roller. It also needed a thicker die to process material type grasses to increase compression (friction), the contribution to deliberate more lignin and finally to improve the quality product. The low of lignin content on the type of biomass also make necessary modifications in the process in pelletiser . The thickness of the die, pressing time, pressing temperature and pressure, will help improve the quality of the reed pellets without the need for additional adhesive. Mix with other ingredients (mix the material) that have greater lignin content such as sawdust will also improve the quality of the Reed pellets. The table below prosesntase a number of chemical compounds in the biomass.

Pellet production process of these grasses will generally produce more dust because its small  percentage of the lignin that need extra treatment in  the dust elimination system. Process operating conditions in pelletiser also affect the percentage of dust generated.

While the advantages of this material is that grass only has a low water content so that the drying phase can be minimized. In general, also the energy required for the production of pellets of the type of grass is lower than the sawdust material, woodchip and logs.

Market opportunities for grass type pellets is also wide open. Huge energy demand for various industries is an attractive market opportunities. The fuel quality requirements are not so high in a number of industries also make grass pellets well accepted, for example, for ceramic industries, bricks and so on.

5 The Largest Wood Pellets Producers Today

References are needed to make something no less quality or even better, as well as for a wood pellet production facility. Indonesia with extensive land available,fertile and tropical climate needs to get complete and qualified reference especially on wood pellet production so that they can optimize its potency. Diversification of energy is also desperately needed by Indonesia so that it has strong resilience and energy sovereignty, especially with its current condition which has become a net importer of petroleum, even projected in the range of approximately 10 years future Indonesia's oil will be exhausted. The following description of the 5 largest wood pellet plant today can be used as a reference.
Enviva was established in 2004, currently Enviva operates 7 wood pellet plants with total production of more than 3 million tons / year. Some of its wood pellet production is exported to the UK and Europe. A number of ports are used For shipment or export of wood pellet, ie po…

Carbon Positive, Carbon Carbon Neutral or Negative?

Greenhouse gases from burning fossilfuels have caused the Earth's temperature to rise. Increasing the temperature of the earth or global warming causing numerous disasters due to climate change in a number of places on earth. When greenhouse gases not controlled then the result of damage to the environment of the earth will be more severe. Therefore, efforts were made to reduce greenhouse gases as the cause of environmental problems. In general, there are four common scenarios to prevent the global warming effect of CO2 in the atmosphere gradually, namely: 1.increasing the efficiency so the fossil fuel consumption decreases, 2.mix of renewable fuels with fossil fuels so that fossil fuel consumption has also decreased, 3.substitution of fossil fuels with renewable fuels 4.and the absorption of CO2 in the atmosphere so that the concentration of greenhouse gases can be reduced. Here are some basic terms related to the above problems. Based on the origin and the effect that CO2 in the atmo…
