How to Briquette the Bio-Mass Waste?
Almost any biomass can be briquetted. Briquetting plants set so far in India are using Saw Dust, Bamboo dust, Bagasse, Cotton Stalk, Coffee husk, Groundnut Shell, Mustard Husk/Stalk, Pine Needles, Rice Husk, Sugar Mill Waste, Jute waste, Coir pith and other wastes & residues like Castor Shell, Red Gram Stalk, Tobacco stem, Tea Waste, Sander Dust, Tree Bark, Wild Grasses & Shrubs i.e. Any type of Agricultural waste or forestry waste can be also briquetted individually or in combination without using any binder.
- Raw material like Saw Dust Is screened and stalk (Forest & Agro waste) are crush or cut by Biomass Crusher Machine(Single Action) if the raw material size is larger than 25mm
- For using material of two or more types, It should be mixed in suitable form.
- If raw material has high moisture it should be reduced by Sun drying or using flash drier. Say if the moisture level is higher than 15% there would be a requirement of Biomass Dryer Machine.
- Biomass Crushing Machine is used to grind the material to get desired grain size.
- Raw material (desired grain size) is transported by pneumatic system to holding bins fixed over Briquetting Press.
- By Screw conveyor, material is discharged from bin to the press.
- Material is compressed by ram through taper bored die. By compression temperature is raised & lignin come to the surface and binds the material by its natural binder.
- Biomass Briquettes are formed in shape of log and it is automatically pushed through cooling line to the storage point.
Benefits of Bio-Mass Briquettes
Besides being cheaper alternative for conventional fuels, what makes its future brighter is easier availability of agro waste in ample quantity. With the rising awareness and demand for bio-mass briquettes, more and more industries across the sectors, are waking up to its benefits. More importantly, the various Governments too have realized its significance as cheaper and eco-friendly alternative to conventional source of fuels and energies. Governments are sparing no efforts to promote bio-mass briquettes by way of slew of tax benefits and financial incentives to boost the usage of bio-briquettes as alternate source of renewable energy. Let’s look at some distinguished benefits of bio-mass briquetting plants. The speedy viability of the project within a time frame of two years makes it more investment friendly.
- Rising demand due to rising cost of fossil fuel.
- Renewable source of fuel and energy
- Tax benefits and incentives
- Earlier viability
- Relaxed rules
- Pollution free because there is no sulfur content
- Easy mobility and transportation
- Contain high density
