Briquettes
Briquettes
Biomass briquettes are 90 mm diameter in cylindrical shape made from agriculture waste or wood waste. Widely used in pharmaceutical, FMCG, Chemical, food processing and beverages etc, biomass briquette are cost effective and carbon neutral with minimal impact on environment. The usage of briquettes increases the farmer income and supports rural employment.

Notes
- Wood moisture percentage is higher compared to briquettes. In monsoon, wood moisture can be 45-50 %
- Wood size is inconsistent and Briquettes are uniform in size which allows better combustion
- Availability of wood is always a concern due to increasingly regulatory issue
Primarily briquettes are classified in 3 types.
Sawdust briquettes – These are made from sawmill wastage, wood chips and forest waste. Due to lowest amount of chlorine and ash percentage sawdust briquettes are widely used in small capacity boilers.

Agriculture waste briquettes – Agriculture waste briquettes are made from agriculture residue such as soyabean husk, cotton stalk, corn cob, mustard husk etc. Agriculture residue is available every year and suitable for large capacity boilers upto monthly consumption of 2500 per tons. Agriculture waste briquettes are consistently available through out the year.

Garden waste briquettes – Regular trimming of tree branches is necessary to maintain trees bigger cities municipalities are managing lacs of trees in their city limits. Managing the garden waste is increasingly becoming the bigger challenge for local municipalities as the dumping space is limited and already over limit. Converting this garden waste into briquetting not only solves the problem of space but also helps the environment to reduce the dependency on fossil fuels such as coal, wood, and furnace oil. The briquettes made from garden waste have similar properties of sawdust briquettes.
