ABSTRACT
Biomass can be converted to efficient biofuels by various methods. The conversion methods are broadly divided in to four categories such as Physical, Biochemical, Thermochemical and Agrochemical. In physical method of conversion, densification of biomass into solid compact briquettes is done. The process of biomass compaction into a advanced density product than the original raw material is known as densification or briquetting. Briquetting of biomass is a traditional technology. In this method of briquetting, high pressure is applied to a particle mass with or without binder to alter it into a compressed form. The obtained products could be in a hollow cylinderical shape or in a geometrical solid form known as briquettes (the compressed fuels) similar to coal has ability to replace solid conventional fuels, even diesel to meet the various regions’ local needs. The densification process is eco-friendly and manages to control environmental pollution as there is no harmful and toxic emission of gases during combustion.
