A review on various types of densification/briquetting technologies of biomass residues

Abstract

Abstract The growing development, industrialization and population is the main reason of the increment in the global power demand around the world. The conventional power resources are limited and not eco-friendly as well as diminished in the future. Now, every country is move towards the more utilization of renewable energy resources. The biomass renewable energy source is one of them. The biomass residues material can be utilized for the production of power and also overcome the problem of decomposition of agricultural wastes and other wastes products by conversion into solid biomass fuels. The conversion of scattered agricultural residues/wastes into the useful product (biomass fuel) through the technology known as densification. The densification process supports the more utilization of renewable source and clean energy demands. The environmental challenges related with burning of biomass residues in the open field can be minimized by the densification of biomass residues. The densification is the process of compaction or densifying the biomass residues or waste through the application of various pressure levels. The challenges associated with handling, storage and transportation of biomass residues can also be minimize by densification technology. Briquettes and pellets are the end product of densification applications. The various types of densification pressure application and comparison have been discussed in the paper.
