Biomass can also refer to our newest source of renewable energy and the best way to recycle biological matter. All plants, including those from the sea and other water bodies, are considered to be biomass.

Biomass is all of the matter which is organic, contains carbon, and has gone through photosynthesis and other processes. Biomass is mostly made up of plants which make use of the light from the sun to create energy .

Agro residues are used inefficiently causing extensive pollution to the environment.

Most of this biomass goes to waste by being dumped into landfills and even burned, which causes air pollution

The major residues are rice husk, coffee husk, coir pith, jute sticks, bagasse, groundnut shells, mustard stalks and cotton stalks.

Briquetting of the Agro waste & husk could mitigate these pollution problems while at the same time making use of this important industrial/domestic energy resource.

The material should be granular and uniform so that it can flow easily in bunkers and storage silos.

When compared to sawdust, agro-residues have a higher ash content, higher potash content and have poor flow characteristics.However, rice husk is an exceptional biomass.

It has good flow ability, normally available with 10 percent moisture and the ash contains fewer alkaline minerals, thereby it has a high ash sintering temperature.
