The process of briquettes consists of following steps: 
- Gathering biomass waste material
- Crushing
- Compressing to form briquette
- Drying the briquettes
Advantages of Briquettes
- Briquette is replaces the usage of conventional type of fuels
- Considered as best renewable source of fuel and energy
- It causes negligible pollution
- Has great thermal calorific value
- It uses bio-waste to produce briquette thus it is very cheap
- They are easy to store, handle and transport from one place to another
- Useful in many applications of domestic, commercial and industrial area
- Low moisture content results in higher burning efficiency
