Briquettes are compact blocks or cylinders made by compressing materials such as charcoal fines, wood chips, sawdust, or agricultural residues. They are commonly used as fuel sources for grilling, heating, and industrial processes. Charcoal briquettes are popular for outdoor cooking due to their uniform shape and consistent burn, while biomass briquettes offer an eco-friendly alternative using renewable resources. Briquettes are known for their efficiency and convenience, contributing to reduced waste and environmental benefits.
