Raw Materials for Biomass Briquette

Biomass briquettes are made from a variety of raw materials that are generally byproducts from agricultural or forestry operations. Here are some common raw materials used to produce biomass briquettes:

  • Sawdust: A byproduct from woodworking operations such as sawmills and furniture manufacturing.
  • Agricultural residues: Includes straw, husks, shells, and stalks from crops like rice, corn, and wheat.
  • Paper waste: Recycled paper that can be processed and used as a component in briquettes.
  • Leaves and yard debris: Dry leaves, grass clippings, and other green waste can be compressed into briquettes.
  • Wood chips and shavings: Small pieces of wood and shavings that are too small for other uses.
  • Peat: Decomposed organic material often used in gardening, which can also be compacted into briquettes.
  • Coffee husks: A byproduct of coffee production, these can be converted into a fuel source.
  • Coconut shells: Hard shells of coconuts are a substantial biomass resource in tropical regions.
  • Cotton stalks: Leftover stalks from cotton harvesting can be used in briquette production.
  • Bagasse: The fibrous residue left after extracting juice from sugarcane, commonly used for making briquettes, especially in sugar-producing countries.
These materials are typically dried and then compressed without the use of binders, using the natural lignin within the biomass to act as a binder during the pressing process, resulting in solid, dense briquettes.
