Biomass Briquettes

Biomass Briquettes from Pakistan

Biomass briquettes are manufactured by compressing dried agricultural waste or wood residues under high pressure (1,000-1,500 kg/cm²) and elevated temperature in mechanical or hydraulic briquetting presses. The heat generated during compression softens the natural lignin in the biomass, which acts as a binding agent, producing a dense, solid fuel block without any added chemicals or adhesives. The result is a clean-burning, high-density renewable fuel with consistent calorific value, low moisture, and low ash content, suitable for replacing coal, firewood, and other fossil fuels in industrial heating applications.

Available Feedstock Types

Sawdust Briquettes

• Feedstock: Clean hardwood/softwood sawdust

• Calorific Value: 4,200-4,500 kcal/kg

• Ash: 1-3%

• Premium grade, highest calorific value, lowest ash

Rice Husk Briquettes

• Feedstock: Rice husk from rice mills

• Calorific Value: 3,200-3,600 kcal/kg

• Ash: 15-18%

• Most abundant feedstock, lower cost

Corn Cob Briquettes

• Feedstock: Crushed corn cob

• Calorific Value: 3,800-4,200 kcal/kg

• Ash: 2-4%

• Good balance of calorific value and cost

Bagasse Briquettes

• Feedstock: Sugarcane bagasse

• Calorific Value: 3,600-4,000 kcal/kg

• Ash: 2-5%

• Seasonal availability (October-March milling season)

Mixed Agri-Waste Briquettes

• Feedstock: Blend of sawdust, corn cob, bagasse, wheat straw, cotton stalk

• Calorific Value: 3,500-4,000 kcal/kg

• Ash: 3-8%

• Most cost-effective, year-round availability

Industrial Uses

• Industrial boiler fuel: Biomass briquettes are burned in industrial boilers to generate process steam for textile mills, food processing plants, chemical factories, paper mills, and other manufacturing operations. They replace coal, firewood, and furnace oil with a cleaner, renewable alternative

• Brick kiln fuel: Briquettes are used as a fuel replacement for coal in brick kilns, significantly reducing sulphur emissions and carbon footprint while maintaining kiln temperatures

• Power generation: Biomass briquettes are co-fired with coal or used as standalone fuel in biomass power plants for electricity generation

• Cement and lime kiln fuel: Used as supplementary fuel in cement plants and lime kilns as part of alternative fuel programs to reduce fossil fuel consumption

• Institutional heating: Briquettes are used in heating boilers for hospitals, schools, hotels, and commercial buildings in cold regions

• Gasification: Biomass briquettes are used as feedstock in biomass gasifiers to produce producer gas for engine-driven power generation and thermal applications

• BBQ and charcoal replacement: High-quality sawdust briquettes are used as a clean-burning alternative to charcoal for barbecue, grilling, and outdoor cooking

• Carbon credit projects: Biomass briquette production and use qualifies for carbon credits under CDM and voluntary carbon market programs by displacing fossil fuels

Quality Assurance

Each lot is tested for calorific value, moisture, ash content, volatile matter, fixed carbon, sulphur, and density. Pre-shipment samples are provided for buyer evaluation. Briquettes are sourced from verified manufacturing plants with consistent feedstock supply, drying, and compression quality.
