Biomass Pellets

Biomass Pellets from Pakistan

Biomass pellets are manufactured by drying, grinding, and compressing biomass feedstock through a ring die or flat die pellet mill at pressures exceeding 2,000 kg/cm². The heat and pressure soften the natural lignin in the biomass, which acts as a binding agent, producing hard, dense, uniform cylindrical pellets with smooth surfaces. Pellets are the most refined and standardized form of solid biomass fuel, designed for automated feed systems in pellet boilers, stoves, and industrial burners. Pakistan’s diverse agricultural and wood waste streams provide a wide range of feedstock options for pellet manufacturing.

Available Feedstock Types

Sawdust/Wood Pellets

• Feedstock: Clean hardwood/softwood sawdust

• Calorific Value: 4,200-4,600 kcal/kg

• Ash: 0.5-2%

• Premium grade, closest to ENplus/DINplus standards, lowest ash and emissions

Rice Husk Pellets

• Feedstock: Rice husk from rice mills

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

• Ash: 14-18%

• Most abundant feedstock in Pakistan, lowest cost

Corn Cob Pellets

• Feedstock: Crushed corn cob

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

• Ash: 2-4%

• Good balance of calorific value, ash, and cost

Bagasse Pellets

• Feedstock: Sugarcane bagasse

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

• Ash: 2-5%

• Seasonal feedstock (October-March milling season), stored year-round

Mixed Agri-Waste Pellets

• Feedstock: Blend of sawdust, rice husk, corn cob, bagasse, wheat straw

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

• Ash: 3-10%

• Most cost-effective, year-round availability

Industrial Uses

• Industrial boiler fuel: Biomass pellets are the preferred solid biomass fuel for modern automated boiler systems. Their uniform size and density allow precise feed rate control, consistent combustion, and automated ash removal. Used in textile mills, food processing plants, paper mills, chemical factories, and manufacturing operations replacing coal and furnace oil

• Power generation (co-firing and dedicated): Pellets are co-fired with coal in thermal power plants or used as standalone fuel in dedicated biomass power stations. Major European and Asian utilities import biomass pellets to meet renewable energy mandates

• District heating: Pellets fuel district heating boilers in residential and commercial complexes, universities, hospitals, and municipal heating systems

• Residential heating: 6 mm pellets are used in residential pellet stoves and pellet boilers for home heating in Europe, North America, and East Asia

• Cement and lime kiln fuel: Pellets serve as alternative fuel in cement plants and lime kilns, reducing fossil fuel dependency and qualifying for emissions reduction credits

• Gasification: Uniform pellet size and density make them ideal feedstock for biomass gasifiers producing syngas for power generation and industrial heating

• Steam generation: Clean-burning pellets generate process steam for food processing, pharmaceutical, and chemical manufacturing where fuel quality and emissions control are critical

• Carbon credit programs: Biomass pellet production and use qualifies for carbon credits under CDM, Gold Standard, and voluntary carbon market programs

Quality Assurance

Each lot is tested for calorific value, moisture, ash content, volatile matter, fixed carbon, sulphur, chlorine, mechanical durability, bulk density, fines content, and pellet dimensions. Testing follows EN ISO 17225-6 (non-wood pellets) or EN ISO 17225-2 (wood pellets) standards where applicable. Pre-shipment samples are provided for buyer evaluation. Pellets are sourced from verified manufacturing plants with consistent feedstock drying, grinding, and pelletizing quality.
