Sawdust

Sawdust from Pakistan

Sawdust is a fine particulate wood residue produced as a byproduct of timber sawing, planing, routing, and sanding operations. Pakistan’s extensive timber processing and furniture manufacturing industry generates large volumes of sawdust from both hardwood species (sheesham/rosewood, mango, neem, kikar/acacia) and softwood species (deodar, pine, chir). The sawdust is collected, screened, dried, and packed at source for biomass, industrial, and agricultural end-uses.

Specifications

• Material: Natural wood sawdust

• Wood Species: Mixed hardwood, mixed softwood, or single species (on request)

• Particle Size: 0.5-5 mm (typical)

• Moisture: 8-15% (air-dried), < 10% (kiln-dried)

• Calorific Value: 3,800-4,200 kcal/kg (at < 12% moisture)

• Ash: 0.5-2%

• Volatile Matter: 75-85%

• Fixed Carbon: 12-18%

• Bulk Density: 150-250 kg/m³ (loose), 350-500 kg/m³ (compressed)

• Colour: Light tan to golden (species-dependent)

• Contaminants: Free from paint, varnish, chemicals, nails, and treated wood

Available Forms

• Loose sawdust (air-dried or kiln-dried)

• Compressed bales (30-50 kg each)

• Bagged sawdust (25 kg or 50 kg PP bags)

• Jumbo bags (500 kg or 1 MT)

Industrial Uses

• Biomass fuel: Sawdust is burned directly in industrial boilers, brick kilns, and biomass power plants as a renewable solid fuel. Low ash content and high volatile matter ensure clean, efficient combustion. Calorific value of 3,800-4,200 kcal/kg at < 12% moisture

• Briquette and pellet manufacturing: Sawdust is the primary raw material for producing biomass briquettes and wood pellets through compression under heat and pressure. Briquettes and pellets are denser, easier to handle, and have higher calorific value per unit volume than loose sawdust

• Particle board and MDF: Sawdust and wood chips are pressed with adhesive resins to produce particle board (chipboard) and medium-density fibreboard (MDF) for furniture, cabinetry, and interior construction

• Animal bedding: Clean, kiln-dried sawdust is used as absorbent bedding for horses, cattle, poultry, and small animals. It provides cushioning, absorbs moisture and ammonia, and is biodegradable and compostable

• Composting and soil amendment: Sawdust is blended with nitrogen-rich green waste to produce compost, mulch, and growing media for horticulture, landscaping, and organic farming

• Mushroom cultivation: Pasteurized sawdust is a standard substrate for shiitake, oyster, and specialty mushroom cultivation

• Industrial absorbent: Sawdust absorbs oil, grease, coolant, and chemical spills in workshops, factories, garages, and warehouses

• Smoking and flavouring: Food-grade hardwood sawdust (sheesham, mango, neem) is used in meat smoking, cheese smoking, and barbecue flavouring

• Insulation and packaging: Sawdust is used as a loose-fill insulation material and as protective packaging filler for fragile items during shipping

Quality Assurance

Each lot is tested for moisture, calorific value, ash content, particle size, and absence of contaminants (paint, chemicals, treated wood, nails, metal). Clean sourcing from verified timber mills ensures consistent quality. Pre-shipment samples are provided for buyer evaluation. Phytosanitary certification and fumigation are arranged as per destination country requirements.
