Why biomass—and why details matter
Biomass is a strategic fuel for power plants and industrial boilers, but variability can be costly. Moisture, ash content, calorific value, and size distribution directly affect efficiency. A robust procurement and QC plan is essential.
Common biomass products
- PKS (Palm Kernel Shell): widely used; check for contaminants and size uniformity.
- Wood chips: species mix, chip size, bark content.
- Wood pellets: diameter/length, durability, fines, moisture, ash, and energy value.
- Agricultural residues (e.g., empty fruit bunch processed, rice husk): confirm preparation and handling standards.
Key specifications to define
- Moisture content (MC): affects energy yield and storage stability.
- Ash content & composition: influences slagging/soot; some boilers require low-ash fuel.
- Calorific value: specify as GCV/NCV and the method used.
- Size distribution: mm range for chips/PKS; pellet diameter/length and fines %.
- Bulk density: important for transport planning.
- Foreign matter: allowable limits and rejection criteria.
Quality control workflow
- Pre-shipment sampling with agreed method and sample size.
- Lab analysis (MC, ash, GCV/NCV, size, fines).
- Photographic evidence of stockpiles, loading, and sealing.
- Independent inspection on request, with sealed counter-samples.
- Digital reporting: results, timestamps, and chain of custody stored centrally.
Logistics & storage
- Packaging: bulk in holds/containers, super sacks, or bags; pellets need moisture protection.
- Handling: minimize breakage/fines; pellets require careful loading/unloading.
- Incoterms: FOB/CIF/CFR are common; define who handles insurance and customs.
- Storage: ventilation and moisture control; clearly assign responsibility post-delivery.
Compliance & documentation
Prepare a document pack: invoice, packing list, B/L, COO, analysis/inspection reports, and insurance where applicable. Keep a reconciliation sheet linking results to lot numbers.

FAQs
1) Can you guarantee a specific calorific value?
We align on spec targets and tolerances, then verify via lab analysis and optional third-party inspection.
2) Do you provide moisture-controlled packaging for pellets?
Yes, we can arrange moisture protection and loading methods that minimize fines.
3) What volumes can you handle?
From trial lots to sustained monthly programs—subject to origin capacity and logistics.
4) Can shipments mix biomass types?
We advise single-type lots for traceability and uniform performance; mixing is case-by-case.
5) Do you support sustainability or origin declarations?
Where available, we’ll outline documentation and verification options.
