Raw material intake
Incoming plantation residues and timber are reviewed before entering the production process.
Quality Control
Controlled parameters from raw material to finished pellet
Quality begins with the incoming feedstock and continues through drying, pelletizing, screening, and final product checks.
The control approach
What Yinuoda checks across the process
Each stage affects the final fuel. Managing the full process in-house makes it possible to monitor and correct variation before it reaches the finished product.
Moisture management
Drying is controlled because excess moisture reduces useful heat and creates handling issues.
Particle profile
Crushing and grinding prepare a consistent particle size before pellet formation.
Pellet density
Compression is managed to produce durable, dense pellets that hold together through handling.
Cooling and screening
Finished pellets are cooled and screened to remove excess fines before storage and packaging.
Batch documentation
Specification and origin details can be reviewed and confirmed for the destination market.

Certification support
Market-specific documentation and standards
Different regions expect different evidence. Yinuoda can discuss ENplus, FSC, and FIT/FIP-aligned certification support based on the destination market and buyer requirements.
For a serious procurement evaluation, ask for the exact documentation set your market requires: specification sheet, origin statement, sampling evidence, and any standard-specific data.
