Wood Waste & Wood Pellet Analysis

Wood fuels in various forms are increasingly used for energy production.

Combustible materials range from sawmilling residues, like shavings or sawdust, to processed fuels, like wood pellets and wood chips.

The sale and purchase of wood fuels has highlighted the need for the seller and the purchaser of wood fuel to be confident with respect to the description and quality of the wood fuel sought or supplied.

The Bioenergy Association of New Zealand has developed guidelines for the classification of wood fuel. These guidelines provide a common methodology for classifying, specifying and determining the quality of traded wood fuel in New Zealand.

The classification of wood fuels is based on piece size, moisture content, ash content, bulk density and energy density. Veritec provides a range of tests to determine these values including:
  • Ash Content by Loss on Ignition
  • Calorific Value by Bomb Calorimeter analysis
  • Moisture Content
  • Fines Content by Sieve Analysis
