Need to Measure Pulp Yield in Standing Trees?

for the past 10 years we have been developing Near Infra Red spectroscopic models to predict kraft pulp yield in small eucalypt wood samples... in an affordable manner.

What we offer

Forest Quality offers a range of products and services related to the assessment of wood properties in plantation forests.  Indicative prices are shown here.

Field Sampling for wood quality

We can undertake specialised field work, assisting with developing sampling plans and undertaking safe and thorough sampling programs. As experienced researchers, we understand the need for accurate and high quality data, and the associated record keeping.  As well as undertaking much of the analytical work, by undertaking the sampling as well, we can offer a seamless product minimising the number of inermediate steps the customr needs to organise.

Kraft Pulp Yield

Using a robust and well tested calibration, we can provide predictions of Kraft pulp yield (at kappa 18) on wood samples as small as 1 gram.  This can be done much more cheaply that conventional lab pulping (~AUD$18 - 50 per sample).  This includes grinding the sample into woodmeal; the cost difference being determined by the amount of sample that needs grinding.  A sample comprising large woodchips requires a larger grinder and more sample to get a suitably representative samples. Smaller samples based on drill frass or increment cores take less preparation.  (more on Kraft pulp yield)

Cellulose Content

As above, we can provide NIR-based prediction of (diglyme) cellulose content using a multi-site, multispecies calibration.  Alternatively or in combination we offer laboratory (diglyme) cellulose determinations of eucalypt samples.  A combination of the above provides a cost-effective approach using the laboratory data to provide a check of the NIR predictions.

Basic density

We can provide a measurement of basic density for solid wood or woodchip samples.  Either using us to collect cores from your plantation, or sending us cores you have collected, we can provide standard measures of basic wood density.  Or if you require more detailed analyses involving densitometry of SilviScan analyses, we can faciliate that and given our experience in the processing and analysis of SilviScan data, we can assist in its analysis and interpretation.  We have a NIR-based prediction of basic density for eucalypts that is close to being ready for commercial application.

Portable NIR calibration development

We can develop calibrations for portable NIR (such as the Polychromix Phazir) as required, for the prediction of KPY and cellulose content.  NIR can also be used for the measurement of a range of other plant properties such as foliar nitrogen.

Cabala modelling

Working closely with the developers of the process-based growth model Cabala, we can provide a technology transfer function that can help you utilise this state-of-the-art growth model in your forest operations.  Either to monitor the existing resource or explore a variety of "what if" scenarios to inform your decision making.

eCambium

Building from the work with Cabala, FQ has been extensively involved in the development and validation of the new process-based softwood quality model, eCambium.  This exciting new tool utiises daily variation in weather data to predict daily wood property variation in the generation of radial profiles of wood variability.  FQ can help you access this modellign capability to undertake an evaluation of how wood properties vary across your softwood forest estate.
