Project

Detection of wood species and decay with NIR hyperspectral imaging

It is important to detect the defects in timber to ensure the correct assessment of delivered timber. It is difficult to detect and correctly estimate the proportion of decay within the timber and thus there is a big risk of defec…
Project

High-resolution characterization of aspen greenhouse samples

It has traditionally been difficult to analyze small diameter greenhouse samples with SilviScan and an imaging near-infrared (NIR) camera. The aim of this project was to develop effective methods for the high-resolution analysis o…

Papermaking variability

Everyone benefits from even production and less waste. However, some connections between variations in the process and undesirable properties in the product could be difficult to find with everyday working methods. RISE performs c…

High-resolution Wood characterisation

High-resolution wood characterization is mostly done in tree breeding and genetic studies in collaboration with researchers from academic and research institutes. The samples analysed can be drill cores or cross-cut discs from wel…
Test & demo

Testbed for wood and fibre properties

The laboratory has world-unique instruments for efficient analysis of a large number of properties of wood and fibres important for industry and research. The instruments can also contribute to projects where effects of forest man…
