Research topic: 5.3.2. Strategies for the sustainable and multipurpose utilisation of forest resources; the forestry-wood chain

Abstract:
An industrial tool for utilising more effectively forest raw material, destined for sawmills, will be developed and tested. The basis is a precise knowledge of wood properties from forest to end-producer achieved by identifying each log and board, allowing traceability. Wood data for one sawmill, acting as a model, will automatically be stored in a database, from harvesting of the log to cross-cutting at the end manufacturer. By analysing the data and utilising the knowledge on a European scale, and a number of sawmills having adopted the system, two distinct accomplishments will be met:

1) a more accurate judgement of log qualities already at the log sorting station means less wood raw material for producing a specific product;
2) means for a secure system to guarantee traceability through the forestry wood chain for specified products from forests managed in an environmentally sound manner.


Objectives:
Utilising wood raw material efficiently is a difficult problem, principally because of the great varia-tion in wood qualities and the fact that usually these are not sufficiently well known until the final board is on hand. Nor are the end manufacturers’ real needs sufficiently known at an early stage in the material chain. Therefore, more forest raw material than necessary is harvested in order to produce the required amounts of final products. Furthermore, by-products that are unwanted and difficult to sell are be produced. This leads to high costs for both manufacturer and consumer and to valuable forest material being harvested in a sub-optimal way. Several methods of judging log potential quality are, in practice, based on statistical comparison between bulks of logs and bulks of boards by matching distributions of properties. Sensors evaluating the wood material have become more and more elaborate, e.g. X-ray systems for inspecting logs and vision systems for grading boards. Since wood material quality is based on several individual, rather than a few bulk, properties and these properties are often dependent on each other in a complex way, the problem still exists. Therefore statistical comparison between bulk properties does not work. A method for handling detailed and sufficienty comprehensive data material, that can treat more than a few parameters in a sufficient way, is needed. The aim of LINESET is to facilitate a secure and automated system for industrial use to enhance forest raw material utilisation and guarantee its origin. The basis for this, and the main technical objective, is to develop an industrial prototype system for the automatic gathering of a detailed sawmill raw material database based individual logs and boards. The database will consist of data from the forest, the log sorting station, the saw line, the automatic green sorting station, the handling of stacked wood and, finally, the automatic cross cut saw at the end manufacturer. …
