Abstract
Programme group Wood and lignocellulose composites consists of researchers employed at the Department of Wood science and technology at Biotechnical Faculty, University of Ljubljana. The main purpose of our group is to understand wood, and to use it for products with as high added value as possible. Wood is the only renewable raw material available in Slovenia. It is CO2-neutral; even more during wood formation carbon dioxide is absorbed and thereby contributes to tackling climate changes.   Work in our program is organized in six working groups. The first group examines factors that influence the wood formation, response of the trees to stress and so on. This knowledge is important for reconstruction of the past climate. Even more, we can use those techniques to date the old buildings and wooden constructions. Nevertheless, these data were used for dating of the oldest wheal in the world.   The second working group is focusing durability of the wood. Wood is as natural material subjected to biotic and abiotic factors of decomposition. In nature, these processes are desirable, but when the wood is used for commercial purposes these processes needs to be slow down as much as possible. Nowadays, nonbiocidal techniques for wood protection, like wood modification and treatment of wood with water repellants, are becoming more and more important. Recently very interesting nano based surface coatings were developed.   The purpose of the third group is to overcome issues related to limited dimensions of wood. Therefore, we want to apply different engineering approaches to transform wood and glue it in limitless sized composites that can be used for attractive and on the other hand safe constructions. We strongly believe, that one of the benefits of our work is fact that importance, and market share of wood construction is increasing. Wood composites are not only useful for construction purposes. We used wood based composites every day, since most furniture is made of composite plates.   The fourth working group deals mainly with the innovative use of wood. In this group we want to obtain as much as possible of commercially attractive chemicals from wood. Even a simple extraction can be applied to obtain commercially interesting chemicals from wood, that are useful as nutritional supplements, supplements for whisky, red wine, etc. Considerable part of research is devoted to nanofibrilated cellulose, recently.   However, developing of the new solutions, techniques materials is senseless if they do not have market potential. This task is related to the fifth working group. In addition, they deal with the organizational and IT solutions in the wood processing industry. The task of the sixhth working group is to organize and promote the work in the frame of this programe.
Significance for science
With proposed program basic knowledge in wood science will be broaden, and new basis for continuous work on this field will be prepared.   Results will be published in leading journals from the field of wood science and thereof contribute to the human knowledge about wood. Due to interdisciplinary nature, we will publish in other fields as well. Certain part will be published in Slovenian language, to ensure transfer to experts and to ensure development of Slovenian terminology.   Publications will enable programme group to continue editing of some Journals or to remain their position as members of editorial board International biodegradation and biodeterioaration (Pohleven), Wood resarch (Humar), Wood industry (Gorišek, Petrič, Čufar), Dynamic relationships management journal (Kropivšek), Journal of adhesion science and technology (Petrič, Šernek), Acta silvae et ligni (Oven, Medved), Les (Oven, Petrič, Šernek, Humar), The open environmental engineering journal (Humar).   Studying the interactions between wood and chemicals used will broaden knowledge of the chemistry of preservative solutions and wood, as well as their interactions.   The development and/or optimisation of the experimental and instrumental methods will significantly enhance the ability to use several methods in science of lignocellulosic materials.   Studies of fungal colonization of wood treated with various biocidal and non-biocidal solutions will improve understanding of fungal decay and fungal ecology.   Novel preparation methods for coated nanoparticles for coatings will be developed. Nanoparticle deposition processes on wood will be researched and optimised. Efficient colourless wood protective systems will be examined. Liquefied wood based coatings will be upgraded with inclusion of nanoparticles.   New knowledge in the field of adhesives, lignocellulosic composites and building with wood. Knowledge about techniques for bonding, joining and manufacturing of composites. Understanding adhesion when bonding lignocellulosic materials with other materials, and in case when the new adhesives are used.   Investigations of NFC and extractives are opening completely new and highly actual scientific fields, which enable publication of original results in peer-review journals. Research is designed in the way, that the final goal is application of products. These will very likely result in patenting of findings and inventions.   Training and education in the wood companies provide employee competencies to perform the work, which in turn leads to their increased motivation and greater efficiency and quality of the work. This is a prerequisite for innovation in the development of the companies, the search for new and better solutions and increase competitiveness, which opens opportunities for further expansion and employment.   Research in the framework of the proposed programme will strengthen scientific international and national collaboration in the field of wood science.
Significance for the country
The major part of Slovenian culture-historical heritage is made or based on wood. This heritage is endangered deu to insufficient maintaining and several biotic and abiotic decay factors. In order to keep this heritage for latecomers, all knowledge needs to be used. Significant part of this knowledge was and will be developed in the frame if this programme. Improved measures to reduce damage in Slovenian forests due to storms, and more optimal use of wood. Development of the moisture based indicators will enable prediction of service life and maintenance intervals for selected materials, which will enable use of these materials for purposes for which they have not previously been used, due to the lack of knowledge. Predictive service life data will be useful for other companies involved in wooden construction. This will increase the consumption of domestic wood, which does not require much energy for machining, and will decrease dependency on imported material and energy in Slovenia. Programme of innovative producers of wood coatings and products will be wider (e.g. Chemcolor, Silvaprodukt). Producers with relevant production conditions (e.g. Tanin) will be able to start with a production of sustainable liquefied wood based coatings (competitiveness, new jobs, sustainable development of Slovenian regions. New knowledge will enrich the academic study programmes. Proposed research will result in scientific excellence and in development of new industries, which will be grounded on innovative and high value added products from biomass. This approach guarantees development of entire forest-wood-paper chain. New technologies of joining and bonding will enable the production of new lignocellulosic composites products, elements and complete solutions in the field of sustainable construction. New knowledge will allow us to be able to develop new technologies for new products with which it will be possible to penetrate new markets; to set up new businesses; provide jobs and development; reduce the environmental burden of toxic substances; reduce the risks and diseases at work, as well as economically rational utilization of a variety of natural residues from the manufacture and recycling of existing lignocellulose composites. The thermal insulation of products and buildings will be improved, what will result in more sustainable consumption of energy. There are two cubic meters of carbon dioxide stored in each cubic meter of wood. If more wood will be utilised for wooden products or constructions, more CO2 will be stored in wood. Training and education in the wood companies provide employee competencies to perform the work, which in turn leads to their increased motivation and greater efficiency and quality of the work. This is a prerequisite for innovation in the development of the companies (and sector), the search for new and better solutions and increase competitiveness, which opens opportunities for further expansion and employment. Wood is an important source for infrastructure, too (poles, railway ties, bridges, noise barriers,...). This infrastructure requires reliable protection. The collected data will enable us to predict maintenance intervals and replacement times more accurately.
