It should be remembered that in the Congo Basin, investments in new wood processing plants or in the extension of existing ones are still very limited. In addition, the 3 wood products exported from this region are mainly sawn timber, veneers, and plywood. It should be noted that despite some timid existing opportunities, some companies operating in the Congo Basin are struggling to invest in wood processing and therefore do not effectively contribute to the development of national and sub-regional economies. To better capitalize on these opportunities, it is important to create a business environment conducive to new investments in advanced wood processing. Ultimately, this study made it possible to assimilate the techniques and processes of obtaining veneers and plywood successfully through the technology of the machines developed, with the application of our theoretical knowledge in order to gain experience of professionally enhanced intellectual capacities. The plywood production is fixed at 6,651 m3; 8,452 m3 respectively in 2011 and 2012 showing a gradual increase in the order of 1,801 m3 due to strong demand from the local market. With regard to the annual volume of veneers obtained, the yield of veneers and plywood obtained were the following R1 ≈ 44% and R2 ≈ 30%. Exports of peeled veneers recorded a drop of 8.20% in volume, reaching 25,893.244 m3 in 2019 against 28,206.341 in 2018. However, peeled veneers each ranked 4th, in order reached 25,893.244 m3 or 2.60%. Okoumé, with 391,030,067 m3, or 39.31% of the total volume, was the main forest species among the various exported products, out of more than sixty exported concerned. Rappelons que dans le Bassin du Congo, les investissements dans les nouvelles usines de transformation du bois ou dans l’extension de celles existantes restent encore très limités. En outre, les 3 produits de bois exportés de cette région, sont majoritairement les bois sciés, les placages et les contreplaqués. Soulignons qu´en dépit de quelques timides opportunités existantes, certaines entreprises opérant  dans le Bassin du Congo peinent à investir dans la transformation du bois et de ce fait, ne contribuent pas efficacement au développement des économies nationales et sous-régionales. Pour mieux capitaliser ces opportunités, il s´avère important de créer un environnement d´affaires propice aux nouveaux investissements dans la transformation poussée du bois.  En effet depuis l’année 2000, le Congo  s’était  doté de la loi forestière, loi n° 16 - 2000 du 20 novembre 2000 portant code forestier qui consacre la gestion durable des forêts garantissant une exploitation soutenue des bois et une conservation des écosystèmes ; et jusqu’à la promulgation de la nouvelle loi forestière n°33 – 2020 du 8 juillet 2020 portant code forestier qui aborde de nouvelles questions climatiques et environnementales ; le développement et la diversification de la transformation constitue l’une des principales stratégies pour la mise en œuvre de cette politique, avec une utilisation rationnelle des bois, avec une valeur ajoutée plus importante du secteur forêt – bois et la création de plus d’emplois.

The present business environment offers a wide scale of production and it is increasingly difficult to find a product standard which can distinguish the producer from competitors. The pressure of lobby groups and legislation arrangements force the society to reflect a need for ecologic and sustainable thinking. The current trend and requirements of EU are the implementation of certified systems and production of wooden products from certified wood. This paper focused on the present situation in the supply of products from certified wood and analyses an exercitation of eco-philosophy in the business of wood processors, the rate of manufacturing of certified wooden products, as well as reasons and benefits of certified production. This paper presents selected results of primary research carried out in Czechia which was focused on the investigation of economic impacts of wood products manufacturing from certified raw wood. All presented results emphasise the need for voluntary market tools with ecologic character. Keywords: Certification system, certified wood, wood processing, eco philosophy.

In a competitive business environment at the Bottom of the Pyramid smallholders supplying global value chains may be thought to be at the whims of downstream large-scale players and local market forces, leaving no room for strategic entrepreneurial behavior. In such a context we test the relationship between the use of strategic resources and firm performance. We adopt the Resource Based Theory and show that seemingly homogenous smallholders deploy resources differently and, consequently, some do outperform others. We argue that the ‘resource-based theory’ results in a more fine-grained understanding of smallholder performance than approaches generally applied in agricultural economics. We develop a mixed-method approach that allows one to pinpoint relevant, industry-specific resources, and allows for empirical identification of the relative contribution of each resource to competitive advantage. The results show that proper use of quality labor, storage facilities, time of selling, and availability of animals are key capabilities.

This work is devoted to the study of the effect of ultraviolet rays for the surface activation of pine wood thermally modified at temperatures of 180−240 °C in order to increase the surface roughness, enhance the wettability of thermal wood and the adhesive strength of the glue in the production of wood block furniture panels. Studies were carried out to measure the contact angle of wettability of thermally modified wood samples of pine, as a result of which it was determined that the ultraviolet treatment process contributes to an increase in the adhesion properties of the surface layer of thermally modified wood by more than 13% due to the reactivity of ultraviolet rays to oxidize and degrade ligno-containing wood products. At the same time, the most active process of surface activation takes place during 60 min of ultraviolet irradiation of wood with a total irradiation of at least 125 W/cm2. It was revealed that the combined effect of two-stage wood processing, including preliminary volumetric thermal modification followed by surface ultraviolet treatment, causes an increase in the moisture resistance of glued wood products by 24%. So, if the strength of the glue seam when gluing natural wood samples after boiling decreased by 46%, then the samples that underwent two-stage processing showed a decrease only by 22%. In connection with the results obtained, an improved technology for the production of furniture boards for the manufacture of moisture-resistant wood products is proposed.

Forest natural resources in Indonesia are one of the contributors to the fulfilment of human life and development capital. However, the use of forest resources without regard to aspects of sustainability will cause damage and even extinction of the forest. Therefore, green products today have become stronger demands from various groups. The procurement of goods/services within the government has been implementing a Sustainable Public Procurement that fulfils 3 (three) aspects, namely, economic, social and environmental interests. This paper observes Timber Legality Verification System policies in supporting the provision of green products for the forestry sector and Sustainable Public Procurement that will support the achievement of sustainable development. Timber Legality Verification System policy guarantees the provision of wood products by wood processing industry that contributes to realizing good forest governance to combat illegal logging and illegal trade, as well as support improvement in environmental quality. One strategy in fulfilling green products and implementing a Sustainable Public Procurement is to use timber products that have been certified with timber legality. The policy for the use of certified wood products needs to be supported by the implementation rules and information on the list of green products and technical guidelines for the procurement.

Wood processing plants in Poland are recipients of more than 50% of round wood, which is delivered by the State Forests National Forest Holding. Thus playing a crucial role in the technological processing of raw material for all other wood industry branches. Each group of recipients has individual needs and expectations concerning the quality of the raw material such as, its type and the size of the cross-sections of the assortment used for further production. Therefore, it is economically justified for small production plants to abandon the production of narrow groups of assortments, which usually meets the standards of timber for general purposes. The aim is to make wood processing more flexible and lower the quality of raw material to produce assortments for a specific branches of the wood industry. Wood processing experiments were conducted to produce laths for construction purposes. These materials are one of the most important elements of roof constructions. The research proved empirically that it was possible to produce quality class 1 laths (88% of all laths produced) from WC0 class pinewood used as the input raw material and that the quantitative efficiency exceeded 55%.

Eucalyptus wood products contribute significantly to the income of smallholder growers in many parts of Ethiopia. This has incentivized smallholders to convert arable lands to Eucalyptus plantation. Given the limited attention and availability of empirical evidence, this study examined the Eucalyptus wood products value chain in terms of the actors engaged, the type and importance of channels, margins analysis and the overall value chain governance in the main Eucalyptus growing areas of the Blue Nile highlands of Northwestern Ethiopia in 2019/2020. Sources of data were randomly selected 388 Eucalyptus grower households and 166 Eucalyptus wood traders, complemented by an interview with key informants, group discussions and direct observations. The results reveal that a total of 2,051,114.75 m3 of Eucalyptus wood was produced in the study area and Eucalyptus plantations are expanding over crop lands at a rate of 102.35 ha a year on average. Many actors involved handle a large volume of wood in eight main channels with a high disparity in the shares of the margins. We found that Eucalyptus is the main source of cash earning, contributing about 45.76% to the total annual income of smallholder growers. Little policy attention, a lack of sectoral integration, missing infrastructure and an absence of modern wood processing factories are among the key challenges impeding the performance of the wood sector value chain. There are however existing opportunities for the development of the wood sector value chain such as favorable growing conditions and the spectacular growing demand for wood products. The study provides valuable insights about the wood sector value chain and actions towards ensuring sustainable value chains and the commercialization of the sector.

In current business environment we need to search new tools of state industrial policy. World and domestic experience, as well as theoretical studies confirm that the use of cluster approach to promoting the development of integrated economic systems contributes to improving the competitiveness of industries, regions and country as a whole. The aim of this study is to analyze the conceptual foundations of cluster creation in the forest sector of economy of Sverdlovsk region taking into account of the essential features of economic and technological reality, and the current state of the state of cluster policy. The analysis of the legal framework helped to identify the forms of state support for cluster formations and their requirements and their specialized institutions to obtain official status. The study identified six currently existing regional forestry clusters. Formed clusters will contribute to the development of the industry, but their number is insufficient to improve the competitiveness and innovative development of forest sector economy as a whole. Timber industry complex of Sverdlovsk region has significant potential to increase its contribution to economic development of the region. Development opportunities of the forestry sector are explained by the presence of established infrastructure, logging and timber processing, and significant resource base of the industry. There are enterprises of forestry, pulp and paper, wood processing, wood chemical industry in the region. Sverdlovsk region has a number of problems that would be mitigated and partially solved through the establishment of timber industry cluster. In this work, the structure of the regional wood industry cluster is suggested, the assumptions and risks of its creation are analyzed, the composition of the participants of the "core" of the cluster is substantiated. The most appropriate mechanisms of state support and quantitative performance indicators of the cluster are offered to ensure the efficient operation and further development of the cluster.
