The study focused on the maximum gross vehicle weight (GVW) limits allowed with different timber truck configurations, typical payloads in timber trucking, the road transportation share of the total industrial roundwood longdistance transportation volume, and the average long-distance transportation distances and costs of industrial roundwood. The study was carried out as a questionnaire survey. The questionnaire was sent to timber transportation logistics experts and research scientists in the 30 countries with the largest industrial roundwood removals in Europe, as well as selected major forestry countries in the world (Argentina, Australia, Brazil, Canada, Chile, China, Japan, New Zealand, South Africa, Türkiye, the United States of America and Uruguay) in February 2022, and closed in May 2022. A total of 31 countries took part in the survey. The survey illustrated that timber trucking was the main long-distance transportation method of industrial roundwood in almost every country surveyed. Road transportation averaged 89% of the total industrial roundwood long-distance transportation volume. Timber truck configurations of 4 to 9 axles with GVW limits of around 30 tonnes to over 70 tonnes were most commonly used. The results indicated that higher GVW limits allowed significantly higher payloads in timber trucking, with the lowest payloads at less than 25 tonnes, and the highest payloads more than 45 tonnes. The average road transportation distance with industrial roundwood was 128 km, and the average long-distance transportation cost in timber trucking was €11.1 per tonne of timber transported. In the entire survey material, there was a direct relationship between transportation distance and transportation costs and an inverse relationship between maximum GVW limits and transportation costs. Consequently, in order to reduce transportation costs, it is essential to maximise payloads (within legal limits) and minimise haul distances. Several measures to increase cost- and energy-efficiency, and to reduce greenhouse gas emissions in road transportation logistics, are discussed in the paper. On the basis of the survey, it is recommended that upto-date statistical data and novel research studies on the long-distance transportation of industrial roundwood be conducted in some countries in the future.

10. Raba lesa, tržne količine in projekcije potencialov okroglega lesa listavcev v SlovenijiŠpela Ščap, Matevž Triplat, 2023, izvirni znanstveni članek Povzetek: Gozdarstvo in lesnopredelovalna industrija sta za Slovenijo strateško pomembni gospodarski panogi, ki v zadnjih letih krepita svojo vlogo v biogospodarstvu. Raziskava se osredotoča na problematiko rabe lesa listavcev v Sloveniji. Za akterje, ki se ukvarjajo z rabo lesa listavcev, je pomembno vedenje o razpoložljivi količini domačega lesa, ki se lahko ponudi na trgu. V raziskavi je bila nadgrajena leta 2014 razvita metodologija za oceno količin in potencialov lesa listavcev. Za prihodnje odločanje o razvoju gozdarskega in lesnopredelovalnega sektorja je potrebno tudi raziskovanje tokov lesa, zato je bila v raziskavi opravljena anketa med večjimi predelovalci okroglega lesa listavcev. Ocenjeni teoretični tržni potencial hlodovine listavcev v slovenskih gozdovih je v letu 2021 znašal 0,777 mio m³ in 2,372 mio m³ ocenjeni teoretični tržni potencial lesa slabše kakovosti. Ocenjeni dejanski tržni potencial hlodovine listavcev je v letu 2022 znašal 0,528 mio m³, lesa slabše kakovosti pa 0,741 mio m³. Projekcije potencialov hlodovine listavcev kažejo, da bodo v letu 2025 na trgu podobne količine lesa kot leta 2022. Poraba okroglega lesa listavcev je v letu 2021 znašala 1,433 mio m³, od tega je bilo 0,906 mio m³ lesa predelanega za energetske namene, ostalih 0,527 mio m³ pa v industriji. Rezultati raziskave potrjujejo problematiko rabe lesa listavcev v Sloveniji in nakazujejo priložnosti slovenskega gozdno-lesnega sektorja za prihodnji razvoj.Forestry and wood processing are strategically important industries for Slovenia and have been strengthening their role in the bioeconomy. The study addresses the use of hardwood timber in Slovenia. For actors involved in the use of hardwood timber, it is important to know the available volume of domestic timber that affects the market. For this reason, the survey presented in this work builds on the methodology for estimating the volumes and potentials of hardwood timber developed in 2014. For future decision-making on the development of the forestry and wood-processing sector, it is also essential to analyse wood flows carried out among the major wood processors of round hardwood timber. The estimated theoretical market potential for lower-quality hardwood in Slovenian forests in 2021 was 2.372 million m³, and the estimated theoretical market potential for logs was 0.777 million m³. The estimated real market potential for lower-quality hardwood in 2022 was 0.741 million m³, and for hardwood logs 0.528 million m³. Projections of hardwood potential show that similar volumes of wood will be on the market in 2025 as in 2022. The consumption of round hardwood in 2021 was 1.433 million m³, of which 0.906 million m³ was processed for energy purposes, and the remaining 0.527 million m³ was used in industry. The survey results confirm the concerns about hardwood wood use in Slovenia and indicate opportunities for the future development of the Slovenian forest and wood sector.
