A life-cycle-assessment for timber supply from the forest to the plant is the goal of the project. A special focus is on the evaluation of new technologies. The most important environmental impacts (e.g. climate change, acidification, eutrophication) should be analysed for the supply of 1 m³ timber (saw logs, industrial wood, energy wood) for selected case study regions. The performance of existing and new technologies (hybrid propulsion, electric vehicles, rechargeable batteries, transport optimization etc.) will be compared. The environmental impacts will be analysed for different harvesting systems (from motor-manual to fully mechanized) and regions (coniferous and deciduous forest, flat and steep terrain). Processes with a high environmental impact and therefore a lot of room for improvement will be identified. Based on this, individual solutions can be derived for every model forest enterprise. The results of the study should be used by the forest lobby (e.g. chamber of agriculture) to inform the public about environmentally friendly supply of wood products. The transfer of knowledge should also be executed by BOKU and by forest training centers.

According to the EU Directive 2015/719 which is laying down maximum authorised dimension and weights subsection 13 is pointing out to take measures for the detection of infringements of vehicles regarding weight limits until May, 27 2021 to ensure undistorted competition between operators. This is directly affecting the round wood transport in Austria. For weighing respectively estimating the transported load of round wood with truck and trailer from forest to customer different technical solutions are available but not common. Additionally detailed information regarding the performance of crane scales in round wood transport is not available. Using crane scales in round wood transport only an accurate estimation of the load is interesting not an exact weight for sale and contracting. But this can ensure that weight limits are not exceeded and load capacities will be utilized. At the moment there are different technical solutions available on the market. A current product for estimation the load in round wood transport combines the information of hydraulic pressure and acceleration whereby a classical weighing link can be omitted. Both, the latest invention and a classic weighing link with integrated acceleration sensors should be analyzed and tested regarding the following aims: • Carrying out a market overview for current solutions regarding crane scales for round wood transport • Detailed process- and performance analysis of transport activities, accuracy and potential support for drivers and entrepreneurs during their daily business • Economic assessment of acquiring and using crane scales in round wood transport based on detailed process- and performance analysis

Steep country harvesting has been identified as the main bottleneck to achieve greater profitability in the forestry sector of New Zealand and Australia. The forest industry has had serious problems in efficiency, work safety and environmental impacts. The vision of the forestry sector is to develop innovative harvesting technologies to realise substantial productivity gains, improve work safety in steep terrain harvesting and to minimize environmental impacts. An improvement should be realized by developing an advanced steep terrain timber harvesting system based on innovative Austrian technology. The company Koller has the experience and knowledge to produce and to assemble a system which fits perfectly to the requirements of the target countries. The focus will be on capacity improvements, automation and the implementation of on-board monitoring systems. By implementing the new system, the efficiency of harvesting operations should increase at least by 30%, achieved through product innovations and better organisation of work. Furthermore, working safety should be increased by reducing the number of accidents by 20%. Fuel consumption should be decreased by 20%, amongst others by use of hybrid technology. The developed system will be applied, tested and validated in the target countries in order to demonstrate the system to relevant stakeholders, to train operators and to quantify the improvements of the new technology in terms of productivity, costs, fuel consumption, ergonomics, work safety etc. On-the-job training is a key element in order to improve one's acceptance, capability, capacity, and performance in using novel technologies. This should also help to establish the new technology on a long term perspective. The results of the project will be disseminated in various channels. An exploitation strategy promotes the advanced harvesting system in the forestry market sector
