“…Residual biomass of forest origin is collected in the forest using a tractor and a winch (a machine used in forestry sites to move plant masses placed in positions that cannot be reached by self-propelled vehicles) (Figure 3). With reference to the indirect drag of the residual biomass (use of the tractor equipped with a winch), a productivity of 1.35 t/h was calculated for the tractor equipped with a forestry winch [13], while and an average consumption of 4.6 l/h of diesel as fuel was estimated [14] (Table 3).…”

“…Figure 3. Forestry tractor with a winch The methods of collection and drag are: -Indirect drag: the tractor remains stationary and the wood collection is carried out by means of the winch; -Direct drag: an activity in which the load (biomass) moves together with the towing vehicle (tractor and winch).With reference to the indirect drag of the residual biomass (use of the tractor equipped with a winch), a productivity of 1.35 t/h was calculated for the tractor equipped with a forestry winch[13], while and an average consumption of 4.6 l/h of diesel as fuel was estimated[14] (Table3).In order to examine the movement of the biomass to the storage site (direct drag), an average drag distance of 1 km was assumed[15].…”

The paper describes the results of a Life Cycle Assessment study of wood chips obtained from a residual forest biomass, to be used for energy purpose. The analysis is referred to 1 kg of wood chips as functional unit. The system boundaries include the collection of the residual biomass, the chipping process of biomass, the collection and transport of wood chips to the energy plant. The results show that the supply chain examined, with reference to the functional unit, causes an impact of 0.027 kg CO2eq and a consumption of 0.406 MJ of primary energy. A dominance analysis was developed to identify the most impactful stages of the production chain: the steps that contribute most to the impacts within the supply chain are the indirect drag and the chipping process, responsible for the 42% of the overall greenhouse gas emissions and primary energy consumption. Lastly, a sensitivity analysis was carried out, to assess the variation of the impacts related to the distance between the wood chips production site and the place of use. The sensitivity analysis shows that is important to have short supply chains within the proposed domain in order to lower the energy and environmental impacts.

“…The data on the productivity and fuel consumption of the chainsaws, forest tractors with winch and chipper have been taken from Paletto et al. (2018) [49]. For tree felling and harvesting, the average fuel consumptions is 0.6 l h −1 of gasoline for the medium chainsaws (productivity of 5.81 m 3 h −1 ) and 4 l h −1 for the forest tractor with winch (productivity of 7.55 m 3 h −1 ) respectively.…”

Objective The objectives of the European Union (EU) policy agenda are to reduce the greenhouse gas emissions and to decrease the dependence of EU member countries from fossil fuel sources. In order to achieve these policy objectives, in the last decades the number of biomass power plants has increased throughout the EU. This study analyzed the environmental impacts of the bioenergy systems at global and local level to support communication and information strategies to increase social acceptance and to reduce conflicts between stakeholders. The environmental impacts were estimated to a sample of biomass power plants in North Italy selected based on the size, feedstock and type (cogeneration or heating). The study aims to identify and evaluate the environmental impacts associated with the thermal energy production in biomass power plants using a Life Cycle Assessment (LCA) approach. Materials and methods For each biomass district plant an LCA analysis was performed to: compare the environmental impacts associated with the production of the same functional unit, quantifying and valuating the environmental performance deriving from the production process life cycle, and highlighting the production phases with greater impact. Results The results show an average climate change impact by biomass energy plant of 45.84 gCO 2eq MJ −1 and a range between 14.93 gCO 2eq MJ −1 and 90.70 gCO 2eq MJ −1 . The results show that the size of the biomass energy plant (less than 1 MW or more than 1 MW) and the feedstock used (forest or sawmill woodchip) are two main variables that influence many categories of environmental impact.

In the last decades, the energy policy of European Union (EU) has fostered the use of biomass from forests and outside forests for energy purposes. Firstly, the Green Paper on renewable energies of the European Commission, then, the Directive 2009/28/EC on the promotion of the use of energy from renewable sources, the objectives of reducing the greenhouses gases (GHG) emissions and increasing the share of final consumption covered by renewable sources have been established. In this context, the present study investigated the flow of wood residues for energy use in the Trentino provinceinvolving 82 wood processing enterprises (74% of total enterprises) and 22 biomass energy plants (85% of total biomass energy plants)and quality of raw material used. The results show that in the Trentino province 100% of wood residues produced by wood processing enterprises are sold in the market (90.6%) or re-used within the enterprise (9.4%). Concerning the biomass sold on the market, 46% of wood biomass is marketed within the Trentino province, while 54% is marketed outside the province (Bolzano province, Veneto and Lombardy region). The biomass energy plants mainly use woodchips from forest and sawmills (86%), while sawdust and bark cover the remaining 10% and 4%, respectively. The biomass energy plants sample involved in the survey buys mainly raw material from traders (42.5%) followed by wood processing enterprises (34.3%) and forest enterprises (23.2%). Regarding the quality of wood biomass, only 54.5% of biomass energy plants sample checks the water content, while 41% buy certified woodchips. The results of this study highlight that forest-wood chain in the Trentino province is efficient in re-using wood residues produced in accordance with the principles of the circular bioeconomy, while there are still margins for improvement about the controls of the quality of raw materials used and to enhance of wood products of high added value (bio-textiles, bio-plastics).
