Publication: Sustainability impacts of increased forest biomass feedstock supply

Sustainably managed forests provide renewable raw material that can be used for primary/secondary conversion products and as biomass for energy generation. This paper

Tuomasjukka et al from EFI evaluated the economic, environmental and social sustainability impacts of making the potentially available timber available with current and technologically improved value chains.

Their publication ‘Sustainability impacts of increased forest biomass feedstock supply – a comparative assessment of technological solutions’ in the International Journal of Forest Engineering is now available open access:

Publication: Spatial distribution of the potential forest biomass availability in Europe

European forests are considered a crucial resource for supplying biomass to a growing bio-economy in Europe. This study aimed to assess the potential availability of forest biomass from European forests and its spatial distribution. We tried to answer the questions (i) how is the potential forest biomass availability spatially distributed across Europe and (ii) where are hotspots of potential forest biomass availability located?

Verkerk from EFI et. al analysed the total availability of forest biomass and spatial distribution of woody biomass potential for 39 European countries. They found out that the distribution of biomass potentials that are currently unused only partially coincides with regions that currently have high levels of wood production.

Publication: Decreasing Fuel Consumption of Excavator-Based Harvesters with Machine Control System

Compared with purpose-built units, excavator-based harvesters offer many advantages, but they consume more fuel. Fuel efficiency can be increased by a better interface between the excavator and the harvester head.

Spinelli et al from CNR just published testing results of a new adaptation kit in Forests 2019 (10(1), 43; https://doi.org/10.3390/f10010043). The kit is specifically designed to improve the communication between these two components. After installing the adaptation kit, productivity increased 6%, while fuel consumption per hour decreased 3.5%. Fuel consumption and CO2 emissions per product unit decreased 10%, as an average.

Publication: Modifying the settings of CTL timber harvesting machines to reduce fuel consumption and CO2 emissions

Following extensive field trials, LUKE just published results on experiments with Ponsse harvesters:

  • Adjustment of machine settings had an effect on fuel consumption and CO2 emissions.
  • Large energy saving potential in the Nordic and Baltic regions alone:
  • Potential savings may amount to almost 50 million litres of diesel per year.
  • Stem size also had a strong effect on fuel consumption and productivity.
