Abstract:
The recent growth in global pellet demand has been driven largely by EU renewable energy targets to cut GHG emissions by 20% compared to 1990 levels by 2020. European policies promoting bioenergy are partly based on analyses showing that increased use of bioenergy can contribute to both energy and climate objectives. The rapid growth of the pellet market has been so remarkable that wood pellets represent one of the largest internationally traded solid biomass commodities. In large-scale biomass supply chains, the increased energy density of pellets reduces costs throughout the supply chain for handling, storage and transport. The present study examined the wood pelletizing process carried out using woody biomass derived from trees cultivated as SRF poplar plantations. In the production process, both whole plants and stems at the third and sixth year of vegetation were utilized as raw material. The quality of the pellets made with the 6-year-old poplar trees is better than those made with the 3-year-old trees, in terms of bulk density, length and ash content. Furthermore, the use of the wood fractions, namely branches, in the production process would seem to influence the physical parameters more than the energetic ones.
