“…Studies on wood chip storage in Europe [12,15,25] corroborate the findings of this study in regards to pile protection. Krzyżaniak [25] found that moisture content decreased from 52.5% to 20.0% over one year when biomass materials were protected with covers made of gas-permeable materials, while observing increases in moisture content for unprotected piles.…”

“…Several research studies have examined the effect of various factors such as the particle size, composition of the material, geometries of storage piles, geographic location, covering system, microbial communities, initial moisture, and length of storage on the fuel quality of stored wood chips [9][10][11][12][13][14]. High moisture content is an important driver for the development of fungal and bacterial communities that play a key role in reducing fuel quality and catalyzing the process of self-ignition [9].…”

Short-rotation woody crops (SRWC) have the potential to make substantial contributions to the supply of biomass feedstock for the production of biofuels and bioproducts. This study evaluated changes in the fuel quality (moisture, ash, and heating value) of stored spring harvested shrub willow (Salix spp.) and hybrid poplar (Populus spp.) chips with respect to pile protection treatments, location within the storage piles, and length of storage. Leaf-on willow and poplar were harvested in the spring, and wood chips and foliage with moisture content in the range of 42.1% to 49.9% (w.b.) were stored in piles for five months, from May to October 2016. Three protection treatments were randomly assigned to the piles. The control treatment had no cover (NC), so piles were exposed to direct solar radiation and rainfall. The second treatment had a canopy (C) installed above the piles to limit direct rainfall. The final treatment had a canopy plus a dome aeration system (CD) installed over the piles. Covering piles reduced and maintained the low moisture content in wood chip piles. Within 30 days of establishment, the moisture content in the core of the C pile decreased to less than 30%, and was maintained between 24%–26% until the end of the storage period. Conversely, the moisture content in the NC piles decreased in the first two months, but then increased to the original moisture content in the core (>45 cm deep) and up to 70% of the original moisture content in the shell (<45 cm deep). For all the treatments in the tested conditions, the core material dried faster than the shell material. The higher heating value (HHV) across all the treatments increased slightly from 18.31 ± 0.06 MJ/kg at harvest to 18.76 ± 0.21 MJ/kg at the end of the storage period. The lower heating value (LHV) increased by about 50% in the C and CD piles by the end of the storage period. However, in the NC piles, the LHV decreased by 3% in the core and 52% in the shell. Leaf-on SRWC biomass stored in piles created in late spring under climatic conditions in central and northern New York showed differing moisture contents when stored for over 60–90 days. Overhead protection could be used to preserve or improve the fuel quality in terms of the moisture content and heating value if more than two months of storage are required. However, the implementation of such management practice will depend on whether the end users are willing to pay a higher price for dryer biomass and biomass with a higher LHV.

“…In relation to harvest technologies apart from moisture content, the particle size distribution of chips is the other important characteristic for biomass quality. Pari et al (2013) have evaluated the effects of the harvesting method on the quality of wood chips in poplar short-rotation plantations in Italy. Single-pass and double-pass harvesting were compared.…”

International audienceThe global energy consumption was 540 EJ in 2010, representing an increase of about 80 % from 1980. Energy demand is predicted to grow more than 50 % by 2025. Fossil fuels will supply about 75 % of the future energy demand in 2030–2050 if there are no significant technological innovations or carbon emission constraints. This will induce in a substantial increase of CO2 atmospheric concentration and, in turn, adverse climatic impacts. A solution to this issue is to replace fossil fuels by renewable fuels such as biomass. For instance cultivated woody biomass shows many advantages such as allowing multiple harvests without having to re-plant. Poplar, eucalyptus, salix, paulownia and black locust are common examples of woody biomass. Here we review the current situation and future tendency of renewable energy focusing on solid biomass in Europe and Spain. We also discuss the potential production for short-rotation plantations in the bioenergy sector and existing constraints for the implantation in Spain in a sustainable context. Countries with low biomass resources and high targets for renewable electricity may have to depend on imported solid biomass, whereas countries with wide solid biomass resources benefit from international markets. The expansion of short-rotation plantations is much lower than expected in some countries such as Spain

“…The chipping operation can be done during the biomass harvest [7] or some months after tree cutting [8]. This operation can be performed by two different groups of machines: chippers -machines using sharp tools (knives) to cut or slice wood; and grindersmachines using blunt tools (hammers) to smash or crush wood [9].…”
