The present paper analyzed the environmental assessment of short rotation willow plantations in Sweden based on the standard framework of Life Cycle Assessment (LCA) from the International Standards Organisation. The analysis is focused on two alternative management regimes for willow plantations dedicated to biomass production for energy purposes. The data used included the averages of a large sample of commercial plantations. One of the scenarios is carried out under nitrogen based fertilized conditions and the other under non-fertilized management with total biomass yields (dry weight) of 140t/ha and 86t/ha over a 21 and 22-year life time respectively. The environmental profile was analyzed in terms of the potentials for abiotic depletion, acidification, eutrophication, global warming, ozone layer depletion, photochemical oxidant formation, human toxicity, fresh water aquatic ecotoxicity, marine aquatic ecotoxicity and terrestrial ecotoxicity. In addition, an energy analysis was performed using the cumulative energy demand method (CED). The application of nitrogen based fertilizers allows an increase in the biomass yield per ha of up to 40% although the contributions to almost all impact categories, particularly the eutrophication potential and toxicity potential impact categories are also considerably higher. Conversely, due to the higher biomass yields achieved with fertilization of these willow plantations, that regime presents a better overall environmental profile in terms of energy yield and global warming potential.
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 January 2014.
All research outputs
#12,357,273
of 34,404,538 outputs
Outputs from Science of the Total Environment
#15,557
of 36,893 outputs
Outputs of similar age
#78,924
of 202,928 outputs
Outputs of similar age from Science of the Total Environment
#46
of 97 outputs
Altmetric has tracked 34,404,538 research outputs across all sources so far. This one is in the 38th percentile – i.e., 38% of other outputs scored the same or lower than it.
So far Altmetric has tracked 36,893 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 12.1. This one is in the 41st percentile – i.e., 41% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 202,928 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 33rd percentile – i.e., 33% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 97 others from the same source and published within six weeks on either side of this one. This one is in the 19th percentile – i.e., 19% of its contemporaries scored the same or lower than it.
