“…A high trace element concentration in the soil does not seem to impair biomass production in this species, at least at the levels tested in this work. The improvement in the nutritional status of the plants after adding organic amendments to the most degraded soil and the observed increase in biomass yield in both types of contaminated soil after compost addition suggest that the application of certain organic waste could be used to increase P. fortunei biomass even in highly degraded soils, in agreement with previous studies describing Paulownia species as being highly responsive to fertilization (Joshee, 2012). By planting P. fortunei for energy production, the afforestation of contaminated soils could have added economic value, in addition to the environmental benefits derived from the revegetation of contaminated soils.…”

The plantation of fast growing trees in contaminated sites, in combination with the use of organic wastes, could partially solve a dual environmental problem: the disposal of these wastes and the improvement of soil quality in these degraded soils. This study evaluated the effects of two composts amendments on the quantity and quality of Paulownia fortunei biomass and on syngas production by biomass gasification, produced by plants growing on trace elements contaminated soils. Compost increased biomass production to values similar to those produced in non-contaminated soils, due to the improvement in plant nutritional status. Moreover, biomass quality for gasification was increased by compost addition. Trace element accumulation in the biomass was relatively low and not related to biomass production or the gas quality obtained through gasification. Thus, P. fortunei plantations could pose an opportunity to Preprint submitted to Elsevier 2 improve the economic balance of the revegetation of contaminated soils, given that other commercial uses such as food or fodder crop production is not recommended in these soils.

“…Referring to yield production, the stem biomass obtained in the first resprouts was lower than that offered by other trials in Paulownia which applied a higher irrigation dose and in wetter areas (for example [10,16,17], with yields of up to 40 t⋅ha −1 ). However yield production was relatively high if compared with other experimental Paulownia plantings in semi-arid areas.…”

“…Actually, this genus is suitable to reclaim abandoned farmlands or to restore soils, where special emphasis is focused on biomass production [10]. For this reason, the genus Paulownia has been used in several recent studies which have been focused on its potential for timber production [10], its use in agroforestry practices and intercrops [11], biotechnology and in vitro cultivation [12], soil activity in Paulownia plantations [13], and the chemical composition of its wood [14]. Regarding biomass production, a recent research analyzed the woody biomass yield for clones monitored at different locations in south Spain.…”

Abstract:In semi-arid regions, afforestation with fast-growing species cultured with low irrigation can be an effective approach for environmental protection. An experiment was conducted to evaluate the stem biomass production of Paulownia in a semi-arid climate and clay soils under contrasting low-irrigation and fertilization treatments. The stem biomass at the stand level was estimated by applying allometric equations fitted in sample resprouts and inventory data. The results show that biomass production improved when either irrigation or fertilizer was added, but the combination of a higher dose of irrigation and fertilization did not lead to the highest biomass production; thus water availability was the main factor controlling biomass production. Under the higher dose of irrigation, the absence of a fertilizer effect would be due in part to the fertile soil, which could supply sufficient nutrients for Paulownia growth at the higher level of soil moisture. The stem OPEN ACCESSForests 2014, 5 2506 biomass estimated ranged from 2.14 to 4.50 t⋅ha −1 (lower irrigation dose without fertilization, and higher irrigation with fertilization). The greater production was similar to other studies in the Mediterranean area receiving more irrigation. Thus, this study permitted us to understand the potential of Paulownia to provide biomass in semi-arid environments with low irrigation due to water use restrictions.

“…The composition of biomass varies among species. In general, lignin (~25%) and carbohydrates or sugars (~75%) are identified to be the dominant components [2][3][4][5]. The carbohydrate fraction contains many sugar molecules linked together in long chains or polymers.…”

Evaluation of the Life Cycle Greenhouse Gas Emissions from Different Biomass Feedstock Electricity Generation Systems

This paper evaluates life cycle greenhouse gas (GHG) emissions from the use of different biomass feedstock categories (agriculture residues, dedicated energy crops, forestry, industry, parks and gardens, wastes) independently on biomass-only (biomass as a standalone fuel) and cofiring (biomass used in combination with coal) electricity generation systems. The statistical evaluation of the life cycle GHG emissions (expressed in grams of carbon dioxide equivalent per kilowatt hour, gCO 2 e/kWh) for biomass electricity generation systems was based on the review of 19 life cycle assessment studies (representing 66 biomass cases). The mean life cycle GHG emissions resulting from the use of agriculture residues (N = 4), dedicated energy crops (N = 19), forestry (N = 6), industry (N = 4), and wastes (N = 2) in biomass-only electricity generation systems are 291.25 gCO 2 e/kWh, 208.41 gCO 2 e/kWh, 43 gCO 2 e/kWh, 45.93 gCO 2 e/kWh, and 1731.36 gCO 2 e/kWh, respectively. The mean life cycle GHG emissions for cofiring electricity generation systems using agriculture residues (N = 10), dedicated energy crops (N = 9), forestry (N = 9), industry (N = 2), and parks and gardens (N = 1) are 1039.92 gCO 2 e/kWh, 1001.38 gCO 2 e/kWh, 961.45 gCO 2 e/kWh, 926.1 gCO 2 e/kWh, and 1065.92 gCO 2 e/kWh, respectively. Forestry and industry (avoiding the impacts of biomass production and emissions from waste management) contribute the least amount of GHGs, irrespective of the biomass electricity generation system.
