“…For the sampling procedure, following the methodology defined by Fernandez-Puratich et al [9] to fruit trees, 30 plants inside the plots were selected at random per variety. Then, three representative branches of each plant of at least 10 cm in length and 1 cm in diameter at the base of the branch were measured and extracted.…”

a b s t r a c tThe chip pruning of five different vine-producing wines was physically characterized, and its energetic value was analyzed (calorific value and ashes content principally). The material with a better energy performance was established. TCO2 emissions of this wood biomass were compared with the pine pellet, which is the most currently used solid biofuel in this industry. In both cases, the material obtaining process was studied, along with the fuel production and transport required measured in TCO 2 emitted per tons.This process was done in order to replace the pellets used in the boilers of the vineyards for the chip pruning of the studied vines. The use of chips as solid biofuel inside the vineyard produces a lower TCO 2 emissions than the use of pellets (0.01 and 0.484 TCO 2 , respectively) because less energy is needed for its production and transportation. This resulted in a decrease in the carbon footprint of the analyzed vineyard. The cost of using this chip instead of the pellets inside the vineyard was also calculated, with an annual savings in vineyard fuel requirements of US$ 23,142 from not purchasing pellets while the annual savings of using ashes instead of industrial fertilizer (CaO) is US$ 450.

“…Aside from the environmental benefits gained due to better recyclability compared to more rigid fibers, these materials may offer some economic advantages (Lopez et al 2013). Moreover, the comparatively low density of the cellulosic fibers positively affects the specific mechanical properties (Dittenber and GangaRao 2012;López et al 2012b;Reixach et al 2013a).…”

Orange Wood Fiber Reinforced Polypropylene Composites: Thermal Properties

et al. 2015

A major drawback of natural-based composites is the incorporation of reinforcements that are less thermally stable than the matrix; therefore, the thermal properties of the resultant composite material needs to be studied. In this work, orange wood fibers were used to reinforce polypropylene. The effects on the thermal properties of the polymeric matrix were analyzed. To this end, differential scanning calorimetry (DSC), thermogravimetry (TGA), thermomechanical analysis (TMA), and dynamic-mechanical analysis (DMA) were performed. It was found that the degradation of the material took place in two distinct phases: the reinforcement, close to 250 °C, and the matrix, above 340 °C. DSC results showed that fiber reinforcement did not influence the transition temperatures of the materials, although it did affect the polymer crystallinity value, increasing by 7% when the composite is reinforced with 50% of the lignocellulosic reinforcement. The coefficient of expansion obtained by TMA indicated that thermal expansion decreased as the amount of reinforcement increased. DMA assays showed that the reinforcement did not modify the glass transition (20 to 25 °C) temperature and confirmed that the addition of reinforcement increased the crystallinity of the product.

“…They also analysed the influence in the RSR of crop variety, architecture of tree, aim of pruning or pruning intensity (type of pruning work). The second work team (Fernandez-Puratich and co-workers) developed a dendrometric model to estimate volume of wood in fruit trees [28], including a specific model for assessing volume of wood in branches.…”

“…However it is rare to count on with agricultural inventories describing any dendrometric data-differently to forestry inventories, which usually include it-like stem diameter. Even though dendrometric variables showed good ability to predict the pruning yield according to the conclusions of Velázquez-Martí [24][25][26][27] and Fernández-Puratich [28], these variables should not be considered for building regressions in large-scale assessments. A second reason constraining the implementation of some variables is the difficulty to convert them into quantities or dichotomous information.…”

Building Variable Productivity Ratios for Improving Large Scale Spatially Explicit Pruning Biomass Assessments

2019

Biomass assessments of agro–residues performed at large geographical scales generally base calculations on single constant pruning productivity ratios (RSRs). Reliability of biomass assessments shall be improved if RSRs respond to prevailing regional crop growing conditions. The present paper describes the methodology applied to create geographically varying pruning RSR ratios–tons of dry matter per hectare—for five crop groups: vineyard, olive, fruit species, citrus and dry fruits. A newly created database containing 230 records–from seven EU28 countries—is submitted to statistical analysis. Results reveal that agro-climatic conditions are able to explain a not negligible share of the pruning productivity as dependent variable. Subsequent regression analysis provides two equations—for vineyard and citrus—achieving a reasonable good fitting (R2 0.18 and 0.42 respectively) between RSR and the agroclimatic variables. Analysis of olive, fruit species and dry fruits scatter and whisker plots were useful for zoning and inducing ramp functions. A Geographical Information System (GIS) was utilised to apply the functions to the agroclimatic raster coverages in order to obtain RSR raster grids. Zonal statistic procedures applied by European regional units (NUTs0, NUTs2, NUTs3) provide a specific crop RSR ratio per administrative unit as a principal output of the present work.
