The main aim is to test the influence of anatomical structure (grain direction and elements size), wood hardness machining conditions on surface roughness.180 samples defect-free were obtained from beech, oak pine processed with different methods (planning, sanding 60 grit or 180 grit).Roughness, hardness, analysed using international methodologies.An analysis variance data all four factors in experimental design performed.Results showed that processes species are significantly affect...
European forest stands of small-diameter trees can provide industries with biomass as an alternative to fossil use. Small-tree harvesting is costly using conventional methods but accumulating felling heads (AFH) in combination a novel boom-corridor thinning (BCT) technique increase harvester productivity and supply cost efficiency. This method has great potential reduce costs, its environmental impact compared selective (ST) needs be determined. The objectives this study were therefore...
Post-wildfire regenerated Mediterranean pine stands have a high risk of wildfire recurrence. Preventive clearings are frequently applied in mix systematic and selective ways, being potential biomass source using technologies such as the collector-bundler BioBaler WB55. Our research aimed to compare with chain mulcher performing mulching 50% vs. 67% stand surface over 11.4 ha dominated by Pinus pinaster Ait. after severe wildfire. Time studies included machinery GPS follow-up weighing each...
Aim of study: To determine the effect on wood from Pinus sylvestris treatment with preservatives mechanical properties and to establish relation between penetration compression strength.Area SpainMaterial Methods: 40 samples defect-free L. were treated Light Organic Solvent Preservative (Vacsol Azure WR 2601) 50 waterborne Copper Azole (Tanalith E 3492). control not (water or preservative). Mechanical resistance static bending, modulus elasticity strength parallel grain compared untreated...
Aim of study: To analyze the environmental and economic performance a multifunctional poplar plantation (MPP), which was managed to produce timber for sawn wood chips bioenergy. Area The located in Southern Spain producing roundwood woodchips (from tops branches). Material methods: life cycle assessment (LCA) methodology chosen perform impact from cradle-to-gate perspective. Capital goods, including machinery-manufacturing processes, were included. One oven dry tonne (odt) forest biomass as...
Forests are a source of renewable biomass, and their utilisation will play vital role in the transition towards climate-neutral economy. Small-diameter tree management could contribute to this via providing biomass for sustainable uses fostering growth long-lifecycle bioproducts. The small-diameter trees EU is still low since new technologies work models required make operations economically profitable, environmentally sound, socially attractive. supply from stands dependent on forest owners...
Due to socioeconomic transformations in the 20th century, Quercus pyrenaica Willd. coppices Spain, as well other European coppices, have experimented an abandonment and lack of intervention leading stagnant high density stands with fragile health due competition. Thinnings are often required ensure their stability health, producing forest products such firewood or biomass, which key energy sources a carbon-neutral economy. However, thinnings seldom performed because they economic...
Samples of wood from Populus à canadensis (9,5 % moisture) were treated with olive oil at 195 °C simultaneously 15 or 30 compression densification, and the results compared samples subjected to heat treatment without control samples. The density increased by 18 %, 43 1,5 respectively, barely changed over six subsequent months stored inside laboratory room (at approximately 65 RH, 20 °C). This was due fact that slight weight increment caused additional moisture content offset increase in...

Coppices are a major potential source of forest biomass in Spain, where they occupy around 4M ha. Quercus coppices mostly neglected because their high harvesting costs and the small size products. This makes them very interesting to test compare alternative means for utilizing resources an optimized way. Hence, comparative study motor-manual mechanized felling bunching was conducted when thinning dense coppice stands two most important oak species Spain obtain bioenergy use. In particular,...
Several works have analyzed the alteration in mechanical strength of wood after application protective substances. However, it remains unclear whether significant differences obtained are caused by substances, pressure and vacuum conditions used treatment, or simultaneous effect both. In this study, 123 samples from Pinus sylvestris were tested for bending, 85 compression parallel to grain. These randomly distributed three groups (treated with water pressure, vacuum, control simply submerged...
