“…The lower heating value, which is used to calculated the available energy, is usually around 18-20 MJ kg −1 in poplar wood on a dry basis [300,301]. Values found in Spain are within a range very similar to those obtained for other European countries, although the characteristics vary, depending on the genotype and the age, ranging from 17.61 to 18.74 MJ kg −1 [137,302,303].…”

“…In Spain, rotations from 2 to 9 years have been tested [110,117,128,137], although few studies have compared different rotation lengths. Hernández Garasa et al [138] determined that the maximum volume production occurred between 3 and 4 years, depending on the genotype planted.…”

“…The ash content, which is negatively related to the energy value and associated with the risk of boiler corrosion [308], varies broadly (1-4%), depending on genotype and site conditions [117,137,231,303]. The fouling and slagging risk derived from ash compositions are known to be very low [308][309][310].…”

“…The combination of a high volatile matter content (much higher than 80%, [137,303,314]), softness of the wood (which is easy to grind), and a low lignin content makes poplar from SRC a promissory feedstock for gasifiers. It can also be used for the generation of bioethanol [287,315].…”

Developing a circular bioeconomy based on the sustainable use of biological resources, such as biomass, seems to be the best way of responding to the challenges associated with global change. Among the many sources, short rotation forest crops are an essential instrument for obtaining quality biomass with a predictable periodicity and yield, according to the areas of cultivation. This review aims to provide an overview of available knowledge on short rotation coppice Populus spp. plantations under Mediterranean conditions and specifically in Spain, in order to identify not only the status, but also the future prospects, for this type of biomass production. The analysis of available information was conducted by taking into consideration the following aspects: Genetic plant material; plantation design, including densities, rotation lengths and the number of rotations, and mixtures; management activities, including irrigation, fertilization, and weed control; yield prediction; biomass characterization; and finally, an evaluation of the sustainability of the plantation and ecosystem services provided. Despite advances, there is still much to be done if these plantations are to become a commercial reality in some Mediterranean areas. To achieve this aim, different aspects need to be reconsidered, such as irrigation, bearing in mind that water restrictions represent a real threat; the specific adaptation of genetic material to these conditions, in order to obtain a greater efficiency in resource use, as well as a greater resistance to pests and diseases or tolerance to abiotic stresses such as drought and salinity; rationalizing fertilization; quantifying and valuing the ecosystem services; the advance of more reliable predictive models based on ecophysiology; the specific characterization of biomass for its final use (bioenergy/bioproducts); technological improvements in management and harvesting; and finally, improving the critical aspects detected in environmental, energy, and economic analyses to achieve profitable and sustainable plantations under Mediterranean conditions.

“…Results obtained for the clones selected in this work are quite high (84.5-87%) compared to those commented in literature, which usually vary from 78.4% to 84.8% [35][36][37]. No great differences are observed between varieties or age clones, although is considered that the short rotation coppice (SRC) usually shows high volatile content [38,39]. Volatile fraction of crust samples is lower than that wood samples, which is in concordance with its lower heating values (see Section 3.9).…”

The cultivation of short rotation coppice (SRC) is a sustainable and ecological alternative for the production of energy vectors today. For its use, it is necessary to know the thermochemical properties of the biomass produced, as well as the differences between genotypes and varieties. In this work, the thermochemical properties of five different Populus clones grow up in Mediterranean basin, with two different age categories, are analyzed. The moisture content, wood density, heating value, ash content, energy density, composition and the volatile matter were measured, separating wood and crust fractions. The mean crust content for all clones was near to 10% but it is observed that the youngest clones have higher content of crust and humidity. The 3 year-old clones generally show lower humidity and ash content and higher density of wood and fixed carbon, consequently showing a higher heating value. In addition, 3 year-old clones are encouraged since they have a lower content of majority and minority elements in proportion that can generate less operating and environmental problems.
