“…The mineral composition of biomass determines the ash content. The biomass sample under investigation exhibits an ash content of 5.4%, which falls within the typical range observed for agricultural biomass and indicates a substantial mineral content [48].…”

This study describes an investigation of the pyrolysis and combustion of flax straw as biofuel, focusing on the physicochemical properties and kinetic and thermodynamic parameters, and evaluates the type of degradation products using the thermogravimetry analysis–Fourier transform infrared spectroscopy (TGA-FTIR) technique. Pyrolysis and combustion processes were studied via thermogravimetric analysis at different heating rates of 5-10-15 and 20 °C min, one using three isoconversional methods and one using a model-fitting method. The activation energies, frequency factors, and thermodynamic parameters of flax straw biomass were investigated using different models. The obtained activation energy values for pyrolysis varied between 101.0 and 109.6 kJ mol−1 and for combustion were between 203.3 and 239.2 kJ mol−1. The frequency factors were determined to be 1.7 × 109 for pyrolysis and 1.5 × 1017 s−1 for combustion. The change in Gibbs free energy (ΔG) for the pyrolysis of flax straw was calculated to be 162.6 kJ mol−1, whereas for combustion it increased to 203.9 kJ mol−1. A notable contrast between the volatiles produced by pyrolysis and combustion is evident from the real-time analysis of the degradation products. Specifically, carboxylic acids, aromatics, alkanes, and alcohols are the principal degradation products during pyrolysis, while carbon dioxide is the primary component produced during combustion. These encouraging research outcomes regarding flax straw pyrolysis and combustion can broaden its application in bioenergy and biofuel, thus contributing significantly to it for resource recovery.

“…This paper expands on earlier studies on the seasonal dynamics of nutrient contents in miscanthus (Beale & Long, 1997; Gołąb‐Bogacz et al, 2021; Heaton et al, 2009; Himken et al, 1997; Jensen et al, 2017; Mos et al, 2021; Nassi o Di Nasso et al, 2011; Smith & Slater, 2011) by (1) including very diverse, novel, recently bred miscanthus hybrids; (2) extending the geographical distribution of test locations in Europe; and (3) increasing the temporal resolution of standing crop yield and nutrient contents. Key to this study are the common protocols used throughout growth and ripening to identify G × E factors influencing nutrient relocation to (during growth) and from (during senescence) the shoots and their impacts on yield, quality, and sustainability.…”

Site impacts nutrient translocation efficiency in intraspecies and interspecies miscanthus hybrids on marginal lands

Miscanthus, a C4 perennial rhizomatous grass, is capable of growing in varied climates and soil types in Europe, including on marginal lands. It can produce high yields with low nutrient inputs when harvested after complete senescence. Senescence induction and rate depend on complex genetic, environmental, and management interactions. To explore these interactions, we analysed four miscanthus hybrids (two novel seed‐based hybrids, GRC 3 [Miscanthus sinensis × sinensis] and GRC 14 [M. sacchariflorus × sinensis]; GRC 15, a novel M. sacchariflorus × sinensis clone; and GRC 9, a standard Miscanthus × giganteus clone) in Italy, Croatia, Germany and the UK. Over all trial locations and hybrids, the average aboveground biomass of the 3‐year‐old stands in August 2020 was 15 t DM ha−1 with nutrient contents of 7.6 mg N g−1 and 14.6 mg K g−1. As expected, delaying the harvest until spring reduced overall yield and nutrient contents (12 t DM ha−1, 3.3 mg N g−1, and 5.5 mg K g−1). At lower latitudes, the late‐ripening M. sacchariflorus × sinensis GRC 14 and GRC 15 combined high yields with low nutrient contents. At the most elevated latitude location (UK), the early‐ripening M. sinensis × sinensis combined high biomass yields with low nutrient offtakes. The clonal Miscanthus × giganteus with intermediate flowering and senescence attained similar low nutrient contents by spring harvest at all four locations. Seasonal changes in yield and nutrient levels analysed in this study provide: (1) a first step towards recommending hybrids for specific locations and end uses in Europe; (2) crucial data for determination of harvest time and practical steps in the valorization of biomass; and (3) key sustainability data for life cycle assessments. Identification of trade‐offs resulting from genetic × environment × management interactions is critical for increasing sustainable biomass supply from miscanthus grown on marginal lands.

“…The main environmental problems associated with short-rotation woody crops in relation to plant nutrients include changes-either depletion or accretion in elemental content of the soil and disposal of ash or other wastes left after burning or other processes using the biomass [12]. Furthermore, a high ash and potassium concentration lower its calorific value [52]. On the other hand, wood ash can be used to fertilize and increase soil pH, thus improving plant growth [12].…”

Fertilization of willow with nitrogen is an important issue with economic and environmental implications. The study was aimed at determining the effect of nitrogen fertilization and white clover on weed infestation, morphology, biomass and chemical composition of willow. A field experiment was established at Wroclaw University of Environmental and Life Sciences (Poland) during the years 2013–2017 with the use of a randomized complete block design (RCBD). The results showed that the number and dry mass of weeds per m2, the number of willow shoots and the fresh weight yield of willow were smaller where the clover was sown. The plants were found to be higher after applying nitrogen fertilization. The dry mass yield and shoot diameter did not depend on the cultivation method. Nitrogen fertilization increased the ash content. Undersowing willow with white clover, higher nitrogen content was found. Nitrogen fertilization increased the content of ash, and in undersowing cultivation, the willow stems had higher nitrogen content than in monoculture. On average, the phloem had 5.6 times higher crude ash content and 4.6 times higher nitrogen content than wood. On the basis of the conducted research, it can be concluded that in the first years after planting, the undersowing growing of willow with white clover can be an alternative to plantations fertilized and non-fertilized with nitrogen.
