Biomass valorisation of Arundo donax L., Miscanthus × giganteus and Sida hermaphrodita for biofuel production

Abstract

The potential of energy crops Sida hermaphrodita on organic farm'.A b s t r a c t. In the context of the growing demand for biomass, which is being encouraged by the EU directives on the promotion of the use of renewable energy, recent investigations have been increasingly focused on fast-growing energy crops. The aim of this study was to investigate the energy properties of three types of agricultural energy crops: Arundo donax L., Miscanthus × giganteus and Sida hermaphrodita. This investigation looked into the content of non-combustible and combustible matter, higher and lower heating values, lignocellulose content, and biomass macro-elements. The results indicate that the energy values of these crops are comparable, while their lignocellulose content shows significant variations. Thus, Arundo donax L. can best be utilised as solid biofuel due to its highest lignin content, while Miscanthus × giganteus and Sida hermaphrodita L. can be used for both liquid and solid biofuels production. As far as Arundo donax L. is concerned, a higher ash level should be taken into consideration.K e y w o r d s : energy crops, energy values, chemical composition

Application of Hydrodynamic Cavitation for Improving Methane Fermentation of Sida hermaphrodita Silage

“…The obtained results of lignocellulose composition in Sida hermaphrodita are slightly different from those presented by other authors [21,22]. Krička et al [22] reported that the contents of cellulose, hemicellulose, and lignin were about 40.1%, 27.2%, and 26.4%, respectively. These differences resulted from the present study investigating the composition of the substrate (Sida hermaphrodita mixed with cattle manure).…”

Miscanthus: A fast‐growing crop for environmental remediation and biofuel production

“…Analysis of the Miscanthus lignocellulose components is mainly focused on four species: M. sacchariflorus, M. sinensis, M. floridulus, and M × g. According to the various reports in literature, the cellulose content of M × g (approximately 41%) is slightly higher than others while there is no significant difference in hemicellulose content among the four species (Tajana et al, 2017). The average cellulose content of M. sacchariflorus, M. sinensis, M. floridulus, and M × g are 38.9%, 37.6%, 37.2%, and 41.1%, respectively (Lee & Kuan, 2015).…”

Two Novel Energy Crops: Sida hermaphrodita (L.) Rusby and Silphium perfoliatum L.—State of Knowledge

“…In Europe in 2017, about 59% of renewable energy was provided from bioenergy, and globally about 10% of this is derived from agriculture [2]. Important bioenergy crops in Europe include maize (Zea mays L.) to produce biogas and bioethanol, and short rotation coppice [3] and Miscanthus [4] for the production of solid biofuel.…”
