“…The proportion of these units in the molecular structure of lignin depends on its origin and extraction process, and its important effect on the properties of lignin has already been discussed in the literature . Moreover, not only the structure but also the amount of lignin in lignocellulosic biomass varies depending on the original material, reaching values up to 40 wt % in wood , whereas it usually presents values between 5 and 25 wt % in the case of nonwoody, herbaceous biomass. , …”

New biobased polyurethane (PU) coatings with high lignin content were developed and characterized in this work. These materials were based on a α,ω-diisocyanate monomer (1,4-bis(4-isocyanato-2-methoxyphenoxy)butane, VA-NCO) obtained from lignin-derived vanillic acid and its further cross-linking reaction with three different nonchemically modified technical lignins obtained from different pulping processes, namely, mild acetone organosolv, kraft, and soda. After determining the optimal VA-NCO/lignin mass ratio for each type of lignin, an in-depth characterization of the obtained PU coatings highlighted their high biomass content, effective cross-linking, improved thermal stability, hydrophobic character, good adhesion performance on different types of substrates, and tunable mechanical response. These properties were found to be well-correlated to the chemical–physical features of the parent lignins used (namely, molecular weight, glass transition temperature, distribution of phenylpropane subunits, and −OH content), thereby suggesting the possibility to predictively tailor the characteristics of such biobased PU coatings by lignin selection. The results of this study demonstrate that the reaction of a lignin-derived biobased diisocyanate with different chemically unmodified technical lignins represents an interesting pathway for the production of thermosetting PU coatings with a high biomass content that can find application as high-performance biobased materials alternative to traditional petroleum-based platforms.

“…In addition, maize has been proven to be a suitable intercropping species, for example with legumes [37][38][39][40][41] or perennial wild plant mixtures [42][43][44][45]. Biogas production [46] was chosen as the utilization option, as it has recently been found to be a both economically and environmentally promising utilization pathway for miscanthus and other perennial industrial crops [18,47,48]. We hypothesized that the establishment of miscanthus under maize would lead to higher accumulated biomass yields over a three-year cultivation period than for the miscanthus mono-cultivation reference.…”

How to Generate Yield in the First Year—A Three-Year Experiment on Miscanthus (Miscanthus × giganteus (Greef et Deuter)) Establishment under Maize (Zea mays L.)

et al. 2019

Miscanthus is one of the most promising perennial herbaceous industrial crops worldwide mainly due to its high resource-use efficiency and biomass yield. However, the extent of miscanthus cultivation across Europe is still lagging far behind its real potential. Major limiting factors are high initial costs and low biomass yields in the crop establishment period, especially the first year. This study explores the possibility of establishing miscanthus under maize to generate yields from the first year of cultivation onwards. A field trial with mono-cropped maize and two miscanthus establishment procedures, ‘under maize’ (MUM) and ‘standard’ (REF), was established in southwest Germany in 2016. Annual aboveground biomass was harvested in autumn (2016–2018). In 2016 and 2017, the miscanthus dry matter yield (DMY) was significantly lower in MUM than REF. However, the accumulated DMY of miscanthus and maize was as high in MUM as in maize cultivation alone. In 2018, there was no significant difference between the miscanthus DMY of REF (7.86 ± 0.77 Mg ha−1) and MUM (6.21 ± 0.77 Mg ha−1). The accumulated DMY over the three years was 31.7 Mg ha−1 for MUM, of which 10.1 Mg ha−1 were miscanthus-based, compared to 17.7 Mg ha−1 for REF. These results indicate that miscanthus establishment under maize could compensate for its lack of yield in the first year.

“…The chemical composition of the different herbaceous and oilseed crops is presented in Table 1, for easier comparison between them. (2)(3)(4), palmitic (4-7), linoleic (35)(36)(37)(38)(39)(40), oleic (25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40), and α-linolenic ] Miscanthus × giganteus [6,29] ( As can be seen in Table 1, species such as cardoon and linseed have the potential for biodiesel production since oil can be obtained from the seeds. Another species that also has this characteristic, despite not being specified in the table, is hemp, as oil can also be obtained from the seed.…”

“…Giant reed is a poly-annual culture that presents average yields of 15 to 40 t DM ha −1 year −1 [6,28,29]. This species can be applied for energy generation [72], paper pulp, and fiber production (e.g., cellulose for rayon fabrication), and is widely used as an ornamental material for basket-work manufacture, barriers to gardens (trellises and garden fences), crude shelters, construction and roofing materials, livestock fodder, fishing rods, and arrows.…”

“…The advantages of energy crops are also applicable to lignocellulosic residues (part of the species not suitable for harvesting), such as straw, bark, leaves, and bagasse from herbaceous species and long fiber and hardwood from forest species. The reuse of any type of biomass waste material such as forest waste (e.g., wood waste from the wood industries and manufacture of pulp and paper), secondary waste (e.g., animal waste, organic material from food companies, solid waste) and agricultural residues (e.g., short-rotation species, cereals, among others) [6] allow reducing both the fuel load deposited in landfills and the still latent dependence on fossil-based feedstocks [7], creating several environmental, social, and economic opportunities. To comply with sustainability criteria, energy crops value chains must present a reduction of GHG emissions when compared to those released by fossil-based value-chains; the biomass production must not affect or alter negatively the quality of groundwater, soil, or air, and for this reason, it is necessary to limit or to avoid the use of chemical products such as fertilizers and pesticides, the biodiversity of the area where the species are planted must be protected to avoid negative effects directly or indirectly, and, finally, at the local level, the crops must not compete with the food sector and, in parallel, should encourage the economic and social growth of the region [6,8,9].…”

Low Indirect Land Use Change (ILUC) Energy Crops to Bioenergy and Biofuels—A Review

et al. 2022

View full text Add to dashboard Cite

Energy crops are dedicated cultures directed for biofuels, electricity, and heat production. Due to their tolerance to contaminated lands, they can alleviate and remediate land pollution by the disposal of toxic elements and polymetallic agents. Moreover, these crops are suitable to be exploited in marginal soils (e.g., saline), and, therefore, the risk of land-use conflicts due to competition for food, feed, and fuel is reduced, contributing positively to economic growth, and bringing additional revenue to landowners. Therefore, further study and investment in R&D is required to link energy crops to the implementation of biorefineries. The main objective of this study is to present a review of the potential of selected energy crops for bioenergy and biofuels production, when cultivated in marginal/degraded/contaminated (MDC) soils (not competing with agriculture), contributing to avoiding Indirect Land Use Change (ILUC) burdens. The selected energy crops are Cynara cardunculus, Arundo donax, Cannabis sativa, Helianthus tuberosus, Linum usitatissimum, Miscanthus × giganteus, Sorghum bicolor, Panicum virgatum, Acacia dealbata, Pinus pinaster, Paulownia tomentosa, Populus alba, Populus nigra, Salix viminalis, and microalgae cultures. This article is useful for researchers or entrepreneurs who want to know what kind of crops can produce which biofuels in MDC soils.
