“…In (Table 1) results of shell, in keeping with Odetoye et al [33] the percentage of cellulose was approximately to obtain in this study and higher than determined by Singh et al [29]. And the amount of hemicellulose in this work 9.84% was average to publish in and lower than puplished in Ewunie et al [30]. The section of lignin in table (13.00%) was higher than circulated in [29] and lower than result mentioned by Ewunie et al [30].…”

“…The measurement of low molecular weight (Table 1) was lower than issued in Singh et al [29]. Direct combustion of jatropha shell was also characterized by ame front instabilities and short combustion periods due to its higher ash content [30]. The rm results seed cake in an average 4.63% of moisture content, 4.51% wax, 4.27% low molecular weight, 1.98% total lipid, 2.00% of ash and 11.57% total carbohydrate.…”

“…Inseemeesak and Areeprasert [ 24 ] reported that ash and extractive contents were removed by the release of steam during the extraction of fibers from Cocos nucifera L. mesocarp. Ewunie et al [ 32 ] reported that the extractive components in pretreated Jatropha curcas fruit shell (JCFS) were comparatively lower than the untreated JCFS. The extractives in plant materials consist of lipids, phenolic compounds, terpenoids, fatty acids, resin acids, sterol esters, sterol, and waxes [ 33 ].…”

Sugarcane straw fiber (SSF) samples were prepared by chemical pulping (CP) and steam explosion (STE). CP (5, 10, 15% NaOH + 0.2% w/w anthraquinone at 121 °C for 1 h) and STE pressure (1.77, 1.96, and 2.16 MPa at 220 °C for 4 min) SSF trays were molded with a hydraulic hot-press machine at 120 °C, 7 min, and 1.72 MPa. The yield (%) of SSF from STE (54–60% dry basis (db.)) was higher than CP (32–48% db.). STE trays had greater tensile strength than CP. However, STE’s elongation and compression strength was lower than CP tray samples. The trays made from SSF using STE had less swelling in thickness, longer water wetting time, and a higher water contact angle than those made from CP. The micrographs displayed a smaller size of SSF obtained in STE than the CP. The appearance and area of peaks in ATR-FTIR spectra and XRD diffractograms, respectively, revealed that the STE trays had a larger residual lignin content from the lignin study and a lower crystallinity index than the CP trays. Moreover, the lightness values of the STE trays were lower than those of the CP trays due to lignin retention. The study results indicate that CP is the preferred method for producing SSF packaging material with high flexibility and fiber purity. However, when considering the specific SF of 4.28, the STE treatment showed superior physical and mechanical properties compared to CP. This suggests that STE could be an excellent alternative green pulping technique for producing durable biobased trays. Overall, the findings highlight the potential of STE as a viable option for obtaining trays with desirable characteristics, providing a sustainable and efficient approach to tray production.

“…For example, jatropha press cakes often contain lignocellulosic materials, such as seed husks, which slow the hydrolysis stage of the AD process. If that might be a minor limitation for press cakes, it can be a significant problem for other residues, such as fruit shells, pods, plant stems, and leaves [167]. Some examples of pretreatment methods applied to residues of non-edible oilseeds to be submitted to anaerobic digestion are presented in Table 6 and discussed below.…”

Biodiesel production currently follows a first-generation model using edible oils as raw materials. Such a production model is unsustainable, considering that it is limited by the high cost of edible oils, competes with the food sector, and is linked to deforestation and other environmental threats. Changing the raw material base to non-edible oils provides an opportunity to increase the sustainability of the biodiesel industry and to avoid conflicts with food production. Processing non-edible oilseeds for extracting the oil to be used for producing biodiesel generates large amounts of residues, such as de-oiled cakes, seed husks, and fruit shells and pods as well as plant stems and leaves resulting from pruning and other agronomy practices. Most of those residues are currently disposed of by burning or used in a suboptimal way. Bioconversion following the sugar platform route, anaerobic digestion, or enzyme production provides means for upgrading them to advanced biofuels and high-added value products. Bioconversion of plant biomass, including oilseed residues, requires pretreatment to enhance their susceptibility to enzymes and microorganisms. This review provides an outlook on bioconversion approaches applicable to different residues of oilseed-bearing plant species. Recent reports on the pretreatment of non-edible oilseed residues for enhancing their bioconversion through either the sugar platform route or anaerobic digestion are critically discussed. This review is based on an exhaustive Web of Science search performed in January–May 2023.
