“…17 Natural bres or agro-wastes such as jute, sisal, hemp, kenaf, and so on, mainly contain cellulose, hemicelluloses, lignin, and in addition, proteins and a non-negligible amount of mineral oxides. 18,19 As a consequence, they have been attracting the attention of many scientists as "biomass or cleaner materials" with several potential uses in various elds such as biofuels [20][21][22] and bioenergy. [23][24][25] Over the last ten years, sisal or kenaf bre used as a bio-reinforcement for polymers has become a highly preferable alternative to classical petroleum-based bres because of its abundance, price, lightweight, renewability and its 100% biodegradability.…”

“…Lignocellulose, which forms the plant skeletons, is the most common fibers residues which created by the nature and the main constituent of organic waste. Despite previously being considered an environmental problem it gains importance as a source of cellulosic fibers, biomaterials sectors and the energy by bio-fuel production ( Mariño et al., 2015 ; El Sharkawi et al., 2018 ; Darwesh et al., 2018 ). Cellulose is a long chain of homopolymer with repeating units D-glucose, which are joined by ß-1-4 linkages between C-1 of one unit and the C-4 of the next unit.…”

Lignocellulosic fibers, which obtained from Citrus trees trimmings, were modified with Aspergillus flavus (EGYPTA5) enzymes. The non-modified and the modified lignocellulosic fibers were used with low density polyethylene (LDPE) by melt blending brabender method at 170 °C with different ratio (5, 10 and 20 wt%) to obtain wood plastic composites (WPC). The prepared samples were characterized using Fourier-transformed infrared (FT-IR), Scan Electron Microscope (SEM), and Water vapor transmission rate (WVTR) as well as, the mechanical, thermal, biodegradability and swelling properties were examined. The fabricated WPC displayed good mechanical and thermal properties compare with pure LDPE. Also, the WVTR was enhanced by the addition of modified lignocellulosic fibers over the unmodified one. Moreover, the enzymes assay such as cellulase and lignin peroxidase enzymes were estimated and confirming the growing of fungi on the lignocellulosic fiber in solid state fermentation condition to improve lignin peroxidase production and eliminate cellulose enzymes. The fabricated WPC can be used in different environmental application such as packaging system, that it will be green, economic, and partially biodegradable.

“…Lignin is a natural organic polymer that is abundantly available as a byproduct of the production of wood pulp . Moreover, lignin is a renewable, biodegradable, eco‐friendly, and amorphous biopolymer for soluble fertilizer . Cellulose is the most abundant component of plant cell walls and it can also be used to prepare slow‐release urea fertilizers .…”

To develop a slow-release fertilizer with high content of urea, lignin was heated with urea-montmorillonite (M/U) extruded composites to synthesize a novel composite-lignin/montmorillonite/urea (L/M/U). Mechanical test results of the composites showed that the L/M/U exhibited a greater flexure strength and a higher elastic modulus than the unmodified M/U extruded material. Based on the results of the urea release experiments, in the M/U extruded composites, the material with a high urea content exhibited a high urea release rate. By contrast, although the urea content of the 2:1:4 L/M/U formulation was higher than the 2:1:1 and 2:1:2 L/M/U formulations, the former formulation exhibited a lower urea release rate than the latter two formulations. The urea cumulative release (34.6%) of the L/M/U 2:1:4 after 105 h was also lower than that (93.7%) of the M/U 1:1 although the W urea (57.1 wt %) in the former was higher than the W urea (50.0 wt %) in the latter.
