“…It was also observed in the figure that the color of all biodegradable films changed from yellowish to dark. These biodegradation findings are in agreement with those previously reported in another study on lignin/methylcellulose biocomposite films [ 64 ]. The researchers found that the biodegradation rate of lignin/methylcellulose films after being buried in soil for 30 days ranged from 46% to 69% with increasing lignin loading.…”

The development of bioplastic materials that are biobased and/or degradable is commonly presented as an alleviating alternative, offering sustainable and eco-friendly properties over conventional petroleum-derived plastics. However, the hydrophobicity, water barrier, and antimicrobial properties of bioplastics have hindered their utilization in packaging applications. In this study, lignin nanoparticles (LNPs) with a purification process were used in different loadings as enhancements in a Kappaphycus alvarezii matrix to reduce the hydrophilic nature and improve antibacterial properties of the matrix and compared with unpurified LNPs. The influence of the incorporation of LNPs on functional properties of bioplastic films, such as morphology, surface roughness, structure, hydrophobicity, water barrier, antimicrobial, and biodegradability, was studied and found to be remarkably enhanced. Bioplastic film containing 5% purified LNPs showed the optimum enhancement in almost all of the ultimate performances. The enhancement is related to strong interfacial interaction between the LNPs and matrix, resulting in high compatibility of films. Bioplastic films could have additional advantages and provide breakthroughs in packaging materials for a wide range of applications.

“…to overcome the costs, environmental issues, and manufacturing process complications related to synthetic polymers. − Cellulose is the main structural component of any plant, which makes it the most abundant polymeric raw material, characterized also by its broad chemical modifiability, allowing the preparation of different fiber morphologies at micro and nanometric size scales . Cellulose-coated fertilizers are, to date, largely produced using ethyl cellulose and cellulose acetate derivatives due to their hydrophobicity. , Hydrophilic cellulose derivates (e.g., carboxymethyl cellulose, methyl cellulose, hydroxyethyl cellulose) are usually blended or grafted with other polymers, i.e., processed as cellulose hydrogels or used as the coating ingredient of composites to fortify the properties of coated materials, for example. − …”

Even if substantial efforts have been made to produce coated fertilizers with more efficient nutrients release, the development of simple processes using greener materials is still challenging to date. Herein, designed biobased formulations, prepared using biochar materials and oxidized cellulose nanofibers filled into methyl hydroxyethyl cellulose, were developed and then used as coating agents of phosphate fertilizer (triple superphosphate). Biochars were elaborated via direct pyrolysis of lignocellulosic biomass. In the case of the so-called engineered biochar (i.e., montmorillonite modified), a co-pyrolysis process of montmorillonite (MT) and biomass was performed. Nanocomposite films were then prepared from the as-prepared coating formulations prior to examine their surface wetting, swelling capacity, and biodegradability in the soil medium. Collected results show that biochar materials significantly reduce the hydrophilicity of cellulosic materials. Furthermore, the addition of MT during the biomass pyrolysis impacts reaction yield (by 54.54%) and also tunes the porous structure of biochar. Moreover, this MT addition induces a decrease of the swelling capacity and degradation rate of cellulose/biochar films by a factor of 45.74 and 44.48%, respectively. Interestingly, the developed cellulose/ engineered biochar coating material induces an increase of the crushing strength of fertilizer granules by 30.29% in comparison with the uncoated fertilizer. Furthermore, the soil water holding capacity was also considerably improved by 7.78% with a water retention capacity of 3.00% after 25 days when cellulose/engineered biochar-coated fertilizer was added into the soil. In fact, this fertilizer impacts considerably on the release of phosphorus (P) in the soil with a reduction of 43.90% of P leaching within 80 days of soil incubation. These findings indicate that the biobased developed nanocomposite formulations of cellulosic biochars are suitable to produce slow-release phosphate fertilizers with reduced P leaching and water-saving properties.

“…Due to the hydrophilic nature of the cellulosic materials, all the samples show a small weight loss of around 100 °C due to the evaporation of absorbed moisture. 47 undergoes a two-step degradation which is conrmed by the presence of two peaks in the DTG curve, the rst degradation occurred at 279 °C and the second one at 340 °C, the rst degradation is attributed to the decomposition of hemicellulose and lignin, the second degradation is attributed to the decomposition of cellulose. It's noteworthy to mention that the degradation of the ATF and CMF samples follows an almost identical degradation behaviour, as shown in TGA and DTG curve, indicating that most of the hemicellulose and lignin were removed aer the alkali and bleaching treatment.…”
