“…The other outstanding stretching vibration peak assigned to the first-order aliphatic OH and ether was present at 1027 cm −1 . Similar lignin spectrum was reported by Jonglertjunya et al (2014) and Zeng et al (2012). In cellulose spectrum, O-H and C-H bending vibration was present in the range of 1430-1235 cm −1 , and the characteristic asymmetric stretching vibration peak of C-O-H and C-O-C was observed at 1019 cm −1 .…”

Effects of surface modification by carboxyl group on Pb 2+ adsorption performances and stability of peanut shell and its extracts (cellulose, lignin, and hemicellulose) were investigated. Stability of the biosorbents was measured by determining organic compound release amount (TOC). Results showed that adsorption capacity of peanut shell and the extract was poor and stability of them was not good enough. Amount of organic compound released from the unmodified sorbents followed the order: cellulose > lignin > peanut shell > hemicellulose. Hemicellulose was the main organic compound release resource for the raw peanut shell. Due to the poor stability of the raw materials, peanut and its extract could not be used directly in the practical waste water treatment. After modification, adsorption capacity of peanut shell, cellulose, lignin, and hemicellulose increased by 4-to 6-folds. Stability of the modified sorbents also increased significantly, and TOC determined for the modified peanut shell, cellulose, and hemicellulose was lower than 4.0 mg L −1 in the optimum pH range from 4.0 to 6.0 even using for 30 days, which was lower than the drinking water standard in China. Modified peanut shell and its extract except for lignin could be used safely in pH ranged from 4.0 to 6.0. Surface modification could improve the adsorption performances and stability of the biosorbents.

“…Lignin is reportedly extracted with aqueous solution and ethanol solution. The yield of lignin has been reported to be higher with 40% NaOH in distilled water (20.4%) than that of 40% NaOH in 50% ethanol (9%) ( Jonglertjunya et al., 2014 ).…”

“…Characterization of PHA has been done using XRD analysis, UV-visible spectrophotometry, Differential Scanning calorimeter (DSC) analysis, Proton nuclear magnetic resonance (H-NMR) and Fourier transform infrared spectroscopy (FTIR) ( Salgaonkar and Bragança, 2017 ). The FT-IR spectra for PHA, collagen, and lignin were obtained in the range of 400–4000 cm −1 ( Jonglertjunya et al., 2014 ; Alsafadi and Al-mashaqbeh, 2016 ; Zhou et al., 2016 ). According to few researchers, the degree of deacetylation (DDA) in chitin and chitosan can be estimated in FT-IR using band ratio method and NMR using integrals of the peak of the proton, while, hemicelluloses can be analyzed by FT-IR and spectrum normalized to band nearest 900 cm −1 ( Brienzo et al., 2009 ).…”

Uncontrolled decomposition of agro-industrial waste leads to extensive contamination of water, land, and air. There is a tremendous amount of waste from various sources which causes serious environmental problems. The concern in the disposal problems has stimulated research interest in the valorization of waste streams. Valorization of the wastes not only reduces the volume of waste but also reduces the contamination to the environment. Waste from food industries has great potential as primary or secondary feedstocks for biopolymer production by extraction or fermentation with pre-treatment or without pre-treatment by solid-state fermentation to obtain fermentable sugars. Various types of waste can be used as substrates for the production of biomaterials but recently more focus has been observed on the agro-industrial wastes which have a high rate of production worldwide. This review collates in detail the different food wastes used for biopolymer, technologies for the production and characterization of the biopolymers, and their economic/technical viability.

Organic xerogels were functionalized by incorporating sugarcane bagasse lignin from soda pulping black liquor, not used so far in this materials, with the aim of introducing new functional groups on traditional gels that could improve its adsorptive capacity. Two mixing designs were applied to identify the reactive combinations that allow a well gel formation and to adjust models that predict physical properties. The designs study five components: resorcinol (R, 0.04–0.3), lignin (L, 0.004–0.14), formaldehyde (F, 0.08–0.17), water (W, 0.45–0.8), and NaOH (C, 0.0003–0.0035). The first experimental design was an extreme vertices design and its results showed shrinkage between 4.3 and 59.7 and a bulk density from 0.54 to 1.3; a mass ratioLR/Fnear 1.5 was required for gel formation. In the second design a D-Optimal was used to achieve better adjusted coefficients and incorporate the largest possible amount of lignin in the gels. Bulk density varies from 0.42 to 0.9, shrinkage varies from 3.42 to 25.35, and specific surface area reaches values of 451.86 m2/g with 13% lignin and 270 m2/g with 27% lignin. High catalyst content improves lignin dissolution and increase shrinkage and bulk density of xerogels and bulk density. Lignin contributes to reducing shrinkage and specific surface area due to his compact and rigid structure.
